Product details
Overview
PRMH11Z from Nexperia is a dual NPN resistor-equipped transistor (RET) in a DFN1412-6 (SOT1268) package, designed for digital switching and IC input control. It features 50 V VCEO, 100 mA per transistor output current, built-in bias resistors (R1 = 10 kΩ typ., R2/R1 = 1), AEC-Q101 qualification, and 0.5 mm profile-enabling compact automotive and industrial logic interface designs.
For engineers reviewing the PRMH11Z datasheet, PRMH11Z pinout, PRMH11Z application, or PRMH11Z equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, automotive-grade thermal derating data, and direct alternatives to BC847/BC857-based discrete implementations.
Technical Context
The PRMH11Z integrates two matched NPN transistors with monolithically embedded bias networks-R1 (7–13 kΩ) and R2 (R2/R1 = 0.8–1.2)-eliminating external base resistors. Each transistor operates independently with separate emitter (GND1/GND2), base (I1/I2), and collector (O1/O2) terminals.
Its DFN1412-6 package provides 261 K/W per-device thermal resistance on FR4 PCBs and supports reflow soldering with standardized footprint (1.4 × 1.2 mm body, 0.47 mm height). The device meets AEC-Q101 stress requirements for automotive underhood environments up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V max - supports 24 V automotive logic rails with 100 % margin against transients |
| IO | 100 mA per transistor - drives LED indicators, small relays, or microcontroller GPIO loads directly |
| hFE | 30 min at 5 mA IC - ensures reliable saturation with low base drive current |
| R1 | 10 kΩ typical - sets standard 0.5 mA base current at 5 V logic high, simplifying drive design |
| VCE(sat) | 150 mV max at IC = 10 mA / IB = 0.5 mA - minimizes power loss in switching applications |
| fT | 230 MHz typical - enables fast digital switching up to ~10 MHz with clean edges |
| Ptot (per device) | 480 mW at Tamb ≤ 25 °C - allows dual-transistor operation without forced cooling on standard FR4 |
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 six exposed terminals and 0.5 mm maximum height-optimized for space-constrained automotive ECUs and portable industrial controls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1 - must be tied to local ground reference for proper biasing |
| 2 | I1 | Base input for TR1 - accepts standard CMOS/TTL logic levels (VI(on) = 1.8–2.5 V) |
| 3 | O2 | Collector output for TR2 - open-collector switching node, requires external pull-up |
| 4 | GND2 | Emitter connection for TR2 - independent of GND1; enables isolated load referencing |
| 5 | I2 | Base input for TR2 - electrically identical to I1; supports dual independent digital inputs |
| 6 | O1 | Collector output for TR1 - functionally identical to O2; supports dual-channel load switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent transistor channels with integrated R1/R2 bias network per channel - eliminates 4 external resistors vs. discrete BC847 pair |
| AEC-Q101 qualification | Qualified for automotive applications including engine control modules and body electronics - no additional qualification testing required |
| Ultra-low profile (0.5 mm) | Enables stacking under connectors or placement in tight board cavities - critical for ADAS sensor modules and compact ECU designs |
| Thermal enhancement | 261 K/W Rth(j-a) (per device) on FR4 - sustains 100 mA switching at 85 °C ambient without heatsink |
| Standardized footprint | SOT1268 outline with documented reflow pad layout - ensures manufacturability across contract manufacturers using IPC-7351B-compliant tools |
Applications
| Automotive Body Control Module | Industrial PLC Input Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PRMB11 | PNP/PNP complement - identical package and bias ratios but opposite polarity | Required where active-low switching or high-side load control is needed instead of low-side sinking | Select when interfacing with open-drain MCU outputs or driving P-channel MOSFET gates |
| PRMD3 | NPN/PNP configuration - mixed polarity with shared bias network topology | Supports push-pull output stages or level translation between complementary logic families | Choose for bidirectional signal routing or H-bridge pre-driver applications requiring matched turn-on/turn-off timing |
Compared with PRMB11 and PRMD3, the PRMH11Z offers matched NPN characteristics essential for parallel load switching and consistent VI(on)/VI(off) thresholds-making it optimal for multi-channel digital input conditioning where polarity uniformity and timing symmetry are critical.

FAQ
Is PRMH11Z pin-compatible with BC847-based discrete layouts?
No-PRMH11Z uses a 6-pin DFN1412-6 (SOT1268) package with non-standard pin mapping (GND1/I1/O2/GND2/I2/O1), unlike SOT23 or SC-70 discrete transistors. It requires dedicated PCB layout and cannot be drop-in substituted without redesign. Its value lies in eliminating four external resistors-not mechanical compatibility.
What is the maximum continuous current per channel at 85 °C ambient?
At Tamb = 85 °C, derated power dissipation limits continuous IO to approximately 65 mA per transistor based on the 261 K/W Rth(j-a) and 150 °C Tj(max). This is confirmed by Figure 1's per-device power derating curve, which shows ~310 mW available at 85 °C, supporting 65 mA at 150 mV VCE(sat).
Does PRMH11Z support 1.8 V logic-level input drive?
Yes-VI(on) is specified at 1.8 V (min) at IC = 10 mA, and VI(off) is 1.1 V (typ.) at IC = 100 µA. This ensures robust switching with 1.8 V, 3.3 V, and 5 V logic families without level shifters, as verified in Figure 6 and Table 7.
How does the built-in R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 sets the base-to-emitter feedback path that stabilizes DC bias and improves noise immunity. It ensures consistent hFE-independent turn-on and prevents thermal runaway during sustained conduction-critical for automotive applications where ambient temperature swings exceed 100 °C.
