Nexperia USA Inc. PUMD3,165

Overview

PUMD3,165 from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363-3 (TSSOP6) package, with built-in 10 kΩ input bias resistors (R1 = R2 = 10 kΩ), 50 V V_CEO, 100 mA I_O, and optimized for digital switching in space-constrained automotive and industrial control circuits.

For engineers reviewing the PUMD3,165 datasheet, PUMD3,165 pinout, PUMD3,165 application, or PUMD3,165 equivalent, this device serves as a drop-in replacement for discrete BC847/BC857 pairs in level-shifting, IC input control, and low-power load switching - where reduced BOM count, simplified layout, and consistent biasing are critical selection criteria.

Technical Context

The PUMD3,165 integrates two complementary transistors on one die: TR1 is an NPN transistor with h_FE ≥ 30 at I_C = 5 mA, V_CE = 5 V; TR2 is a PNP transistor with matching bias network topology and identical R1/R2 = 1.0 ±0.2 ratio. Both transistors share independent base inputs and collector outputs, enabling dual-channel active-low and active-high switching without external resistors.

Its internal resistor network eliminates need for external base biasing components, supports direct microcontroller GPIO interfacing, and maintains stable VI(on)/VI(off) thresholds across −40 °C to +100 °C ambient - with typical VI(on) = 1.8 V (TR1) and −1.8 V (TR2) at I_C = 10 mA.

FAQ

What is the maximum continuous current per transistor in the PUMD3,165?

The PUMD3,165 supports 100 mA continuous output current per transistor (I_O) under standard PCB mounting conditions (FR4, 35 µm copper). This rating applies independently to both TR1 (NPN) and TR2 (PNP) channels, with thermal derating beginning above 25 °C ambient per the 417 K/W junction-to-ambient resistance curve.

Can the PUMD3,165 be used with 1.8 V logic inputs?

Yes - the NPN channel (TR1) has VI(on) = 1.8 V (typical) at I_C = 10 mA, and the PNP channel (TR2) has VI(on) = −1.8 V (typical) under same conditions. These thresholds ensure reliable turn-on with 1.8 V CMOS outputs, though marginally reduced h_FE at low V_BE should be verified in final circuit simulation.

Is the PUMD3,165 automotive-qualified?

The PUMD3,165 is manufactured by Nexperia and aligns with their AEC-Q101-qualified RET portfolio. While this specific variant's qualification status is not explicitly stated in the public datasheet, its 150 °C T_j rating, −65 °C to +150 °C T_amb range, and use in automotive door modules per Nexperia application guidance confirm suitability for automotive environments.

How does the R2/R1 ratio affect switching behavior?

The R2/R1 ratio of 1.0 ±0.2 ensures matched base current injection between TR1 and TR2, resulting in symmetrical VI(on)/VI(off) thresholds and consistent saturation voltage (V_CEsat ≤ 100 mV) across both transistors. Deviations outside this range would cause unequal turn-on timing and increased shoot-through risk in push-pull configurations.
