Product details
Overview
PUMD6H-QF from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT363 (TSSOP6) package, rated for 50 V VCEO, 100 mA output current per transistor, with built-in 4.7 kΩ bias resistor on TR1 and open R2 configuration - used for digital switching and IC input control in automotive-grade circuits.
For engineers reviewing the PUMD6H-QF datasheet, PUMD6H-QF pinout, PUMD6H-QF application, or PUMD6H-QF equivalent, this device serves as a space- and cost-optimized replacement for discrete BC847/BC857 pairs in high-reliability digital interface and load-switching functions requiring AEC-Q101 qualification and 175 °C junction operation.
Technical Context
This dual-transistor integrates one NPN (TR1) and one PNP (TR2) silicon die in a single TSSOP6 package, each with dedicated base resistors - only TR1 includes a 4.7 kΩ integrated bias resistor (R1), while R2 is unconnected (open). The device operates with independent emitter grounding (GND1/GND2) and cross-coupled input/output terminals enabling complementary logic-level switching without external bias networks.
It supports bidirectional signal conditioning: TR1 (NPN) delivers 230 MHz fT and 200 hFE at 1 mA, while TR2 (PNP) provides 180 MHz fT and matched thermal derating up to 175 °C junction temperature, with per-transistor power dissipation limited to 240 mW and 360 mW total device rating under FR4 PCB conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with safety margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 4.7 kΩ ±27% - Integrated base bias resistor on TR1; eliminates need for external pull-up/pull-down in standard switch configurations. |
| 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 high-speed complementarity for push-pull or level-shifting topologies. |
| Tj max | 175 °C - Maximum junction temperature; qualified per AEC-Q101 for under-hood automotive environments. |
| Ptot (device) | 360 mW - Total power dissipation at Tamb ≤ 25 °C on FR4 PCB; defines thermal design envelope for compact layouts. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body; designed for reflow soldering with standardized footprint per Fig. 20.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1 (NPN); common reference for NPN side; must be tied to system ground or low-side return path. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by MCU GPIO or logic signal; internal R1 connects I1 to O1. |
| 3 | O2 | Collector output for TR2 (PNP); active-low switching node; sinks current when TR2 is biased via I2. |
| 4 | GND2 | Emitter connection for TR2 (PNP); independent ground reference for PNP side; enables floating or split-rail biasing. |
| 5 | I2 | Base input for TR2 (PNP); accepts logic-high or pulled-up signal to activate PNP conduction; no internal resistor (R2 = open). |
| 6 | O1 | Collector output for TR1 (NPN); active-high switching node; sources current when TR1 is biased via I1 and R1. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias network | 4.7 kΩ resistor on TR1 base reduces external component count by one resistor per channel in standard switch designs. |
| AEC-Q101 qualification | Stress-tested for automotive reliability including temperature cycling, HTRB, and ESD; suitable for engine control, body electronics, and ADAS interfaces. |
| High-temperature operation | Rated for continuous operation up to 175 °C junction temperature - supports placement near heat sources without derating penalties. |
| Space-efficient dual topology | NPN/PNP pairing in single 2.1 mm × 1.25 mm footprint replaces two discrete SOT23 devices, saving >40% board area versus discrete solutions. |
| Low VI(on)/VI(off) thresholds | TR1 VI(on) = 0.88 V (typ), VI(off) = 585 mV (typ) - compatible with 1.8 V, 3.3 V, and 5 V logic families without level-shifting. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |

Use Scenario: Driving LED status indicators and relay coils in door module ECUs where space and thermal robustness are constrained. IC Role / Device Role / Timing Role: Dual-transistor switch providing isolated NPN sourcing (O1) and PNP sinking (O2) for bidirectional LED drive and optocoupler input conditioning. Use Value: Eliminates four external resistors vs. discrete BC847/BC857 pair; maintains signal integrity across -40 °C to 125 °C ambient with <100 mV VCE(sat). |
