Nexperia USA Inc. PRMD16Z

Overview

PRMD16Z from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in a DFN1412-6 (SOT1268) package, rated for 50 V V_CEO, 100 mA output current per transistor, and AEC-Q101 qualified for automotive use. It integrates built-in bias resistors (R1 = 22 kΩ typ., R2/R1 = 2.13 typ.) to replace discrete BJT + resistor combinations in digital switching circuits.

For engineers reviewing the PRMD16Z datasheet, PRMD16Z pinout, PRMD16Z application, or PRMD16Z equivalent, this device serves as a space- and cost-optimized solution for IC input control and low-power load switching where board area, component count, and thermal performance in ultra-thin SMT layouts are critical.

Technical Context

This RET integrates one NPN and one PNP transistor with monolithically embedded base bias networks - R1 connects base to input, R2 connects base to emitter - enabling single-resistor drive logic-level interfacing without external pull-up/down components. Each transistor operates independently with separate emitter (GND1/GND2), collector (O1/O2), and base-input (I1/I2) terminals.

The device supports bidirectional signal conditioning: the NPN side switches positive loads with active-high input (VI(on) = 1.1 V typ. at IC = 2 mA), while the PNP side switches negative rails or complements logic with active-low input (VI(on) = −1.1 V typ.). Both transistors share identical V_CEO = 50 V, I_O = 100 mA, and h_FE ≥ 80 (V_CE = 5 V, I_C = 5 mA).

FAQ

What is the maximum operating temperature for PRMD16Z in continuous use?

The PRMD16Z has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −55 °C to +150 °C. When mounted on a standard FR4 PCB, its power derating curve (Fig. 1) shows usable dissipation drops to 0 mW above +125 °C ambient - so continuous operation is rated up to +125 °C with appropriate thermal design.

Can PRMD16Z replace BC847/BC857 transistor pairs in existing designs?

Yes - PRMD16Z directly replaces one BC847 (NPN) and one BC857 (PNP) plus their four external bias resistors. Pin mapping differs (DFN1412-6 vs. SOT-363), so PCB layout must be updated, but schematic logic remains identical: I1/O1/GND1 replicate BC847 connections; I2/O2/GND2 replicate BC857 connections.

Is the R1 resistor value fixed or adjustable per unit?

R1 is monolithically integrated and fixed at 22 kΩ (typical), with guaranteed min/max of 15.4 kΩ and 28.6 kΩ per device. It is not user-adjustable; variation is process-controlled and documented in Table 4 and Table 7 of the datasheet - no trimming or external tuning is supported.

Does PRMD16Z support 1.8 V logic-level input drive?

Yes - VI(on) is specified at 1.1 V (NPN) and −1.1 V (PNP) with I_C = 2 mA, well within 1.8 V logic high/low thresholds. VI(off) is 0.5 V / −0.5 V, ensuring robust noise margin. Test data (Figs. 6–7) confirms reliable turn-on down to 1.8 V supply with full 100 mA output capability.
