Nexperia USA Inc. PUMD48-QH

Overview

PUMD48-QH from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, integrating two bias-resistor-configured transistors - TR1 (NPN, R1 = 47 kΩ, R2 = 47 kΩ) and TR2 (PNP, R1 = 2.2 kΩ, R2 = 47 kΩ) - with 100 mA output current capability, 50 V V_CEO, and AEC-Q101 qualification for automotive signal-level switching.

For engineers reviewing the PUMD48-QH datasheet, PUMD48-QH pinout, PUMD48-QH application, or PUMD48-QH equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital logic interfacing, low-current peripheral drivers, and IC input control circuits where built-in biasing eliminates external resistors.

Technical Context

This dual RET combines one NPN transistor (TR1) with h_FE ≥ 80 at I_C = 5 mA and V_CE = 5 V, and one PNP transistor (TR2) with h_FE ≥ 100 at I_C = −10 mA and V_CE = −5 V, both featuring integrated base bias networks enabling direct TTL/CMOS-level drive without external resistors.

The TR1 NPN has R1 = 47 kΩ ±22%, R2/R1 = 1.0 ±0.2, while TR2 PNP uses R1 = 2.2 kΩ ±30%, R2/R1 = 21 ±24%, supporting complementary on/off control with matched VI(on)/VI(off) thresholds - 1.6 V / 1.2 V (TR1) and −0.75 V / −0.6 V (TR2) - under standard conditions.

FAQ

What is the maximum operating junction temperature for PUMD48-QH?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the limiting values table. Operation above this temperature risks permanent degradation of the silicon die and integrated resistors. Derating is required above 25 °C ambient - total device power must be reduced linearly beyond 300 mW using the 417 K/W thermal resistance value.

Can PUMD48-QH replace discrete NPN and PNP transistors in existing designs?

Yes, provided the original design uses standard small-signal NPN (e.g., BC847) and PNP (e.g., BC857) with 47 kΩ and 2.2 kΩ base resistors respectively. Pin compatibility requires routing adjustments due to SOT363-3's 6-pin layout versus two SOT23 footprints, but no changes to logic thresholds or timing are needed.

Does PUMD48-QH support 3.3 V logic-level input drive?

Yes - TR1 (NPN) turns on at VI(on) ≤ 1.6 V (typical) and TR2 (PNP) at VI(on) ≥ −0.75 V (typical), both well within 3.3 V CMOS output swing. The internal bias network ensures reliable saturation with 3.3 V drive, delivering full 100 mA output without external level shifting.

Is the marking code "4%8" unique to PUMD48-QH?

Yes - "4%8" is the standardized top-side marking for PUMD48-QH, where "%" is a placeholder for Nexperia's manufacturing site code. This marking is distinct from other PUMD-series variants (e.g., PUMD3-Q uses "4%7") and confirms correct device identification during automated optical inspection and traceability audits.