Use Scenario: Level translation and isolation between 24 V field sensors and 3.3 V microcontroller GPIOs in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: NPN side (TR1) buffers high-side sensor signals; PNP side (TR2) drives low-side interrupt lines with fast turn-off due to 180 MHz fT. Use Value: VI(off) ≥ 585 mV ensures noise immunity against 24 V transients; 175 °C Tj rating supports sealed enclosure operation without forced cooling. |
| Digital Logic Signal Conditioning | Cost-Sensitive Consumer Power Management |
|
Use Scenario: Inverting/non-inverting signal routing in battery-powered IoT hubs where BOM cost and PCB real estate are critical. IC Role / Device Role / Timing Role: TR1 acts as inverter with R1-biased base; TR2 provides complementary non-inverted output - enabling dual-edge-triggered wake-up paths. Use Value: 230 MHz fT supports clean 10 MHz clock buffering; 100 nA ICEO ensures <1 µA standby leakage per channel. |
Use Scenario: Enabling/disabling auxiliary rails (e.g., USB-C PD negotiation circuitry) in smart home hubs using 3.3 V MCU outputs. IC Role / Device Role / Timing Role: TR1 switches 5 V rail enable line; TR2 controls reset assertion for companion PMIC - both controlled from same GPIO bank. Use Value: Reduces pick-and-place count by one component vs. dual-SOT23 solution; 0.95 mm height allows ultra-thin enclosure integration. |
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-Q | NPN/NPN configuration; identical R1 = 4.7 kΩ, same SOT363 package and AEC-Q101 rating. | Used where two high-side switches or parallel current boosting is required instead of complementary drive. | Select when dual sourcing (not sourcing+sinking) is needed - e.g., driving two LEDs anode-to-rail. |
| PUMB3H-Q | PNP/PNP configuration; no R1/R2 resistors (both open); requires external base biasing. | Suitable for high-side switching with precise current control via external resistors, not for plug-and-play digital logic. | Choose only if adjustable gain or custom biasing is mandatory; adds two external resistors and layout complexity. |
Compared with PUMD6H-QF, PUMH7H-Q offers matched NPN characteristics for parallel switching but lacks complementary output capability, while PUMB3H-Q sacrifices integration for flexibility - making PUMD6H-QF optimal for fixed-function digital interface where space, cost, and qualification are prioritized.

FAQ
What is the function of R2 being 'open' in PUMD6H-QF?
R2 is unconnected (open) on the PNP transistor (TR2), meaning no internal base resistor is present - TR2 requires external base biasing or direct drive from a logic source capable of sinking current. This preserves design flexibility for PNP-side control while retaining integrated bias on the NPN side (TR1) for simplified digital interfacing.
Can PUMD6H-QF replace BC847 and BC857 simultaneously in a circuit?
Yes - its integrated NPN/PNP pair with GND1/GND2 separation and dedicated I1/O1 and I2/O2 terminals replicates the functional behavior of a BC847 (NPN) + BC857 (PNP) pair. The built-in 4.7 kΩ R1 on TR1 eliminates one external resistor, reducing component count and improving assembly yield in digital switching applications.
Is thermal derating required above 25 °C ambient?
Yes - total device power dissipation drops linearly from 360 mW at 25 °C to zero at 125 °C ambient (per Fig. 1), based on Rth(j-a) = 417 K/W. At 85 °C ambient, maximum allowable Ptot is ~215 mW. Layout must include adequate copper pour and avoid thermal islands to maintain 175 °C junction limit.
Does PUMD6H-QF support 1.8 V logic-level drive on I1 and I2?
Yes - TR1's VI(on) is 0.88 V (typ) and VI(off) is 585 mV (typ), ensuring reliable turn-on with 1.8 V GPIOs. TR2 has no internal resistor, so I2 must be actively pulled low or driven to <0.7 V to ensure cutoff; a 10 kΩ external pull-down is recommended for robust 1.8 V compatibility.
