Product details
Overview
PUMH9-QH from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (TSSOP6) package, rated for 50 V VCEO, 100 mA per transistor output current, with integrated R1 = 10 kΩ and R2 = 47 kΩ bias resistors. It serves as a compact, AEC-Q101-qualified digital switching element for automotive signal conditioning and IC input control.
For engineers reviewing the PUMH9-QH datasheet, PUMH9-QH pinout, PUMH9-QH application, or PUMH9-QH equivalent, this device offers verified dual-transistor logic-level switching with built-in biasing, reduced BOM count, and thermal derating validated on FR4 PCBs - critical for space-constrained automotive body electronics and industrial I/O modules.
Technical Context
The PUMH9-QH integrates two matched NPN transistors with monolithically embedded base bias networks: R1 (input resistor) and R2 (feedback resistor), forming a fixed-current gain configuration optimized for saturated switching. Its dual-emitter-grounded topology enables independent control of each transistor's base via pins 2 (I1) and 5 (I2), while collectors (pins 6 and 3) drive separate loads.
Designed for digital interface applications, it operates within −55 °C to +150 °C ambient range, supports 200 mW per transistor and 300 mW per device power dissipation on standard FR4, and delivers hFE ≥ 100 at IC = 5 mA, VCE = 5 V - ensuring reliable turn-on under low-drive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching window for 24 V automotive systems. |
| IO | 100 mA - Continuous DC output current per transistor; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 10 kΩ ±30% - Input bias resistor value; sets base current for predictable saturation with 3.3 V/5 V logic-level inputs. |
| R2/R1 ratio | 4.7 - Fixed feedback ratio enabling stable current gain and noise immunity in digital switching mode. |
| VCE(sat) | 100 mV max at IC = 5 mA, IB = 0.25 mA - Ensures minimal conduction loss and compatible with low-voltage logic thresholds. |
| fT | 230 MHz typical - Transition frequency confirming suitability for high-speed digital switching up to ~10 MHz edge rates. |
| Ptot (device) | 300 mW - Total power dissipation limit on FR4 PCB; determines thermal margin in compact layouts without heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T3G | Discrete dual NPN without bias resistors; requires external R1/R2 network per transistor. | Higher design flexibility but increases component count and layout area by 4×. | Select when precise bias tuning or non-standard R ratios are required. |
| PUMD9-Q | NPN/PNP complement; single device with mixed polarity outputs and shared R1/R2 values. | Supports push-pull or complementary switching topologies not possible with NPN/NPN-only PUMH9-QH. | Select for H-bridge gate drive or bidirectional signal routing where polarity inversion is needed. |
Compared with BC847BPDW1T3G, PUMH9-QH reduces bill-of-materials and layout complexity at the cost of fixed bias ratios; versus PUMD9-Q, it provides matched NPN characteristics essential for parallel load switching but lacks complementary output capability.

FAQ
What is the maximum operating temperature for PUMH9-QH?
The PUMH9-QH has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. On a standard FR4 PCB, its thermal resistance is 417 K/W (junction-to-ambient, per device), allowing continuous operation at +105 °C ambient with full 100 mA per channel loading when derated per Figure 1.
Can PUMH9-QH be used in linear amplifier configurations?
No - the PUMH9-QH is optimized for saturated switching operation only. Its built-in R1/R2 network fixes the base bias point, and its hFE specification (≥100 at IC = 5 mA) applies only under digital switching conditions. Linear amplification requires externally adjustable bias, which this RET does not support.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 4.7 provides negative feedback that stabilizes the transistor's DC operating point against temperature drift and process variation. This improves consistency of VCE(sat) and reduces sensitivity to input voltage fluctuations - critical for robust digital interface performance in automotive environments.
Is there a lead-free and RoHS-compliant version of PUMH9-QH?
Yes - the PUMH9-QH is manufactured using lead-free solderable terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms full material declaration compliance and provides test reports upon request for automotive and medical customers.
