Vishay Siliconix IRLD014

Overview

IRLD014 from Vishay Siliconix is a logic-level N-channel power MOSFET in HVMDIP (4-pin DIP) package, rated for 60 V V_DS, 0.20 Ω R_DS(on) at V_GS = 5 V, 1.7 A continuous drain current at 25 °C, and 175 °C maximum junction temperature - designed for low-cost, machine-insertable DC-DC converter and motor control stages requiring robust avalanche capability (490 mJ) and fast switching.

For engineers reviewing the IRLD014 datasheet, IRLD014 pinout, IRLD014 application, or IRLD014 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), dual-drain thermal path for 1 W dissipation, dV/dt ruggedness (4.5 V/ns), and HVMDIP stackability on 0.1" pitch PCBs.

Technical Context

The IRLD014 is a third-generation planar VDMOS device optimized for automatic insertion and thermal management via dual-drain configuration. Its gate threshold voltage (1.0–2.0 V) ensures full enhancement with 3.3 V or 5 V logic drivers, while its 8.4 nC total gate charge supports efficient high-frequency switching up to several hundred kHz.

Designed for unclamped inductive switching, the IRLD014 delivers 490 mJ single-pulse avalanche energy under defined test conditions (V_DD = 25 V, L = 197 mH, I_AS = 1.7 A). Its body diode exhibits 93–130 ns reverse recovery time and 0.34–0.65 μC Q_rr, enabling moderate-speed freewheeling in flyback and half-bridge topologies.

FAQ

What is the maximum continuous drain current for IRLD014 at 100 °C ambient temperature?

The IRLD014 supports 1.2 A continuous drain current at T_A = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the HVMDIP package with natural convection cooling. At higher ambient temperatures, further linear derating applies at 0.0083 W/°C beyond 100 °C, and actual current capability depends on PCB copper area and airflow. The IRLD014 must be mounted with both drain pins soldered to adequate copper pour to achieve this rating.

Does IRLD014 require a gate resistor for typical 5 V microcontroller drive?

Yes - a gate resistor is recommended for the IRLD014 even with 5 V microcontroller drive. While the IRLD014's logic-level gate enables turn-on with 5 V, its 8.4 nC total gate charge and 6.4 nC gate-drain charge make it susceptible to ringing and overshoot without controlled turn-on/off timing. A 10–25 Ω series gate resistor (as used in Vishay's switching test circuits) stabilizes transitions, reduces EMI, and prevents shoot-through in half-bridge configurations. The IRLD014 gate-source leakage remains below ±100 nA, ensuring stable bias once charged.

Can IRLD014 be used in parallel with another IRLD014 for higher current handling?

Yes - the IRLD014 is explicitly designed for end-stacking and parallel operation. Its HVMDIP package allows mechanical stacking of multiple units on 0.1" pin centers, and its positive R_DS(on) temperature coefficient promotes current sharing. For reliable parallel use, ensure matched gate drive paths, symmetrical PCB layout, and shared source return to minimize imbalance. Each IRLD014 contributes ~1.7 A at 25 °C ambient, and the dual-drain configuration helps distribute thermal load across the board. The IRLD014's 175 °C T_J(max) supports coordinated thermal management in stacked arrangements.

What is the body diode forward voltage of IRLD014, and how does it affect freewheeling operation?

The IRLD014 body diode exhibits a forward voltage (V_SD) of 1.6 V at T_J = 25 °C and I_S = 1.7 A with V_GS = 0 V. This relatively high V_SD increases conduction loss during freewheeling compared to Schottky diodes, but enables robust reverse recovery (93–130 ns trr, 0.34–0.65 μC Q_rr). In low-frequency (<50 kHz) inductive switching, the IRLD014 body diode provides adequate flyback path; for higher efficiency, external diode clamping is recommended. The IRLD014's body diode is integral to its safe operating area and avalanche rating.

Is IRLD014 suitable for automotive applications?

The IRLD014 is not AEC-Q101 qualified and is not recommended for safety-critical automotive applications such as engine control or braking systems. However, it is used in non-safety automotive subsystems including interior lighting, HVAC actuators, and accessory power distribution - provided ambient temperature, vibration, and lifetime requirements are validated per application. Its 175 °C T_J(max), 60 V V_DS, and 490 mJ E_AS meet many under-dash environmental demands, but the IRLD014 lacks automotive-grade qualification documentation and extended temperature screening. Always verify compliance with vehicle manufacturer specifications before deploying IRLD014 in automotive designs.
