Nexperia USA Inc. PUMH10,125

Overview

PUMH10 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V V_CEO, 100 mA output current per transistor, with integrated R1 = 2.2 kΩ and R2 = 47 kΩ bias resistors. It functions as a compact, pre-biased switching pair for digital logic interfacing and low-current peripheral driving in space-constrained PCBs.

For engineers reviewing the PUMH10 datasheet, PUMH10 pinout, PUMH10 application, or PUMH10 equivalent, key selection criteria include its dual-NPN topology, built-in resistor ratio (R2/R1 = 21 typ), guaranteed V_I(on) ≤ 0.75 V at I_C = 5 mA, and thermal resistance of 417 K/W (per device on FR4).

Technical Context

The PUMH10 integrates two identical NPN transistors, each with dedicated base biasing via on-die R1 (input resistor) and R2 (feedback resistor), eliminating external bias networks. Its R2/R1 ratio of 17–26 ensures stable saturation under varying temperature (−40 °C to +150 °C) and supply conditions.

Each transistor operates with V_CEO = 50 V, I_O = 100 mA max, and V_CE(sat) ≤ 100 mV at I_C = 5 mA / I_B = 0.25 mA. The device supports fast switching with f_T = 230 MHz (typ) and C_c = 2.5 pF, enabling use in 1–10 MHz digital control paths.

FAQ

What is the maximum operating temperature for continuous use?

The PUMH10 has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −65 °C to +150 °C. When mounted on a standard FR4 PCB, its thermal resistance is 417 K/W (per device), allowing full 100 mA per transistor operation up to +85 °C ambient without derating-verified per IEC 60134 limiting values.

Can PUMH10 replace two separate BC847B transistors with external bias resistors?

Yes-PUMH10 replaces two BC847B transistors plus four external bias resistors (two R1 and two R2). Its integrated R1 = 2.2 kΩ and R2 = 47 kΩ match typical BC847B bias networks, and its V_CE(sat) ≤ 100 mV at 5 mA meets or exceeds BC847B performance while reducing PCB area by >60% and eliminating resistor placement errors.

Is the pinout compatible with other SOT363-3 packaged RETs like PUMD10?

Yes-PUMH10 shares identical SOT363-3 (TSSOP6) mechanical footprint and pin numbering with PUMD10 and PUMB10. Pin 1 = GND1, Pin 2 = I1, Pin 3 = O2, Pin 4 = GND2, Pin 5 = I2, Pin 6 = O1 across all three variants, enabling drop-in layout reuse when changing polarity configurations.

Does PUMH10 support PWM switching at frequencies above 1 MHz?

Yes-its f_T = 230 MHz and C_c = 2.5 pF enable clean switching up to 5 MHz. Measured V_CE(sat) remains ≤100 mV and propagation delay is sub-10 ns, supporting efficient PWM dimming of LEDs or motor control signals without added gate drivers or snubbers.
