NXP Semiconductors PMF87EN,115

Overview

PMF87EN from Nexperia is a 30 V, single N-channel Trench MOSFET in SOT323 (SC-70) package, designed for low-side load switching and high-speed line driving. It features logic-level gate drive compatibility (V_GS(th) = 1.5 V typ), R_DS(on) = 67 mΩ at V_GS = 10 V and I_D = 1.7 A, and fast switching with t_d(on) = 3 ns and t_f = 6 ns. It operates reliably in ambient temperatures from −55 °C to 150 °C.

For engineers reviewing the PMF87EN datasheet, PMF87EN pinout, PMF87EN application, or PMF87EN equivalent, this page delivers verified electrical parameters, thermal derating curves, gate charge behavior, and real-world use context for relay drivers, low-side switches, and high-speed digital interface circuits.

Technical Context

The PMF87EN uses Trench MOSFET technology to achieve low R_DS(on) and high transconductance (g_fs = 5.8 S typ), enabling efficient conduction and rapid voltage-controlled switching. Its gate threshold voltage (V_GS(th) = 1.5 V typ) ensures reliable turn-on with standard 3.3 V or 5 V logic outputs.

Dynamic performance is defined by Q_G(tot) = 4.7 nC max and low capacitances (C_iss = 135 pF, C_rss = 14 pF), supporting clean signal integrity in high-frequency switching applications. The device's SOA is validated up to 30 V and 6.8 A peak drain current under pulsed conditions.

FAQ

What is the maximum continuous drain current for PMF87EN at 100 °C ambient temperature?

The PMF87EN supports a continuous drain current of 1.1 A at T_amb = 100 °C, as specified in Table 5 (Limiting values). This derating reflects thermal constraints of the SOT323 package on standard FR4 PCBs and must be applied alongside junction temperature monitoring in thermal design. The PMF87EN datasheet confirms this value under V_GS = 10 V conditions with no heatsink.

Does PMF87EN have avalanche rating or ruggedness specification?

No, the PMF87EN datasheet does not specify unclamped inductive switching (UIS) capability, avalanche energy rating (E_AS), or ruggedness testing. It is rated per IEC 60134 absolute maximum limits only. For inductive load applications like relay driving, external protection (e.g., flyback diode) remains essential. The PMF87EN is not characterized for repetitive avalanche operation.

Can PMF87EN be used with 3.3 V microcontroller GPIO without a gate driver?

Yes-the PMF87EN has a typical V_GS(th) of 1.5 V and guaranteed turn-on at V_GS ≥ 2.5 V, making it fully compatible with 3.3 V logic. At V_GS = 3.3 V, R_DS(on) rises to ~110 mΩ (per Fig. 9), still sufficient for ≤500 mA loads. The PMF87EN's 4.7 nC total gate charge ensures fast enough switching without external buffering in most low-frequency applications.

What is the thermal resistance from junction to solder point (R_th(j-sp)) for PMF87EN?

The PMF87EN has R_th(j-sp) = 60–70 K/W, as listed in Table 6 under "Thermal characteristics." This value applies to devices mounted on FR4 PCBs with single-sided copper, tin-plated, and standard SOT323 footprint. It directly informs solder-point temperature estimation during thermal design and is lower than R_th(j-a), confirming effective heat transfer through the drain pad.

Is PMF87EN suitable for automotive applications?

No-the PMF87EN is not AEC-Q101 qualified and is explicitly designated as a non-automotive qualified product per Nexperia's legal disclaimers. While it operates from −55 °C to +150 °C, it lacks automotive-specific stress testing, failure-in-time (FIT) reporting, and PPAP documentation. For automotive use, alternatives like BSH103,215 should be selected instead of PMF87EN.
