Nexperia USA Inc. PUMD2/ZLH

Overview

PUMD2/ZLH from Nexperia is an NPN/PNP dual resistor-equipped transistor (RET) in a SOT363 (SC-88) surface-mount package, integrating two complementary bias-resistor transistors - one NPN and one PNP - each with 22 kΩ input bias resistors (R1 = R2 = 22 kΩ), 50 V V_CEO, 100 mA output current capability, and AEC-Q101 qualification for automotive use.

For engineers reviewing the PUMD2/ZLH datasheet, PUMD2/ZLH pinout, PUMD2/ZLH application, or PUMD2/ZLH equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital logic interfacing, level translation, and low-power peripheral driver circuits where built-in biasing eliminates external resistors and simplifies PCB layout.

Technical Context

The PUMD2/ZLH integrates two monolithic transistors - TR1 (NPN) and TR2 (PNP) - sharing no internal connection other than common ground terminals. Each transistor features integrated base-emitter and base-collector bias resistors (R1 = 22 kΩ, R2/R1 ratio = 1.0 ±0.2), enabling direct TTL/CMOS-compatible switching without external bias components.

It operates across −55 °C to +150 °C ambient, supports 100 mA continuous output per transistor, and delivers DC current gain (h_FE) ≥60 at I_C = 5 mA, V_CE = 5 V, with V_CE(sat) ≤150 mV at I_C = 10 mA / I_B = 0.5 mA - confirming suitability for low-voltage, low-power digital control paths.

FAQ

What is the maximum operating temperature for PUMD2/ZLH?

The PUMD2/ZLH has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (R_th(j-a)) is 417 K/W per device on FR4 PCB, meaning at 100 mA continuous load and 25 °C ambient, junction temperature rise is ~42 °C - well within safe margin.

Can PUMD2/ZLH replace two separate BC847/BC857 transistors?

Yes - PUMD2/ZLH replaces one BC847 (NPN) and one BC857 (PNP) plus four external 22 kΩ bias resistors. Its pinout differs (SOT363 vs. individual SOT23), so PCB layout must be updated, but schematic functionality is preserved with identical biasing and switching behavior.

Is the 22 kΩ resistor tolerance critical for logic interfacing?

Yes - the R1 tolerance is ±30% (15.4–28.6 kΩ), verified in Table 2 and Table 8. This ensures reliable turn-on with 3.3 V CMOS outputs (VI(on) = 1.7–2.5 V) while maintaining adequate noise margin (VI(off) = 0.8–1.1 V) against logic low states.

Does PUMD2/ZLH support 1.8 V logic input levels?

No - VI(on) minimum is 1.7 V at I_C = 5 mA, but typical VI(on) is 2.5 V; 1.8 V may not guarantee consistent turn-on across temperature and process variation. For 1.8 V systems, consider EMX11T2R (lower R1 = 10 kΩ) or add external level-shifting.
