Overview
The PDTA115EM,315 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors in a compact SOT323 (SC-70) surface-mounted device plastic package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 20 mA. The internal resistor network consists of R1 at 100 kΩ and R2 at 100 kΩ. It operates within a temperature range of -65 °C to +150 °C. The component is RoHS compliant and supplied in tape and reel packaging for automated assembly.
Feature Summary
- Integrates NPN transistor with dual bias resistors to reduce component count
- Simplifies circuit design through pre-configured resistor ratios
- Compact SOT323 package suitable for space-constrained applications
Applications
- General purpose switching circuits
- Amplification stages
- Circuit drivers
- Inverter and interface circuits
Procurement Notes
Verify the complete part number including the suffix ',315' to ensure correct tape-and-reel packaging configuration. Confirm that the SOT323 package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if required by specific regulatory standards. Ensure storage conditions maintain integrity prior to soldering.
Selection Notes
Select this component when a compact NPN switch with integrated base biasing is required. The 100 kΩ / 100 kΩ resistor ratio suits standard logic level driving applications. Compare against PNP complement PDTA115EM if polarity requirements differ. Verify thermal management needs given the small package size and 20 mA current rating.
Part Context
This part belongs to the PDTA115 series of NPN resistor-equipped transistors from Nexperia. It serves as the NPN counterpart to the PDTA115E series. The device is designed for general-purpose switching and amplification where board space is limited. It replaces discrete transistor and resistor combinations in digital logic interfaces.
Replacement Considerations
Direct functional substitutes include other NPN RETs with similar 50V/20mA ratings and 100kΩ/100kΩ bias networks in SOT323 packages. Verify pinout compatibility and resistor tolerance specifications before substitution. Cross-reference with manufacturer replacement guides for end-of-life status.
