Nexperia USA Inc. PUMD13,115

Overview

PUMD13 from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363-3 (SC-88) package, rated for 50 V V_CEO, 100 mA output current per transistor, with built-in bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ (R2/R1 = 10), used for compact digital logic interfacing and low-current peripheral control.

For engineers reviewing the PUMD13 datasheet, PUMD13 pinout, PUMD13 application, or PUMD13 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 input voltage thresholds (VI(on) = 0.9–1.3 V, VI(off) = 0.5–0.6 V) and guaranteed saturation (V_CEsat ≤ 100 mV at IC = 5 mA) are critical.

Technical Context

The PUMD13 implements two independent RETs - TR1 (NPN) and TR2 (PNP) - each with monolithically integrated base bias resistors enabling direct TTL/CMOS-compatible drive without external components. The NPN section delivers h_FE ≥ 100 at IC = 10 mA and f_T = 230 MHz; the PNP section provides h_FE ≥ 100 at IC = −10 mA and f_T = 180 MHz.

Thermal design is constrained by a per-device R_th(j-a) of 417 K/W on FR4 PCB and a total power dissipation limit of 300 mW at T_amb ≤ 25 °C. Input voltage limits are asymmetric: +30 V/−5 V for TR1 (NPN), +5 V/−30 V for TR2 (PNP), reflecting complementary polarity operation.

FAQ

What is the maximum operating temperature for PUMD13?

The PUMD13 is rated for junction temperature up to 150 °C and ambient temperature from −65 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), meaning at 25 °C ambient it can dissipate up to 300 mW before reaching max T_j. Derating is required above 25 °C per the published curve.

Can PUMD13 replace two separate SOT23 transistors in a design?

Yes - the PUMD13 integrates one NPN and one PNP transistor with matched bias networks into a single SOT363-3 package, directly replacing two discrete SOT23-3 devices plus four external base resistors. This reduces PCB area by ~40%, eliminates placement errors, and cuts pick-and-place cycle time.

How does the R2/R1 ratio affect switching performance?

The fixed R2/R1 = 10 ratio ensures optimal base biasing for saturation across process and temperature variations. It guarantees IC/IB ≥ 20 under typical conditions, resulting in V_CEsat ≤ 100 mV and fast turn-off due to R2's discharge path - critical for clean digital transitions without external speed-up capacitors.

Is PUMD13 suitable for automotive applications?

No - the PUMD13 is not AEC-Q101 qualified and is explicitly designated for industrial and consumer use. Nexperia states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems. Automotive designs require verified AEC-compliant alternatives like the PUMD13-Q series (if available) or equivalent qualified RETs.
