Overview
The KN4A4M(0)-T1-A is a PNP silicon transistor with built-in resistors, manufactured by Renesas Electronics Corporation. It operates within a collector-to-emitter voltage range of -50 V and supports a continuous DC collector current of -0.1 A. The device features an integrated base resistor (R1) of 10 kΩ and an emitter-to-base resistor (R2) of 10 kΩ. It utilizes the SC-75 (USM) package and maintains a junction temperature rating up to 150 °C.
Feature Summary
- Complementary design counterpart to the KA4xxx series
- Integrated dual-resistor configuration for simplified circuit layouts
- Compact surface-mount packaging suitable for space-constrained applications
Applications
- General-purpose switching circuits
- Logic interface buffering
- Resistive load driving
Procurement Notes
Verify component authenticity through authorized Renesas distributors or sales offices. Confirm that the specific ordering suffix matches the required package variant and quality grade. Ensure compliance with export control regulations before international transactions. Review the latest datasheet revisions for any updates to absolute maximum ratings prior to final procurement decisions.
Selection Notes
Select this component when a compact PNP transistor with pre-integrated biasing resistors is required. Verify that the 10 kΩ internal resistance values align with the target logic levels and drive currents. Ensure the SC-75 package dimensions fit the available PCB footprint. Check thermal dissipation requirements against the 0.2 W total power limit under expected ambient conditions.
Part Context
This part belongs to the KN4xxx family of resistor-built-in PNP transistors. It serves as the complementary counterpart to the KA4xxx NPN series. The product line was originally developed by NEC Electronics Corporation before the company merged with Renesas Technology Corporation in April 2010. Documentation may still reference the legacy NEC branding.
