Nexperia USA Inc. PEMB13,115

Overview

PEMB13 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, configured as two independent PNP transistors with integrated bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ. It delivers −100 mA output current per transistor, supports −50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal-level switching applications such as LED driver control and logic-level translation.

For engineers reviewing the PEMB13 datasheet, PEMB13 pinout, PEMB13 application, or PEMB13 equivalent, this device serves as a space- and BOM-optimized replacement for discrete PNP transistor pairs in low-power digital interface circuits requiring guaranteed turn-on/turn-off thresholds and thermal stability up to 150 °C junction temperature.

Technical Context

The PEMB13 integrates two matched PNP transistors with on-chip base bias networks (R1 = 4.7 kΩ, R2/R1 = 10 typ), enabling direct TTL/CMOS-compatible input drive without external resistors. Each transistor operates with VCE(sat) ≤ −100 mV at IC = −5 mA/IB = −0.25 mA and exhibits hFE ≥ 100 at IC = −10 mA/VCE = −5 V.

Its dual-transistor topology supports independent switching paths with shared ground terminals (pins 1 and 4), and its SOT666 package provides 417 K/W per-device thermal resistance on FR4 PCBs - optimized for high-density automotive body electronics and industrial I/O modules where board space and assembly cost are critical.

FAQ

What is the maximum operating temperature for PEMB13 in continuous operation?

The PEMB13 has a maximum junction temperature (Tj) of 150 °C and an ambient temperature range of −65 °C to +150 °C. For continuous operation at full 100 mA per transistor, derating begins above 25 °C ambient per the 417 K/W per-device Rth(j-a) curve - limiting usable ambient to approximately 85 °C at 50 mW per transistor.

Can PEMB13 be used in place of a single PNP transistor without modification?

No - PEMB13 contains two independent PNP transistors with shared ground pins (1 and 4) and cross-connected outputs (pins 3 and 6). Using only one half requires leaving the unused input (pin 2 or 5) open or tied to ground, and the unused output (pin 6 or 3) unconnected; it cannot substitute for a single discrete PNP without circuit redesign.

Is wave soldering supported for PEMB13's SOT666 package?

No - the datasheet explicitly states "reflow soldering is the only recommended soldering method" for PEMB13. Wave soldering is not characterized or guaranteed, and thermal stress from wave profiles may exceed the device's 260 °C peak reflow limit or damage internal die attach integrity.

How does the R2/R1 ratio affect switching behavior in PEMB13?

The R2/R1 ratio of 10 typ sets the effective base current division, determining the transistor's saturation depth and turn-off speed. A higher ratio increases base drive margin but slows turn-off due to stored charge; the 8–12 range ensures reliable saturation at −5 mA load while maintaining t_off < 200 ns across temperature and voltage extremes.
