Product details
Overview
PRMH9Z 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 integrates two matched NPN transistors with built-in bias resistors (R1 = 10 kΩ typ., R2/R1 = 4.7 typ.), rated for 50 V VCEO, 100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PRMH9Z datasheet, PRMH9Z pinout, PRMH9Z application, or PRMH9Z equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC847/BC857 pairs in level-shifting, load switching, and microcontroller interface circuits where thermal performance (Rth(j-a) = 261 K/W per device) and ultra-thin profile (0.47 mm height) are critical.
Technical Context
The PRMH9Z integrates two independent NPN transistors on a single die with monolithically trimmed base bias networks-R1 (7–13 kΩ) and R2 (calculated via R2/R1 ratio of 3.7–5.7)-enabling direct logic-level drive without external resistors. Each transistor operates with VCEO = 50 V, IO = 100 mA, and hFE ≥ 100 at IC = 5 mA.
Its DFN1412-6 package features thermal enhancement via exposed paddle and supports reflow soldering per JEDEC J-STD-020. The device meets AEC-Q101 stress requirements including HTGB, HTRB, and temperature cycling, confirming suitability for under-hood automotive modules and industrial control interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum collector-emitter voltage - enables safe operation in 24 V automotive and 3.3/5 V logic interface applications with margin. |
| IO | 100 mA continuous output current per transistor - supports driving LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 10 kΩ typical bias resistor - sets base current for predictable turn-on with standard CMOS/TTL outputs (e.g., 3.3 V GPIO). |
| R2/R1 | 4.7 typical ratio - defines internal feedback network for stable saturation and reduced sensitivity to hFE variation across temperature. |
| Ptot (per device) | 480 mW at Tamb ≤ 25 °C - allows dual-transistor operation within thermal limits on FR4 PCBs without heatsinking. |
| fT | 230 MHz typical transition frequency - ensures adequate bandwidth for PWM switching up to ~10 MHz with low propagation delay. |
| VCE(sat) | 100 mV max at IC = 5 mA, IB = 0.25 mA - minimizes conduction loss and self-heating during sustained on-state operation. |
Pinout & Package
PRMH9Z uses the DFN1412-6 (SOT1268) leadless plastic package: 1.4 mm × 1.2 mm × 0.47 mm body, 0.5 mm max height, thermally enhanced with exposed paddle. Pin numbering follows top-side marking orientation with pin 1 index area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for transistor TR1 - common reference node for first switch channel. |
| 2 | I1 | Base input for TR1 - accepts logic-level signals directly; internal R1 pulls up to VCC. |
| 3 | O2 | Collector output for TR2 - high-side switching node for second channel load connection. |
| 4 | GND2 | Emiter connection for transistor TR2 - independent ground return for second switch channel. |
| 5 | I2 | Base input for TR2 - electrically isolated from I1; enables independent control of both transistors. |
| 6 | O1 | Collector output for TR1 - primary switching node; shares no internal connection with O2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET integration | Reduces PCB area by >60% vs. two discrete BC847 + four bias resistors; eliminates 4 placement steps. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40 °C to +150 °C) and reliability stress tests including HTGB and temperature cycling. |
| Ultra-thin 0.47 mm profile | Enables use in space-constrained modules such as camera actuators, sensor hubs, and slim ECUs where Z-height is limited. |
| Thermally enhanced DFN | 261 K/W junction-to-ambient resistance on FR4 - improves power handling over standard SOT-363 packages by ~25%. |
| Matched R2/R1 ratio | 4.7 ±1.0 typ. - ensures consistent saturation behavior between channels, simplifying timing-critical dual-switch designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | Discrete dual NPN in SOT-363; no built-in resistors - requires 4 external bias resistors. | Higher BOM count and layout complexity; lower thermal efficiency (Rth(j-a) ≈ 350 K/W). | Preferred only when design requires adjustable base bias or mixed PNP/NPN pairing. |
| UMX2N | Same DFN1412-6 package but with R1 = 47 kΩ and R2/R1 = 1 - optimized for higher-voltage logic (5 V/12 V) drive. | Lower input sensitivity; unsuitable for 1.8 V or 3.3 V GPIO without level shifters. | Select when interfacing with legacy 5 V microcontrollers or industrial PLC outputs. |
Compared with BC847BDW1T1G and UMX2N, PRMH9Z offers optimal balance of low-voltage drive capability (VI(on) = 0.8 V min), tight R2/R1 matching, and automotive-grade reliability in the smallest footprint - making it ideal for next-gen compact, high-reliability digital interface designs.

FAQ
What is the maximum operating temperature for PRMH9Z in continuous use?
The PRMH9Z is rated for continuous operation from −55 °C to +150 °C ambient temperature, with a maximum junction temperature of 150 °C. Derating begins above 25 °C ambient per the 261 K/W thermal resistance curve; at 85 °C ambient, maximum continuous power drops to ~300 mW per device.
Can PRMH9Z be used with 1.8 V logic inputs?
Yes - VI(on) is specified at 0.8 V minimum (typ. 1.4 V) at IC = 1 mA, enabling reliable turn-on from 1.8 V GPIOs with sufficient base current. However, full 100 mA output requires verifying VCC ≥ 3.3 V due to R1 voltage drop; for 1.8 V systems, confirm IC ≤ 20 mA using the VI(on) vs. IC curve (Fig. 6).
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio (3.7–5.7) sets internal base-emitter feedback, stabilizing VBE and reducing dependence on hFE variation. A higher ratio increases saturation depth and lowers VCE(sat), but extends turn-off time; PRMH9Z's 4.7 typ. balances speed (<150 ns toff) and low-loss operation (100 mV max VCE(sat)).
Is the DFN1412-6 package compatible with standard reflow profiles?
Yes - the DFN1412-6 (SOT1268) package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Recommended footprint matches Nexperia's sot1268_fr drawing (1.41 mm × 0.71 mm solder lands, 0.35 mm stencil aperture), and thermal pad must be connected to PCB ground plane for optimal Rth(j-a).
