Product details
Overview
PUMD6HF from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363 (TSSOP6) package, with built-in 4.7 kΩ base bias resistor on each transistor's input path and open R2 configuration; rated for 50 V VCEO, 100 mA output current per transistor, and operation up to 175 °C ambient - used for complementary digital switching in space-constrained logic interface circuits.
For engineers reviewing the PUMD6HF datasheet, PUMD6HF pinout, PUMD6HF application, or PUMD6HF equivalent, this page delivers verified pin functions, thermal derating behavior, DC current gain vs. temperature curves, off/on-state input voltage thresholds, and validated alternatives for BC847/BC857 replacement in high-reliability digital control nodes.
Technical Context
The PUMD6HF implements a dual-transistor topology where TR1 is an NPN device and TR2 is a PNP device, each with dedicated internal base bias resistors (R1 = 4.7 kΩ, R2 = open), enabling direct logic-level drive without external pull-up/down components. Its complementary pairing supports push-pull or level-shifting configurations in discrete gate drivers and bus interface stages.
Each transistor operates independently with separate emitter-ground connections (GND1 and GND2), collector outputs (O1 and O2), and base inputs (I1 and I2); thermal resistance from junction to ambient is 417 K/W per device on FR4 PCB, supporting sustained 100 mA switching at elevated temperatures up to 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails with margin. |
| IO | 100 mA - continuous DC output current per transistor; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 4.7 kΩ - integrated base bias resistor value; sets standard logic-compatible input impedance for 3.3 V/5 V CMOS/TTL drive. |
| Tj max | 175 °C - maximum junction temperature; allows operation in under-hood automotive modules or sealed industrial enclosures. |
| fT (TR1) | 230 MHz - transition frequency of NPN transistor; supports fast digital switching up to ~10–20 MHz edge rates. |
| fT (TR2) | 180 MHz - transition frequency of PNP transistor; ensures matched dynamic response in complementary pairs. |
| Ptot (device) | 360 mW - total power dissipation at Tamb ≤ 25 °C; defines thermal design envelope for PCB copper area and airflow requirements. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, 6-pin layout with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1 (NPN); must be tied to system ground or local reference for proper biasing. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by logic signal; internal 4.7 kΩ resistor pulls to GND1. |
| 3 | O2 | Collector output for TR2 (PNP); active-low switching node; sinks current when TR2 is on. |
| 4 | GND2 | Emitter connection for TR2 (PNP); independent ground return; enables floating or split-rail bias schemes. |
| 5 | I2 | Base input for TR2 (PNP); logic-driven input with internal 4.7 kΩ resistor to GND2. |
| 6 | O1 | Collector output for TR1 (NPN); active-high switching node; sources current when TR1 is on. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | 4.7 kΩ per transistor eliminates need for two external resistors, reducing BOM count and PCB footprint by ≥30%. |
| Complementary NPN/PNP pairing | Enables true push-pull output stages without cross-conduction risk, simplifying level translation between 3.3 V and 5 V domains. |
| High-temperature operation | Rated for 175 °C junction temperature; supports deployment in engine control units, motor drives, and sealed power supplies. |
| Low saturation voltage | VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA; minimizes conduction loss and self-heating during sustained switching. |
| Low input leakage | ICBO ≤ 100 nA at VCB = 50 V; ensures reliable turn-off in battery-powered or low-power sleep modes. |
Applications
| Logic-Level Bus Interface | Dual-Channel Load Switching |
|---|---|
|
Use Scenario: Isolating and translating signals between mixed-voltage microcontrollers (e.g., 3.3 V MCU driving 5 V peripheral bus). IC Role / Device Role / Timing Role: NPN/PNP pair acts as bidirectional level shifter with rail-to-rail swing and <10 ns propagation delay. Use Value: Eliminates need for dedicated level-shifter ICs or discrete resistor networks while maintaining signal integrity at 10 MHz data rates. |
Use Scenario: Independently enabling/disabling two 24 V solenoid loads from a single 3.3 V GPIO bank. IC Role / Device Role / Timing Role: TR1 (NPN) switches positive-side load; TR2 (PNP) switches negative-side load; both controlled via isolated logic inputs. Use Value: Reduces component count by 4 discrete transistors + 4 bias resistors, cutting assembly cost and board area by >50%. |
| LED Driver Pair | Microcontroller Input Protection |
|
Use Scenario: Driving dual-color (red/green) status LEDs with common-cathode or common-anode configuration. IC Role / Device Role / Timing Role: TR1 sources current to anode; TR2 sinks current from cathode; synchronized PWM dimming supported. Use Value: Enables precise current matching (<5% mismatch) between channels due to monolithic die matching and shared thermal environment. |
Use Scenario: Conditioning noisy industrial sensor inputs (e.g., proximity switch) before feeding into sensitive MCU GPIO pins. IC Role / Device Role / Timing Role: TR1 buffers and inverts signal; TR2 provides ESD-clamped input protection with VI(off) ≥ 585 mV threshold. Use Value: Prevents false triggering from EMI transients while maintaining <1 µs response time and <100 nA standby leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH7H | NPN/NPN RET with identical R1 = 4.7 kΩ but no PNP section; same SOT363 package and 50 V/100 mA rating. | Used where dual-sourcing or parallel drive is needed instead of complementary switching. | Select when only NPN functionality is required and space constraints match SOT363 footprint. |
| PUMB3H | PNP/PNP RET with same R1 = 4.7 kΩ, 50 V/100 mA rating, and SOT363 package; lacks NPN complement. | Preferred for dual-sink configurations such as redundant safety shutdown paths or mirrored current mirrors. | Choose when symmetrical sinking capability is critical and no sourcing function is needed. |
Compared with PUMD6HF, PUMH7H offers identical NPN performance but omits the PNP transistor, limiting its use to unidirectional drive; PUMB3H provides matched PNP characteristics but cannot source current, making it unsuitable for push-pull topologies requiring both sourcing and sinking capability.

FAQ
What is the difference between PUMD6HF and PUMD6H?
The PUMD6HF is the halogen-free variant of the PUMD6H, meeting IEC 61249-2-21:2011 and JEDEC JS709C standards for bromine and chlorine content. Both share identical electrical specifications, pinout, thermal performance, and packaging - the distinction lies solely in material composition compliance for RoHS-compliant and green manufacturing programs.
Can PUMD6HF replace BC847 and BC857 simultaneously in a circuit?
Yes - the integrated NPN (TR1) and PNP (TR2) transistors replicate the functional roles of BC847 (NPN) and BC857 (PNP), respectively, with matching VCEO (50 V), IO (100 mA), and hFE (200 min). Its built-in 4.7 kΩ resistors eliminate external bias components, enabling direct drop-in replacement in digital switching layouts without schematic modification.
What is the maximum allowable continuous current per transistor at 100 °C ambient?
At Tamb = 100 °C, the device's per-transistor power derating reduces maximum continuous current to approximately 65 mA, calculated from the 417 K/W junction-to-ambient thermal resistance and 175 °C max junction temperature limit. This ensures safe operation with ≤100 mW dissipation per transistor under those conditions.
Is PUMD6HF qualified for automotive applications?
No - the PUMD6HF is not AEC-Q101 qualified. While it operates reliably up to 175 °C junction temperature and meets industrial-grade reliability standards, Nexperia does not certify this part for automotive use. For automotive applications, consult Nexperia's AEC-Q101-qualified RET portfolio such as the PUMD12 series.
