Nexperia USA Inc. PUMD13-QF

Overview

PUMD13-QF from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, integrating matched bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ per channel. It delivers 100 mA output current per transistor, supports ±30 V input voltage range, and is AEC-Q101 qualified for automotive signal-level switching in space-constrained PCBs.

For engineers reviewing the PUMD13-QF datasheet, PUMD13-QF pinout, PUMD13-QF application, or PUMD13-QF equivalent, this device serves as a compact, bias-resistor-integrated replacement for discrete NPN+PNP pairs in digital logic interfacing, low-current peripheral control, and IC input conditioning - with verified thermal derating, dual-transistor gain matching, and automotive-grade reliability.

Technical Context

This dual RET integrates one NPN (TR1) and one PNP (TR2) transistor sharing no internal connection between channels, each with dedicated built-in base bias resistors. The R2/R1 ratio is tightly controlled at 10 (8–12), enabling predictable saturation behavior without external components.

Each transistor operates independently: TR1 (NPN) has V_CEO = 50 V, h_FE ≥ 100 at I_C = 10 mA, and f_T = 230 MHz; TR2 (PNP) provides symmetric performance with V_CEO = −50 V, h_FE ≥ 100, and f_T = 180 MHz - both rated for T_j ≤ 150 °C and qualified per AEC-Q101.

FAQ

Is PUMD13-QF pin-compatible with earlier PUMD13 variants?

Yes - PUMD13-QF uses the same SOT363-3 (TSSOP6) package and identical pinout as PUMD13-Q, with no mechanical or electrical changes affecting drop-in replacement. The "F" suffix denotes tape-and-reel packaging variant per Nexperia's ordering convention, not functional revision.

What is the maximum allowable input voltage at I1 and I2 pins?

The absolute maximum input voltage is +30 V for I1 (TR1 base) and −30 V for I2 (TR2 base), as specified in Table 5 (Limiting Values). Exceeding these values risks permanent damage to the internal bias resistors or transistor junctions, even with current limiting.

Can PUMD13-QF drive a 100 mA relay coil directly?

Yes - each transistor is rated for 100 mA DC output current with V_CE(sat) ≤ 100 mV at I_C = 5 mA. For a 100 mA relay coil, verify that V_CE(sat) remains ≤ 200 mV at full load (confirmed in Fig. 4 and Fig. 10), and ensure PCB copper area meets 300 mW dissipation requirements.

Does PUMD13-QF require external decoupling capacitors?

No - the device contains no internal regulators or oscillators; its bias resistors are passive and stable. However, a 100 nF ceramic capacitor between each GND pin (1 and 4) and local system ground is recommended to suppress high-frequency noise coupling between channels in mixed-signal layouts.
