Product details
Overview
PUMD3-QF from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363-3 (TSSOP6) package, with built-in bias resistors R1 = 10 kΩ and R2 = 10 kΩ, rated for 50 V VCEO and 100 mA output current per transistor, used for digital switching and IC input control in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the PUMD3-QF datasheet, PUMD3-QF pinout, PUMD3-QF application, or PUMD3-QF equivalent, this page delivers verified electrical specifications, AEC-Q101 qualification status, thermal derating curves, dual-transistor biasing behavior, and direct alternatives for cost-optimized digital logic interfacing.
Technical Context
The PUMD3-QF implements two complementary BJT devices - TR1 (NPN) and TR2 (PNP) - each with integrated base bias networks enabling direct logic-level drive without external resistors. Its dual-polarity configuration supports push-pull or complementary switching topologies in level translation and load control circuits.
Each transistor operates independently with separate emitter (GND1/GND2), base (I1/I2), and collector (O1/O2) terminals. The R2/R1 ratio of 1.0 ±0.2 ensures matched turn-on thresholds across both transistors, while fT values of 230 MHz (TR1) and 180 MHz (TR2) confirm suitability for high-speed digital switching up to ~50 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ ±30% - Integrated base input resistor; eliminates need for external pull-up/down, reducing BOM count by two resistors. |
| R2/R1 | 1.0 ±0.2 - Matched internal resistor ratio; ensures consistent VI(on)/VI(off) thresholds between NPN and PNP sections. |
| fT (TR1) | 230 MHz - Transition frequency of NPN transistor; supports clean digital edge response in <10 ns switching applications. |
| fT (TR2) | 180 MHz - Transition frequency of PNP transistor; maintains symmetrical high-speed performance in complementary pairs. |
| Ptot (device) | 300 mW at Tamb ≤ 25 °C - Total power dissipation limit; requires thermal derating above 25 °C per Fig. 1 curve. |
Pinout & Package
SOT363-3 (TSSOP6) surface-mount plastic package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference for first transistor's current path. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by 1.8–5 V logic; no external resistor required. |
| 3 | O2 | Collector output for TR2 (PNP); sinks current when TR2 is active; connects to load return path. |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground node enabling floating or split-rail operation. |
| 5 | I2 | Base input for TR2 (PNP); accepts negative-going or low-side logic signals; VI(off) = 1.1 V typical. |
| 6 | O1 | Collector output for TR1 (NPN); sources current when TR1 is active; connects to load supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive applications including engine control, body electronics, and ADAS sensors. |
| Integrated R1/R2 network | Eliminates four external bias resistors in dual-transistor switch designs, cutting PCB area and assembly cost. |
| Matched VI(on)/VI(off) | VI(on) = 1.8–2.5 V (TR1), VI(on) = −1.8 to −2.5 V (TR2); enables symmetric logic-level compatibility. |
| Low Cc | 2.5 pF (TR1), 3 pF (TR2); minimizes capacitive loading on driving logic and improves signal integrity. |
| Thermal resistance (j-a) | 417 K/W (per device on FR4); supports 300 mW dissipation with ≤125 °C junction rise at 25 °C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-polarity resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH11-Q | NPN/NPN configuration; identical R1/R2 values and SOT363-3 package; lacks PNP section. | Only suitable where dual-NPN logic buffering or parallel drive is needed; cannot replace PUMD3-QF in complementary switching. | Select when designing NPN-only arrays or needing higher hFE consistency across channels. |
| PUMB11-Q | PNP/PNP configuration; same package and bias network; no NPN transistor present. | Applicable only for dual-sink topologies; cannot replicate PUMD3-QF's push-pull capability or level-shifting versatility. | Choose for redundant sink drivers in fail-safe industrial I/O modules requiring dual-channel redundancy. |
Compared with PUMD3-QF, PUMH11-Q and PUMB11-Q offer channel-matched gain and bias but lack cross-polarity functionality - making them unsuitable for applications requiring simultaneous sourcing and sinking from a single package, such as H-bridge pre-drivers or bidirectional bus terminators.

FAQ
What is the maximum operating temperature for PUMD3-QF in continuous use?
The PUMD3-QF has a maximum junction temperature (Tj) of 150 °C and a storage temperature range of −65 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided 35 µm copper, its thermal resistance is 417 K/W; derating begins above 25 °C ambient, reaching zero power at 125 °C ambient per Fig. 1.
Can PUMD3-QF replace BC847-Q/BC857-Q pairs in existing designs?
Yes - the PUMD3-QF is explicitly positioned as a cost-saving alternative to BC847-Q (NPN) and BC857-Q (PNP) discrete pairs. It integrates both transistors and their four bias resistors into one SOT363-3 package, reducing board space by >40% and eliminating manual resistor placement while maintaining compatible pin-compatible drive characteristics.
Does PUMD3-QF support 1.8 V logic-level input drive?
Yes - VI(on) for TR1 (NPN) is specified at 1.8 V minimum (typical 2.5 V) at IC = 10 mA, and VI(off) is 1.1 V typical, confirming reliable turn-on with 1.8 V CMOS outputs. TR2 (PNP) exhibits symmetric behavior with VI(on) = −1.8 V, supporting direct interface with low-voltage microcontrollers.
How does the R2/R1 ratio affect switching behavior in PUMD3-QF?
The R2/R1 ratio of 1.0 ±0.2 ensures matched base current injection between TR1 and TR2, resulting in nearly identical VI(on) and VI(off) thresholds. This symmetry minimizes timing skew in complementary switching applications and prevents shoot-through in push-pull configurations when driven by shared logic signals.
