Nexperia USA Inc. PEMD6,115

Overview

PEMD6 from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in SOT666 package, integrating two bias resistors (R1 = 4.7 kΩ, R2 open) for simplified digital switching. It supports 50 V V_CEO, 100 mA output current per transistor, and operates across −65 °C to +150 °C ambient range-used in low-current peripheral drivers and IC input control circuits.

For engineers reviewing the PEMD6 datasheet, PEMD6 pinout, PEMD6 application, or PEMD6 equivalent, key selection considerations include its dual-polarity RET architecture, built-in 4.7 kΩ base resistors, SOT666 ultra-small footprint (1.6 × 1.2 × 0.55 mm), and thermal resistance of 416 K/W (device-level, FR4 PCB).

Technical Context

The PEMD6 integrates one NPN and one PNP transistor with independent base bias networks-each featuring a single 4.7 kΩ input resistor (R1) and no second bias resistor (R2 = open). This configuration enables direct logic-level drive without external base resistors, reducing component count in digital interface stages.

It operates as a matched complementary pair within a single ultra-compact SMT package, supporting bidirectional signal conditioning and level translation. The device's 50 V breakdown ratings (V_CBO, V_CEO) and 100 mA output capability suit 3.3 V/5 V logic interfacing with moderate-voltage loads.

FAQ

What is the function of R2 in the PEMD6?

R2 is not implemented in the PEMD6-it is electrically open (unconnected) per datasheet Table 8. Only R1 (4.7 kΩ) is integrated per transistor channel. This configuration supports standard single-resistor biasing for direct logic-level drive without requiring complex feedback networks or dual-resistor bias arrangements.

Can PEMD6 replace discrete transistors in existing designs?

Yes-PEMD6 can directly replace two discrete transistors plus two base resistors in NPN+PNP configurations. Pin compatibility requires verifying SOT666 layout alignment and confirming that GND1/GND2 separation matches the target PCB's grounding scheme. No changes to drive logic are needed due to identical input impedance and saturation characteristics.

What is the maximum operating temperature for continuous use?

The PEMD6 supports continuous operation up to +150 °C junction temperature (T_j). At ambient temperatures above 25 °C, derating applies: total power dissipation must be reduced linearly beyond 300 mW based on R_th(j-a) = 416 K/W. For example, at T_amb = 85 °C, max P_tot ≈ 225 mW to maintain T_j ≤ 150 °C.

Is PEMD6 qualified for automotive applications?

No-PEMD6 is not automotive-qualified. The datasheet explicitly states it is intended for industrial, computing, and consumer applications. It has not undergone AEC-Q101 stress testing or been characterized for automotive temperature ranges (−40 °C to +125 °C ambient), nor does it include automotive-specific reliability reporting or PPAP documentation.
