Overview
The UNR521300L is a Silicon NPN epitaxial planar transistor with built-in bias resistors, designed for digital circuits. It features an S-Mini3-G1 package (SC-70) and supports automatic insertion via tape packing. Key electrical parameters include a collector-emitter voltage of 50 V, a collector current of 100 mA, and a total power dissipation of 150 mW at 25°C. The device incorporates a base resistor (R1) of 47 kΩ and an emitter resistor (R2) of 47 kΩ. It exhibits a transition frequency of 150 MHz and a minimum DC current gain (hFE) of 80 at IC = 5 mA and VCE = 10 V.
Feature Summary
- Integrates dual bias resistors to reduce component count and equipment size
- Utilizes compact S-Mini3-G1 surface-mount packaging for automated assembly
Applications
- Digital logic interface circuits
- Switching applications in general electronic equipment
- Automated insertion into consumer appliances and measuring instruments
Procurement Notes
Verify the specific suffix '00L' against the manufacturer's latest datasheet to confirm exact resistance values and binning. Confirm lifecycle status as the UNR521x series includes discontinued variants. Ensure RoHS compliance documentation matches the required regulatory standards for the target market.
Selection Notes
Select this component when a pre-biased NPN transistor is required for digital switching. Verify that the integrated 47kΩ/47kΩ resistor ratio meets the drive requirements. Compare hFE and saturation voltage specifications against load conditions. Ensure the SC-70 footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the Panasonic UNR521x Series of single NPN pre-biased transistors. The series offers various resistor combinations tailored for different logic families. The UNR5213 variant specifically provides equal base and emitter resistance values, distinguishing it from other series members with asymmetric or single-resistor configurations.
Replacement Considerations
Check for direct cross-references within the UNR521x family if resistance values differ. Verify pinout compatibility with alternative SC-70 pre-biased transistors from other manufacturers before substitution.
