NXP Semiconductors PEMB17,115

Overview

PEMB17 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, featuring integrated bias resistors R1 = 47 kΩ and R2 = 22 kΩ, V_CEO = −50 V, I_O = −100 mA per transistor, and DC current gain h_FE ≥ 60 at I_C = −5 mA. It serves as a compact, pre-biased switching pair for digital logic interfacing and low-current peripheral control in space-constrained PCBs.

For engineers reviewing the PEMB17 datasheet, PEMB17 pinout, PEMB17 application, or PEMB17 equivalent, this device is selected for simplified BJT-based level translation, IC input driving, and replacement of discrete PNP pairs where board area and assembly cost reduction are critical - especially in industrial I/O modules and consumer appliance controllers.

Technical Context

This dual PNP RET integrates two matched PNP transistors with on-chip base-emitter bias networks (R1 and R2), eliminating external resistors required for standard BJT switching. Each transistor operates independently with open-base V_CEO = −50 V and collector saturation voltage V_CE(sat) ≤ −150 mV at I_C = −10 mA / I_B = −0.5 mA.

The R2/R1 ratio is tightly controlled (0.37–0.57 typ.), ensuring consistent turn-on behavior across temperature (−40 °C to +150 °C). Input voltage thresholds VI(on) ≤ −2.7 V and VI(off) ≥ −1.7 V support reliable TTL/CMOS-compatible switching without additional level-shifting circuitry.

Key Specifications

Pinout & Package

SOT666 is a 6-lead plastic surface-mounted package (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density routing and reflow soldering only. Its symmetrical pin layout supports dual-transistor symmetry and ground-referenced input/output configuration.

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual PNP resistor-equipped transistor applications.

Compared with PUMB17, PEMB17 offers higher per-device power handling (300 mW vs 200 mW) due to larger SOT666 thermal mass; versus EMB17, it shares identical performance but differs in manufacturer-specific qualification and traceability documentation.

FAQ

Is PEMB17 pin-compatible with PUMB17?

No - PEMB17 uses SOT666 (6-pin, 2.2 mm × 1.35 mm), while PUMB17 uses SOT363 (SC-88, 1.8 mm × 1.3 mm). Pin numbering and physical layout differ: SOT666 has symmetric GND–IN–OUT–GND–IN–OUT arrangement, whereas SOT363 uses a different pin mapping. PCB redesign is required for substitution.

What is the maximum allowable continuous current per transistor?

The absolute maximum DC output current (I_O) per transistor is −100 mA, as specified in Table 6 of the datasheet. Operation above this value risks permanent damage. Derating is recommended above T_amb = 25 °C per the thermal resistance R_th(j-a) = 416 K/W (per device) on FR4 PCB.

Can PEMB17 be used in linear amplifier mode?

No - PEMB17 is characterized and qualified exclusively for switching applications. Its integrated bias resistors and specified parameters (e.g., h_FE min only at I_C = −5 mA, no linearity data) confirm it is not intended for analog amplification. Use discrete transistors like BC857 for linear gain stages.

Does PEMB17 meet AEC-Q101 reliability standards?

While PEMB17 is widely deployed in automotive body electronics, the official Nexperia AEC-Q101 qualification status applies to specific part variants (e.g., "PEMB17-Q" suffix). Standard PEMB17 carries industrial-grade qualification; designers requiring automotive qualification must verify the Q-grade version and its certified test reports separately.
