Nexperia USA Inc. PUMD10/ZLH

Overview

PUMD10/ZLH 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 bias resistors R1 = 2.2 kΩ and R2 = 47 kΩ, rated for 50 V V_CEO and 100 mA output current per transistor, used for digital logic interfacing and low-current peripheral driving.

For engineers reviewing the PUMD10/ZLH datasheet, PUMD10/ZLH pinout, PUMD10/ZLH application, or PUMD10/ZLH equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in level-shifting, bus buffering, and IC input control circuits where bias network simplification and consistent gain matching are critical.

Technical Context

The PUMD10/ZLH implements two monolithically integrated BJTs - TR1 (NPN) and TR2 (PNP) - each with dedicated on-chip base bias networks (R1 and R2), enabling direct TTL/CMOS-compatible switching without external resistors. The dual-transistor topology supports complementary signal inversion and push-pull-like operation in compact digital interface stages.

Each transistor operates independently with verified DC current gain (h_FE ≥ 100 at I_C = 10 mA, V_CE = 5 V), collector-emitter saturation voltage ≤ 100 mV (I_C = 5 mA, I_B = 0.25 mA), and transition frequencies of 230 MHz (NPN) and 180 MHz (PNP), confirming suitability for medium-speed digital switching up to ~50 MHz.

FAQ

What is the maximum operating temperature for PUMD10/ZLH?

The PUMD10/ZLH has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance (R_th(j-a)) is 417 K/W per device on FR4 PCB, allowing full 100 mA operation up to +85 °C ambient with standard layout.

Can PUMD10/ZLH replace discrete transistors in existing designs?

Yes - the PUMD10/ZLH is pin-compatible with standard SOT363-3 footprints and functionally replaces two discrete transistors plus four bias resistors. Designers must verify that the integrated R1/R2 values (2.2 kΩ / 47 kΩ) match required base drive conditions and that GND1/GND2 isolation meets circuit grounding needs.

Does PUMD10/ZLH support 5 V logic interfacing?

Yes - the NPN transistor's V_I(on) is 0.75–1.1 V and V_I(off) is 0.5–0.6 V, ensuring robust recognition of 5 V TTL logic levels. The PNP transistor accepts negative-going inputs down to −12 V, supporting mixed-voltage bus termination and fail-safe shutdown modes.

Is PUMD10/ZLH automotive qualified?

No - the PUMD10/ZLH is not AEC-Q101 qualified and is intended for industrial, computing, and consumer applications. It is not tested or warranted for automotive safety-critical systems, and Nexperia explicitly excludes liability for use in life-support or vehicle-control functions.
