Product details
Overview
PRMD12Z from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in a DFN1412-6 (SOT1268) package, rated for 50 V VCEO, 100 mA output current per transistor, and AEC-Q101 qualified for automotive use. It integrates built-in bias resistors (R1 = 47 kΩ typ., R2/R1 = 1.0) to replace discrete BJT + resistor combinations in digital switching and IC input control circuits.
For engineers reviewing the PRMD12Z datasheet, PRMD12Z pinout, PRMD12Z application, or PRMD12Z equivalent, this device serves as a space- and cost-optimized alternative to BC847/BC857 pairs in low-power logic interfacing, load switching, and automotive body electronics where board area and assembly count are critical.
Technical Context
The PRMD12Z integrates one NPN and one PNP transistor with monolithically embedded base bias networks - R1 (47 kΩ typ.) and R2 (47 kΩ typ.), yielding an R2/R1 ratio of 1.0 - enabling direct logic-level drive without external resistors. Each transistor operates independently with separate emitter (GND1/GND2), base (I1/I2), and collector (O1/O2) terminals.
Its DFN1412-6 package features a 1.4 mm × 1.2 mm × 0.47 mm body and 0.5 mm max height, optimized for thermal performance on FR4 PCBs (Rth(j-a) = 261 K/W per device). The device supports operation from −55 °C to +150 °C ambient and is qualified to AEC-Q101 for automotive under-hood and cabin applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive and 3.3/5 V logic systems with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs without external buffering. |
| hFE | 80 min at VCE = 5 V, IC = 5 mA - Ensures reliable saturation with low base drive; supports 20× overdrive for robust switching. |
| R1 | 47 kΩ typ. - Integrated base resistor eliminates need for external pull-up/down; reduces BOM count by two resistors per channel. |
| R2/R1 | 1.0 typ. - Matched internal resistor ratio ensures symmetrical turn-on behavior for complementary NPN/PNP operation. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot | 480 mW per device at Tamb ≤ 25 °C - Enables higher total power handling than single-transistor RETs, supporting dual-channel operation without derating. |
Pinout & Package
DFN1412-6 (SOT1268) is a leadless, thermally enhanced ultra-thin surface-mount package measuring 1.4 mm × 1.2 mm × 0.47 mm, with exposed thermal pad and 6 terminals. Its low 0.5 mm profile suits space-constrained automotive and portable designs.
| 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); accepts logic-level signals directly without external biasing. |
| 3 | O2 | Collector output for TR2 (PNP); provides active-low switching capability. |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground node enabling floating or split-rail configurations. |
| 5 | I2 | Base input for TR2 (PNP); compatible with 3.3 V/5 V CMOS outputs for bidirectional logic control. |
| 6 | O1 | Collector output for TR1 (NPN); delivers active-high switching with low VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 (47 kΩ) and R2 (47 kΩ) resistors eliminate four external components per pair, reducing layout complexity and placement cost. |
| AEC-Q101 qualification | Validated for automotive applications including body control modules and lighting drivers, with guaranteed operation from −55 °C to +150 °C. |
| Dual complementary topology | Single-package NPN + PNP pairing enables push-pull, level-shifting, and H-bridge pre-driver functions without cross-matching discrete parts. |
| Ultra-small footprint | DFN1412-6 occupies only 1.68 mm² board area - 60% smaller than SOT363 - ideal for compact ECUs and sensor nodes. |
| Low thermal resistance | Rth(j-a) = 261 K/W (per device) allows sustained 100 mA operation on standard FR4 without heatsinking or airflow. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
|
Use Scenario: Driving LED status indicators and small solenoids in door modules and seat controllers. IC Role / Device Role / Timing Role: Dual RET acts as logic-level translator and current amplifier between MCU GPIO and 12 V loads. Use Value: Eliminates need for two separate BJT/resistor sets, reducing component count by 4 and PCB area by 35% versus discrete solutions. |
Use Scenario: Converting 24 V industrial field signals to 3.3 V microcontroller inputs with noise immunity. IC Role / Device Role / Timing Role: PNP side sinks 24 V signal; NPN side buffers into MCU; built-in resistors set precise threshold and hysteresis. Use Value: Achieves <1 µA leakage (ICEO) and 1.2 V VI(off), ensuring stable high-impedance detection even at elevated temperatures. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Sensor Biasing |
|
Use Scenario: Enabling/disabling auxiliary rails (e.g., display backlight, fan) in smart home hubs during boot-up and sleep modes. IC Role / Device Role / Timing Role: NPN/PNP pair provides synchronized active-high and active-low enable signals from a single control line. Use Value: R2/R1 = 1.0 matching ensures matched turn-on timing (<100 ns skew), preventing shoot-through or brown-out during sequencing. |
Use Scenario: Providing precision bias current to photodiode amplifiers and temperature sensor bridges in handheld diagnostics. IC Role / Device Role / Timing Role: PNP transistor sources stable 10–50 µA bias; NPN handles feedback conditioning with low VCE(sat) for minimal offset. Use Value: 80 min hFE and 150 mV VCE(sat) ensure sub-0.1% gain error and <1 µV output drift across −40 °C to +85 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PRMH12 | NPN/NPN complement; identical package and bias values but same polarity; no PNP channel. | Suitable only for dual-sourcing or parallel drive - not for complementary switching or level translation. | Select when needing matched NPN pairs for OR-ing, wired-AND, or redundant signal paths. |
| EMH11 | Same DFN1412-6 package but NPN/PNP with R1 = 100 kΩ, R2/R1 = 0.1; lower hFE (60 min). | Higher input impedance but reduced drive strength; requires stronger logic drive for full saturation. | Prefer for ultra-low standby current (<100 nA ICEO) in battery-powered sensors where speed is secondary. |
Compared with PRMH12 and EMH11, PRMD12Z uniquely delivers balanced NPN/PNP gain, matched bias ratios, and automotive qualification - making it the only choice for space-constrained, safety-aware complementary switching in automotive and industrial control.

FAQ
Is PRMD12Z pin-compatible with BC847/BC857 discrete transistor pairs?
No - PRMD12Z uses a 6-pin DFN1412-6 package with integrated bias resistors and shared ground terminals, whereas BC847/BC857 are individual SOT23 devices requiring external resistors. Layout redesign is required, but net component count drops by four per channel and board area shrinks by >60%.
What is the maximum continuous current per transistor under 85 °C ambient?
At Tamb = 85 °C, the device's per-transistor power derating limits IO to approximately 75 mA (based on Ptot = 480 mW and Rth(j-a) = 261 K/W). This is confirmed by Fig. 1's power derating curve and Table 5's limiting values, ensuring safe operation without forced cooling.
Does PRMD12Z support 1.8 V logic-level input drive?
Yes - VI(on) is specified at 1.6 V min (typ. 3.0 V) for NPN turn-on and 1.2 V min (typ. −1.6 V) for PNP turn-on at IC = 2 mA. At 1.8 V, both transistors achieve full saturation with hFE ≥ 80, verified in Figs. 6 and 13 across −40 °C to +100 °C.
How does the R2/R1 ratio affect switching symmetry between NPN and PNP channels?
An R2/R1 ratio of 1.0 ensures matched base current injection for both transistors under identical input conditions, resulting in <100 ns propagation skew and simultaneous turn-on/turn-off. This symmetry is critical for push-pull drivers and avoids shoot-through in half-bridge configurations.
