Nexperia USA Inc. PUMD30,115

Overview

PUMD30 from Nexperia is an AEC-Q101-qualified NPN/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, featuring integrated 2.2 kΩ input bias resistors (R1), 50 V V_CEO, 100 mA output current per transistor, and dual-channel complementary switching for low-current peripheral control.

For engineers reviewing the PUMD30 datasheet, PUMD30 pinout, PUMD30 application, or PUMD30 equivalent, this device serves as a space- and BOM-optimized alternative to discrete BC847BPN pairs in automotive signal conditioning, IC input driving, and bidirectional load switching where thermal derating on FR4 PCBs and junction temperature limits up to 150 °C must be respected.

Technical Context

The PUMD30 integrates two monolithically isolated transistors - TR1 (NPN) and TR2 (PNP) - each with a dedicated 2.2 kΩ base-input resistor (R1) and open R2 configuration, enabling direct logic-level drive without external bias networks. Its complementary topology supports push-pull or level-shifting functions in compact interfaces.

Each transistor operates within absolute maximum ratings of 50 V V_CEO/V_CBO, 5 V V_EBO, 100 mA I_O, and 200 mW per transistor (300 mW per device) at T_amb ≤ 25 °C on standard FR4. Thermal resistance is 625 K/W per transistor and 416 K/W per device under free-air conditions.

Key Specifications

FAQ

What is the function of R2 in the PUMD30?

R2 is open (not connected) in the PUMD30, as confirmed in the datasheet's "Quick reference data" and "Test information" sections. This configuration provides fixed-base biasing via R1 only, simplifying drive requirements and eliminating need for external feedback or pull-down networks on the base terminals.

Can PUMD30 replace BC847BPN in existing designs?

Yes - the PUMD30 is explicitly cited as a cost-saving alternative to BC847BPN pairs. It integrates two complementary transistors with built-in 2.2 kΩ bias resistors in one SOT363 package, reducing board area by ~50% and eliminating four external resistors required for discrete BC847BPN implementation.

Is thermal derating required for continuous operation at 85 °C ambient?

Yes - per Figure 1, the per-device P_tot derates linearly from 300 mW at 25 °C to ~150 mW at 85 °C ambient on FR4 PCB. Designers must verify total dissipation (I_C × V_CE(sat) + I_B × V_BE) stays below this limit to maintain T_j ≤ 150 °C.

How is the marking code interpreted on PUMD30 devices?

PUMD30 units are marked with "%B3", where "%" is a placeholder for the manufacturing site code (e.g., "A", "B", or "C") and "B3" is the unique device identifier. This matches Table 4 in the datasheet and is verified on Nexperia's official ordering information and packaging documentation.
