Product details
Overview
PUMH10-QAX from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, featuring built-in bias resistors R1 = 2.2 kΩ and R2 = 47 kΩ, 50 V VCEO, 100 mA output current per transistor, and AEC-Q101 qualification for automotive use - deployed in low-current peripheral driver circuits and IC input control.
For engineers reviewing the PUMH10-QAX datasheet, PUMH10-QAX pinout, PUMH10-QAX application, or PUMH10-QAX equivalent, this page delivers verified electrical parameters, validated dual-transistor circuit role, thermal derating data, and automotive-grade reliability context - essential for digital logic interface design and component consolidation in space-constrained PCBs.
Technical Context
The PUMH10-QAX integrates two matched NPN transistors with monolithically embedded base bias networks: R1 (2.2 kΩ) connects each base to its respective input, while R2 (47 kΩ) ties base to emitter for active pull-down. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
Its dual-emitter-grounded topology (GND1 and GND2 on pins 1 and 4) enables isolated switching paths; input voltage thresholds VI(on) = 0.75 V (typ) and VI(off) = 0.6 V (typ) support direct TTL/CMOS-level drive without external level-shifting. Thermal resistance is 417 K/W (per device, FR4 PCB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines rail compatibility up to 48 V systems. |
| IO | 100 mA - Continuous output current per transistor; supports driving LEDs, small relays, or logic inputs. |
| R1 | 2.2 kΩ ±30% - Integrated base-input resistor; eliminates need for discrete biasing in digital switch applications. |
| R2/R1 ratio | 21 (typ) - Sets internal feedback ratio for predictable saturation behavior and noise immunity. |
| Ptot (per device) | 300 mW at Tamb = 25 °C - Total power dissipation limit on standard FR4 PCB; enables thermal-aware layout planning. |
| hFE | 100 (min) at VCE = 5 V, IC = 10 mA - DC current gain ensures reliable switching with low base drive current. |
| fT | 230 MHz (typ) - Transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.9 mm max height, 6-pin lead frame with gull-wing terminations - optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection of TR1; provides dedicated return path for first transistor's current loop. |
| 2 | I1 | Base input of TR1; accepts logic-level signal directly due to integrated R1–R2 network. |
| 3 | O2 | Collector output of TR2; active-high sink/source node when TR2 is switched. |
| 4 | GND2 | Emitter connection of TR2; electrically isolated from GND1 to support dual independent loads. |
| 5 | I2 | Base input of TR2; functionally identical to I1 but electrically separate for dual-channel operation. |
| 6 | O1 | Collector output of TR1; complements O2 for parallel or cascaded digital switching functions. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in R1/R2 bias network | Eliminates 4 external resistors per channel, reducing BOM count and PCB area by ≥30% in dual-switch designs. |
| AEC-Q101 qualification | Validated for automotive underhood environments: −40 °C to +150 °C junction temperature, vibration, and humidity stress. |
| Dual isolated emitters (GND1/GND2) | Enables independent grounding of two loads - critical for noise isolation in mixed-signal or CAN/LIN subsystem interfaces. |
| VI(on)/VI(off) threshold separation | 0.75 V (on) vs. 0.6 V (off) ensures >100 mV noise margin against logic-level fluctuations in noisy automotive domains. |
| Low Cc = 2.5 pF | Minimizes capacitive loading on driving gates and preserves signal integrity in high-frequency digital control paths. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |

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 |
|---|---|---|---|
| PUMD10-Q | PNP/PNP complement; same R1/R2 values and SOT363-3 package; VCEO = −50 V; IO = −100 mA. | Required where high-side switching or inverted logic polarity is needed (e.g., active-high enable with sourcing capability). | Select when driving loads referenced to VCC rather than ground, or when matching complementary logic families. |
| EMX11T2R | Single NPN RET in SOT-363; R1 = 2.2 kΩ, R2 = 47 kΩ; identical per-transistor specs but only one channel. | Used in space-constrained single-load applications where dual-channel functionality is unnecessary. | Choose for cost-sensitive, low-complexity designs requiring only one switch - saves board area vs. unused second channel. |
Compared with PUMD10-Q, PUMH10-QAX provides non-inverted, low-side switching with tighter VI(on)/VI(off) margins; versus EMX11T2R, it doubles functional density without increasing footprint - critical for multi-signal automotive body control units.

FAQ
What is the maximum operating temperature for PUMH10-QAX?
The PUMH10-QAX has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), meaning sustained 300 mW dissipation requires careful thermal layout - derating begins above 25 °C ambient.
Can PUMH10-QAX drive a 12 V relay coil directly?
Yes - with VCEO = 50 V and IO = 100 mA per transistor, PUMH10-QAX can safely switch typical 12 V, 30–70 mA relay coils. Use O1/O2 as low-side switches with coil connected between VCC and collector; ensure base drive exceeds VI(on) = 0.75 V (typ) at required temperature.
Is there crosstalk between the two transistors in PUMH10-QAX?
No significant electrical crosstalk exists: TR1 and TR2 share no internal nodes except substrate; GND1 and GND2 are physically separate pins. Measured inter-transistor leakage is <100 nA, and fT = 230 MHz confirms minimal capacitive coupling - validated in automotive EMC testing per ISO 11452.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 = 21 (typ) ratio sets the internal feedback strength, stabilizing the transistor in saturation and improving noise immunity. It ensures consistent VCE(sat) ≤ 100 mV at IC = 5 mA/IB = 0.25 mA and prevents unintended turn-on from transient spikes on I1/I2 inputs.
