Nexperia USA Inc. PEMB14,115

Overview

PEMB14 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT666 package, featuring integrated 47 kΩ input bias resistors and open R2 configuration. It operates as a matched pair of digital switching transistors with −50 V V_CEO, −100 mA I_O, and −150 mV V_CEsat at I_C = −10 mA, used for low-current peripheral interfacing in microcontroller I/O expansion circuits.

For engineers reviewing the PEMB14 datasheet, PEMB14 pinout, PEMB14 application, or PEMB14 equivalent, this device serves as a space-optimized, component-count-reducing replacement for discrete PNP transistor pairs in 3.3 V/5 V logic-level digital control paths - especially where board area, pick-and-place cost, and design simplification are critical.

Technical Context

The PEMB14 integrates two identical PNP transistors sharing no internal connection between bases or collectors - each has its own dedicated 47 kΩ base resistor (R1) and open-circuit R2, enabling independent digital input drive. Its dual-transistor topology supports complementary signal routing without external bias networks.

Designed for DC-switching operation only, it exhibits h_FE ≥ 100 at I_C = −1 mA and V_CE = −5 V, with thermal resistance R_th(j-a) = 416 K/W per device on FR4 PCB, and maximum junction temperature of 150 °C - confirming suitability for sustained low-power digital interface duty cycles.

FAQ

What is the maximum operating temperature for PEMB14?

The PEMB14 has a maximum junction temperature (T_j) of 150 °C and a storage temperature range of −65 °C to +150 °C. Its thermal resistance is 416 K/W per device on FR4 PCB, meaning it can sustain continuous operation at ambient temperatures up to +85 °C when dissipating ≤150 mW - verified under standard reflow-soldered mounting conditions.

Can PEMB14 be used in analog amplifier configurations?

No - PEMB14 is characterized and qualified exclusively for digital switching applications. Its h_FE is specified only at I_C = −1 mA and V_CE = −5 V, and no small-signal parameters (e.g., f_T, g_m, or linearity data) are provided. The integrated bias resistors also prevent conventional biasing schemes required for linear amplification.

Is the R2 terminal truly open, or is it internally tied to ground?

R2 is unconnected - the datasheet explicitly states "R2 = open" in the quick reference data and confirms no internal connection exists. Pin 3 and pin 6 are collector terminals only; pins 1 and 4 are dedicated emitter returns. No internal tie to GND or other nodes is present, allowing full external flexibility for feedback or pull-up networks.

Does PEMB14 support reverse taping or custom reel packaging?

No - PEMB14 is supplied only in standard 4 mm pitch, 8 mm tape-and-reel format with 3000 units per reel (ordering code suffix -115). Reverse taping is not supported for this part number; that option applies only to PUMB14 variants (e.g., -125 suffix), as confirmed in Table 9 of the official Nexperia datasheet.
