Product details
Overview
PUMH10-QX 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 as a compact logic-level peripheral driver in space-constrained control modules.
For engineers reviewing the PUMH10-QX datasheet, PUMH10-QX pinout, PUMH10-QX application, or PUMH10-QX equivalent, this page delivers verified pin functions, thermal derating behavior, input voltage thresholds (VI(on) = 0.75 V typ, VI(off) = 0.6 V typ), and direct alternatives with documented R1/R2 ratio and saturation voltage differences.
Technical Context
The PUMH10-QX integrates two matched NPN transistors with monolithically embedded base bias networks: each channel includes a 2.2 kΩ input resistor (R1) and a 47 kΩ feedback resistor (R2), yielding a nominal R2/R1 ratio of 21 - enabling single-resistor drive without external bias components. It operates with open-base VCEO = 50 V and supports DC current gain (hFE) ≥100 at IC = 10 mA, VCE = 5 V.
Thermal design is constrained by a per-device Rth(j-a) = 417 K/W on FR4 PCB (single-sided, 35 µm Cu), with total power dissipation limited to 300 mW at Tamb = 25 °C and derating linearly above 25 °C. Junction temperature must not exceed 150 °C under continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V max - defines maximum safe collector-emitter voltage with base open; sets rail compatibility for 24 V automotive logic interfaces. |
| IO | 100 mA max per transistor - supports direct driving of LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - sets input current sensitivity; enables ~1 mA drive at 2.2 V input for reliable TTL/CMOS-compatible switching. |
| R2/R1 ratio | 21 (17–26) - determines internal feedback strength and stabilizes operating point against hFE variation across temperature and unit spread. |
| VCE(sat) | 100 mV max at IC = 5 mA, IB = 0.25 mA - ensures low conduction loss in high-duty-cycle digital switching applications. |
| fT | 230 MHz typ at VCE = 5 V, IC = 10 mA - supports fast edge rates in pulse-width modulation and signal buffering up to ~30 MHz. |
| Ptot (device) | 300 mW max at Tamb = 25 °C - defines thermal envelope for dual-transistor operation on standard FR4; requires derating above 25 °C. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.9 mm max height, tape-and-reel packaging per JEDEC J-STD-020 moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for transistor TR1 - common reference node for first channel; must be tied to system ground or local return path. |
| 2 | I1 | Base input for TR1 - accepts logic-level voltage; internal R1 resistor connects this pin to TR1 base, eliminating external bias network. |
| 3 | O2 | Collector output for TR2 - active-high sink output; used for inverted logic stage or load switching referenced to VCC. |
| 4 | GND2 | Emitter connection for transistor TR2 - independent ground return for second channel; allows separate current paths or isolated loads. |
| 5 | I2 | Base input for TR2 - functionally identical to I1; enables dual independent digital inputs with shared or separated biasing. |
| 6 | O1 | Collector output for TR1 - primary non-inverted output; configured as low-side switch with GND1 as emitter reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with matched R1/R2 networks - eliminates need for four discrete resistors and reduces board area by >60% vs discrete implementation. |
| AEC-Q101 qualification | Stress-tested per Automotive Electronics Council requirements - validated for operation from −40 °C to +150 °C junction temperature in engine control, body electronics, and ADAS subsystems. |
| Input voltage thresholds | VI(on) = 0.75 V (typ), VI(off) = 0.6 V (typ) - provides robust noise margin against 3.3 V and 5 V logic families while minimizing false triggering in noisy environments. |
| Low VCE(sat) | ≤100 mV at 5 mA collector current - reduces power loss and self-heating during sustained ON-state operation in battery-powered modules. |
| Thermal resistance | Rth(j-a) = 417 K/W (per device on FR4) - enables thermal management using standard PCB copper pours without heatsinks in ambient ≤85 °C applications. |

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; R1 = 2.2 kΩ, R2 = 47 kΩ; VCEO = −50 V; |IO| = 100 mA | Used for high-side switching or complementary logic inversion where sourcing current is required instead of sinking. | Select when driving loads referenced to VCC rather than ground, or when matching PNP-based legacy designs. |
| PUMB10-Q | PNP/PNP version with identical R1/R2 but different pinout (GND pins swapped); same AEC-Q101 rating and thermal specs | Requires PCB layout revision due to reversed emitter pin assignments; not drop-in compatible despite functional equivalence. | Choose only if redesigning for PNP-centric topology and layout flexibility exists for pin 1/4 reassignment. |
Compared with PUMH10-QX, PUMD10-Q enables high-side control with matched resistor values but opposite polarity, while PUMB10-Q offers identical electrical behavior with incompatible pin mapping - making PUMH10-QX the sole choice for new NPN/NPN dual-sink designs requiring SOT363-3 footprint compliance.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) for PUMH10-QX is 150 °C. Operation beyond this limit risks permanent degradation of hFE, increased leakage currents, and accelerated failure mechanisms. Derating curves in Figure 1 confirm usable power drops to zero at 150 °C ambient when mounted on standard FR4 PCB.
Can PUMH10-QX replace discrete transistor-resistor combinations in existing designs?
Yes - PUMH10-QX replaces two NPN transistors plus four bias resistors (two R1, two R2) in a single SOT363-3 footprint. Pin compatibility with standard dual-transistor layouts is maintained, though GND1/GND2 separation requires verification of local return path routing in legacy designs.
How does the R2/R1 ratio affect switching performance?
The R2/R1 ratio of 21 stabilizes the transistor's DC operating point against hFE variance and temperature drift. A higher ratio increases feedback, improving saturation depth and reducing sensitivity to input voltage fluctuations - directly enabling consistent VCE(sat) ≤100 mV across −40 °C to +125 °C.
Is the marking code 'H%0' sufficient for lot traceability?
Yes - the marking 'H%0' includes a manufacturing site placeholder (%), which is replaced with a specific alphanumeric code during production. Combined with full traceability documentation from Nexperia's certified supply chain, this enables full lot-level recall and quality history tracking per AEC-Q101 requirements.
