Product details
Overview
PUMB3H-Q from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for −50 V VCEO, −100 mA output current per transistor, with built-in 4.7 kΩ base bias resistor (R1) and open R2. It serves as a dual high-temperature switching element in automotive digital control circuits, replacing discrete BC857-based pairs while reducing PCB footprint and assembly cost.
For engineers reviewing the PUMB3H-Q datasheet, PUMB3H-Q pinout, PUMB3H-Q application, or PUMB3H-Q equivalent, this device is selected for AEC-Q101-compliant digital switching where space-constrained dual-PNP logic-level drive, thermal robustness up to 175 °C, and simplified biasing are required - not for linear amplification, high-frequency RF, or power regulation.
Technical Context
This dual RET integrates two matched PNP transistors with dedicated on-die base resistors: R1 = 4.7 kΩ (typical) connected between base and emitter of TR1, while R2 is unconnected (open). Each transistor operates independently with isolated emitters (GND1/GND2), enabling separate load referencing or cascaded switching configurations.
It supports DC switching at ambient temperatures from −55 °C to +175 °C, with junction temperature limited to 175 °C and total device power dissipation up to 360 mW at Tamb ≤ 25 °C on FR4 PCB. Thermal resistance from junction to ambient is 417 K/W (per device), confirming suitability for thermally demanding automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin. |
| IO | −100 mA per transistor - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ (typ) - Integrated base bias resistor simplifies gate drive circuitry and eliminates external component placement. |
| Tj max | 175 °C - Junction temperature rating qualified per AEC-Q101; supports operation in engine control units and body electronics. |
| Ptot (device) | 360 mW at Tamb ≤ 25 °C - Total power handling across both transistors on standard FR4 PCB; defines thermal design envelope. |
| hFE | 200 min at IC = −1 mA - DC current gain ensures reliable saturation with low base drive current in digital switching. |
| VCE(sat) | −100 mV max at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes conduction loss and heat generation. |
Pinout & Package
Package: SOT363 (TSSOP6), 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, surface-mount plastic package qualified for automotive reflow and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; must be tied to local reference ground for TR1 operation. |
| 2 | I1 | Base input for TR1; driven through internal R1; accepts logic-level signals down to VI(off) = −585 mV. |
| 3 | O2 | Collector output for TR2; sinks current when TR2 is active; electrically isolated from O1. |
| 4 | GND2 | Emiter connection for TR2; independent reference node allowing dual-load separation. |
| 5 | I2 | Base input for TR2; no internal resistor (R2 = open); requires external bias network. |
| 6 | O1 | Collector output for TR1; sinks current when TR1 is active; shares package but not electrical path with O2. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 4.7 kΩ typ - Eliminates one external resistor per channel, reducing BOM count and layout area. |
| AEC-Q101 qualification | Qualified for automotive applications - Ensures reliability under temperature cycling, humidity, and mechanical stress per industry standard. |
| Dual isolated emitters | GND1 and GND2 pins - Enables independent grounding of each transistor, supporting mixed-voltage or isolated load switching. |
| High-temperature operation | 175 °C junction limit - Allows deployment in engine control modules, transmission controllers, and other under-hood ECUs. |
| Low VCE(sat) | −100 mV max - Reduces power loss during conduction, critical for thermally constrained PCBs and battery-powered modules. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Output Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD6H-Q | NPN/PNP RET configuration; R1 = 10 kΩ, R2 = 10 kΩ; VCEO = −50 V, IO = −100 mA | Supports complementary logic drive (e.g., one NPN for pull-down, one PNP for pull-up) rather than dual-sink topology | Select when mixed-polarity switching is needed, such as driving push-pull gates or level translators. |
| BC857BDW1T1G | Discrete dual PNP transistor array; no built-in resistors; VCEO = −45 V, IC = −100 mA; SOT363 package | Requires external base resistors; lacks AEC-Q101 qualification; lower VCEO margin | Choose only for non-automotive cost-sensitive designs where full resistor network control is preferred over integration. |

FAQ
Is PUMB3H-Q pin-compatible with BC857BDW1T1G?
No. While both use SOT363 packaging, PUMB3H-Q has internal R1 on Pin 2 (I1) and open R2 on Pin 5 (I2), whereas BC857BDW1T1G has no integrated resistors and identical pin functions across both transistors. Direct replacement requires redesigning base bias networks and verifying VI(off)/VI(on) thresholds.
Can PUMB3H-Q be used in linear amplifier configurations?
No. Its design targets digital switching: hFE is specified only at IC = −1 mA, VCE = −5 V; VCE(sat) and VI(on)/VI(off) are optimized for saturation/cutoff operation; no small-signal parameters (e.g., fT linearity, noise figure) are characterized for analog use.
What is the maximum safe operating frequency for PWM switching with PUMB3H-Q?
Based on fT = 180 MHz (typ) and measured VCE(sat) stability up to 10 kHz in Fig. 7, PUMB3H-Q supports reliable PWM switching up to 20 kHz in automotive BCM applications. Higher frequencies require verification of switching losses and thermal rise using the provided Zth(j-a) curves.
Does PUMB3H-Q support bidirectional current flow or reverse voltage tolerance?
No. As a PNP transistor pair, it conducts only from emitter to collector (sink mode). Reverse voltage tolerance is limited to VEBO = −7 V (emitter-base) and VCBO = −50 V (collector-base); applying reverse VCE beyond −50 V risks permanent damage per absolute maximum ratings.
