Nexperia USA Inc. PEMD30,115

Overview

PEMD30 from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT666 package, rated for 50 V V_CEO, 100 mA output current per transistor, with built-in 2.2 kΩ input bias resistor (R1) and open R2. It integrates complementary switching transistors for bidirectional signal control in space-constrained logic interface and peripheral driver circuits.

For engineers reviewing the PEMD30 datasheet, PEMD30 pinout, PEMD30 application, or PEMD30 equivalent, this device serves as a compact, bias-resistor-integrated alternative to discrete BC847BVN pairs-reducing PCB area, component count, and assembly cost while maintaining defined DC gain (h_FE ≥ 30 at I_C = 20 mA) and low V_CE(sat) (≤ 150 mV).

Technical Context

The PEMD30 integrates one NPN and one PNP transistor sharing no internal connection between bases or collectors-each has independent biasing via dedicated R1 resistors (2.2 kΩ nominal), with R2 unconnected. Both transistors operate under identical absolute maximum ratings: 50 V V_CEO, 100 mA I_O, and 150 °C T_j.

Thermal performance is specified per transistor (R_th(j-a) = 625 K/W) and per device (R_th(j-a) = 416 K/W) on FR4 PCB, supporting reflow-only assembly. Electrical characteristics include V_(BR)CEO ≥ 50 V, h_FE ≥ 30 (I_C = 20 mA, V_CE = 5 V), and C_c ≤ 3 pF (PNP), enabling stable low-power switching up to ~100 MHz.

FAQ

What is the function of R2 in the PEMD30?

R2 is internally open (not connected) in the PEMD30, as confirmed in Table 8 of the datasheet. This configuration allows direct base drive through I1 and I2 with only R1 providing bias-simplifying use in standard logic-level switching where a second resistor is unnecessary. No external connection or termination is required for R2.

Can PEMD30 replace BC847BVN in existing designs?

Yes-PEMD30 serves as a drop-in functional replacement for BC847BVN dual-transistor arrays in low-current peripheral driver applications. It matches the 50 V/100 mA rating and adds integrated 2.2 kΩ bias resistors, eliminating four external components. Layout adaptation is required due to SOT666 vs. SOT363 footprint, but schematic changes are minimal.

Is PEMD30 qualified for automotive applications?

No-per Section 14 of the datasheet, PEMD30 is explicitly marked as non-automotive qualified. It is not tested or warranted for AEC-Q101 stress conditions, temperature cycling, or lifetime reliability in automotive environments. Use in automotive systems requires formal qualification and validation by the end customer.

What is the maximum operating frequency for PEMD30 switching?

The PEMD30 supports switching up to approximately 100 MHz, based on its specified collector capacitance (C_c ≤ 2.5 pF for TR1, ≤ 3 pF for TR2) and typical h_FE roll-off data in Figures 3–6. For reliable 50% duty-cycle square-wave operation, design margins recommend limiting f_SW to ≤ 20 MHz at full 100 mA load to maintain V_CE(sat) stability and thermal safety.
