⚡ Note: Voltage grading codes (R2-4) and Current Gain codes (IC22-39) are available for stricter binning selection.
⚠️ Absolute Maximum Ratings & Process Limits
🔒 Exceeding these ratings may cause permanent device failure. Design margins must account for these hard limits under worst-case operating conditions.
| Parameter | Symbol | Ratings | Unit |
|---|---|---|---|
| Power Dissipation | $P_D$ | 75 | mW |
| Forward Current (DC) | $I_F$ | 50 | mA |
| Peak Forward Current | $I_F$ | 1 | A |
| Collector-Emitter Voltage | $V_{CEO}$ | 35 | V |
| Reverse Voltage | $V_R$ | 5 | V |
| Operating Temp | $T_{opr}$ | -20 to +85 | °C |
⚠️ Soldering Constraint: Lead soldering temperature must not exceed 260°C, with a duration limit of 5 seconds kept at a distance >2mm from the epoxy body to prevent thermal damage.
📦 Package, Dimensions & Assembly Notes
The XL-ITR9608 is housed in a standard through-hole mounting package. 🔧 Key mechanical features include:
- Tolerance: Standard dimensions are maintained at $\pm0.3mm$ unless otherwise specified.
- Moisture Sensitivity: The component is classified at MSL 2, requiring proper handling to prevent moisture ingress prior to reflow.
- Assembly: Care must be taken to observe the 2mm clearance from the device body during soldering to ensure epoxy integrity. Physical orientation (emitter vs. detector side) must be strictly followed on the PCB layout.
🛒 Sourcing & Supply Considerations
Procurement teams should verify the specific Voltage Grading and Current Gain codes required by the firmware to ensure signal consistency. 📈 This device offers Pb-Free and RoHS compliant versions, essential for EU market penetration. When sourcing, confirm the Moisture Sensitivity Level (MSL 2) handling procedures are in place at the assembly house. For large-scale BOM optimization, validating the slot machine and scanner application fit with engineering samples is recommended before volume ordering.
❓ Frequently Asked Questions
Q: What is the typical wavelength of the infrared emitter in the XL-ITR9608?
A: The emitter operates at a peak wavelength of 940nm, which is standard for applications requiring minimal interference from visible light sources.
Q: What is the maximum soldering temperature and duration for this component?
A: The maximum soldering temperature is 260°C. It should not be applied for more than 5 seconds, and the iron tip must be kept at least 2mm away from the plastic body.
Q: Can the XL-ITR9608 handle a continuous forward current of 100mA?
A: No. The Absolute Maximum Rating for continuous forward current ($I_F$) is 50mA. While pulse currents up to 1A are permitted, continuous operation above 50mA will likely damage the LED.
Q: What does the "MSL 2" rating mean for assembly?
A: Moisture Sensitivity Level 2 means the components can be exposed to ambient moisture for up to 1 year (at 30°C/85% RH) before requiring baking prior to high-temperature soldering processes.
Q: What is the response time of the detector?
A: Both the rise time ($t_r$) and fall time ($t_f$) are typically 15μs under specified test conditions, making it suitable for high-speed scanning applications.
Q: Are there specific binning options for this sensor?
A: Yes, the datasheet specifies voltage grading codes (e.g., R2-4) and collector current codes (e.g., IC22-39) to allow designers to select parts with tighter tolerances for sensitive circuits.
