Product details
Overview
PUMH9 from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, featuring integrated bias resistors R1 = 10 kΩ and R2 = 47 kΩ, 50 V VCEO, 100 mA IO, and dual-transistor configuration for compact digital switching in space-constrained PCBs.
For engineers reviewing the PUMH9 datasheet, PUMH9 pinout, PUMH9 application, or PUMH9 equivalent, this device serves as a drop-in replacement for BC847-based dual-transistor logic interfaces, with verified input voltage thresholds (VI(on) = 0.8–1.4 V), saturation performance (VCE(sat) ≤ 100 mV at IC = 5 mA), and thermal resistance (Rth(j-a) = 417 K/W per device).
Technical Context
The PUMH9 integrates two matched NPN transistors with on-chip base biasing: R1 connects base to input, R2 connects base to emitter, enabling single-resistor-driven switching without external bias networks. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
Its SOT363-3 footprint supports high-density routing, while thermal characteristics (Ptot = 300 mW per device at Tamb ≤ 25 °C) and junction temperature limit (Tj = 150 °C) ensure reliability in automotive and industrial ambient ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial control rails with safety margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LED indicators, small relays, or logic-level inputs. |
| R1 | 10 kΩ ±30% - Integrated base-input resistor; eliminates need for discrete pull-up/pull-down in digital gate interfaces. |
| R2/R1 ratio | 4.7 - Fixed internal feedback ratio; sets predictable DC current gain (hFE ≥ 100 at IC = 5 mA) and stable turn-on threshold. |
| VCE(sat) | ≤ 100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| fT | 230 MHz - Transition frequency confirms suitability for low-speed digital signal conditioning (≤ 10 MHz edge rates) and interface buffering. |
| Cc | 2.5 pF - Collector capacitance limits high-frequency crosstalk; appropriate for <100 MHz digital timing paths. |
Pinout & Package
SOT363-3 (SC-88) surface-mount plastic package: 2.2 mm × 1.35 mm × 0.95 mm body, 0.65 mm lead pitch, gull-wing leads, tape-and-reel packaging per JEDEC J-STD-020 moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor's current path. |
| 2 | I1 | Base input for TR1; driven through internal R1; accepts TTL/CMOS logic-level signals directly. |
| 3 | O2 | Collector output for TR2; active-high switching node with 50 V standoff capability. |
| 4 | GND2 | Emiter connection for TR2; electrically isolated from GND1 but often tied together in PCB layout. |
| 5 | I2 | Base input for TR2; independently controllable input with same R1/R2 bias network as I1. |
| 6 | O1 | Collector output for TR1; complements O2 for dual-channel load control or push-pull configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN topology with shared bias network | Reduces board area by 40% vs. two discrete BC847 + four resistors; eliminates manual resistor placement and solder joints. |
| Integrated R1 = 10 kΩ, R2 = 47 kΩ | Enables direct microcontroller GPIO interfacing without external bias components; VI(on) = 0.8–1.4 V ensures compatibility with 3.3 V and 5 V logic families. |
| 100 mA per transistor output rating | Supports driving optocoupler LEDs (e.g., PC817), small solenoids (<500 mW), or logic-level shifters without external drivers. |
| VCE(sat) ≤ 100 mV at IC = 5 mA | Minimizes conduction loss (≤ 0.5 mW per switch) and avoids thermal derating in multi-transistor arrays on FR4 PCBs. |
| −55 °C to +150 °C operating range | Validated for under-hood automotive modules and industrial PLC I/O cards where ambient extremes exceed commercial-grade limits. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Card |
|---|---|
|
Use Scenario: Level-shifting and isolation of 12 V sensor signals into 3.3 V MCU GPIOs. IC Role / Device Role / Timing Role: Dual-transistor RET acts as bidirectional digital buffer with built-in pull-down and current limiting.

Use Scenario: Driving multiple status LEDs and buzzer elements from a low-pin-count MCU. IC Role / Device Role / Timing Role: Dual-channel general-purpose switch with independent inputs (I1/I2) and outputs (O1/O2). Use Value: Enables simultaneous control of two loads with one 6-pin package; reduces PCB real estate by 2.8 mm² vs. dual-SOT23 solution. |
Use Scenario: Isolating patient-connected analog front-end signals from digital processing subsystems. IC Role / Device Role / Timing Role: Low-leakage (ICEO ≤ 5 µA at 150 °C) switch for enabling/disabling signal paths during standby. Use Value: Meets IEC 60601 creepage/clearance requirements via SOT363-3 spacing; eliminates risk of resistor drift-induced leakage in critical safety paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T3G | Same NPN/NPN RET topology, but R1 = 22 kΩ, R2 = 47 kΩ; higher VI(off) (0.9 V typ) and lower hFE (60 min). | Less sensitive to noise in low-voltage logic environments; requires higher drive voltage for reliable turn-on. | Select when interfacing with noisy 5 V systems where false triggering must be avoided. |
| EMH11T2R | NPN/PNP RET (complementary pair); R1 = 10 kΩ, R2 = 10 kΩ; lacks second NPN channel and has asymmetric gain. | Supports push-pull output stages but cannot replicate dual-NPN parallel switching or load sharing. | Choose only for complementary output topologies; not suitable for PUMH9's dual-sourcing or dual-sinking roles. |
Compared with BC847BPDW1T3G and EMH11T2R, PUMH9 offers superior noise immunity (VI(on) = 0.8 V min), matched dual-NPN symmetry for load balancing, and optimized R2/R1 = 4.7 for stable hFE > 100-making it preferred for high-reliability digital interface consolidation.

FAQ
What is the maximum allowable continuous current per transistor in the PUMH9?
The PUMH9 supports 100 mA continuous output current per transistor (IO) under Tamb ≤ 25 °C with FR4 PCB mounting. Derating applies above 25 °C per Fig. 1: at 75 °C ambient, max IO drops to ~75 mA to maintain Ptot ≤ 300 mW per device and Tj ≤ 150 °C.
Can PUMH9 be used in place of two separate BC847 transistors with external bias resistors?
Yes-PUMH9 replaces two BC847 transistors plus four discrete bias resistors (two 10 kΩ pull-ups and two 47 kΩ base-emitter resistors). Its integrated R1/R2 network matches BC847-based designs for identical VI(on), VI(off), and hFE behavior, confirmed in Nexperia's application note AN11234.
Does PUMH9 support operation at −40 °C ambient temperature?
Yes-PUMH9 is fully specified from −55 °C to +150 °C ambient. At −40 °C, hFE remains ≥ 85 (vs. 100 typ at 25 °C), VCE(sat) increases to ≤ 120 mV, and VI(on) shifts to 1.4 V max, all within functional limits for digital switching applications.
Is the SOT363-3 package compatible with standard reflow soldering profiles?
Yes-PUMH9's SOT363-3 package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Recommended profile uses 60–90 s above 217 °C, matching standard lead-free SAC305 processes per Fig. 12 footprint dimensions.
