Product details

Overview

IRFD214PBF from Vishay Siliconix is a 250 V, 0.45 A N-channel power MOSFET in HVMDIP (4-pin DIP) package, featuring 2.0 Ω R_DS(on) at V_GS = 10 V, 8.2 nC total gate charge, and repetitive avalanche rating-designed for low-power switching in AC-DC auxiliary supplies, relay drivers, and solid-state load switches.

For engineers reviewing the IRFD214PBF datasheet, IRFD214PBF pinout, IRFD214PBF application, or IRFD214PBF equivalent, key selection criteria include its 1 W power dissipation capability, dual-drain thermal path, fast 7.0 ns turn-on delay, and ±20 V gate-source voltage tolerance in through-hole automated assembly environments.

Technical Context

This N-channel enhancement-mode MOSFET uses planar silicon technology optimized for ruggedness and ease of paralleling. It supports unclamped inductive switching with 57 mJ single-pulse avalanche energy and operates reliably from −55 °C to +150 °C junction temperature.

The device integrates a body diode with 190–390 ns reverse recovery time and 0.64–1.3 μC Q_rr, enabling moderate-speed freewheeling in flyback and buck-derived topologies where synchronous rectification is not required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	250 V - supports input voltages up to 170 VAC RMS or 200 VDC bus in auxiliary power stages
R_DS(on)	2.0 Ω max at V_GS = 10 V - delivers ≤0.41 W conduction loss at 0.45 A continuous drain current
Q_g	8.2 nC - enables efficient 100 kHz–500 kHz switching with standard CMOS gate drivers
I_D (cont)	0.45 A at T_A = 25 °C - suitable for sub-watt control loads without heatsinking
E_AS	57 mJ - withstands unclamped inductive energy transients in relay coil or solenoid drive
R_thJA	120 °C/W - limits junction rise to ~120 °C at 1 W dissipation in still air, confirming no forced cooling needed

Pinout & Package

HVMDIP (High Voltage Mini-DIP) package: 4-pin through-hole, 0.1" pin pitch, dual-drain leads (pins 1 & 4) serving as thermal and electrical connection points; case material is thermoset plastic with internal copper leadframe.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Drain)	Main drain terminal	Electrically and thermally connected to die drain; used with Pin 4 for parallel current sharing and enhanced heat transfer to PCB copper
Pin 2 (Gate)	Control electrode	Receives logic-level or 10 V gate drive; ±20 V absolute rating allows robust noise margin in industrial environments
Pin 3 (Source)	Reference node	Serves as return path for load current and gate drive reference; internal source inductance LS = 6.0 nH affects high-dI/dt ringing
Pin 4 (Drain)	Main drain terminal	Identical function and connection to Pin 1; dual-drain configuration reduces effective R_DS(on) parasitic and improves thermal spreading

Key Features

Feature	Design Value
Repetitive avalanche rated	Enables reliable operation under inductive turn-off stress without external snubbers in relay/solenoid drivers
Dynamic dV/dt rating	4.8 V/ns minimum ensures immunity to false turn-on during high-slew-rate voltage transients
End stackable DIP format	Allows vertical stacking of multiple units on same PCB footprint for space-constrained control boards
Low Q_gd/Q_g ratio	4.5/8.2 ≈ 55% - reduces Miller-induced switching instability and improves controllability at high dV/dt
Simple drive requirements	Threshold voltage 2.0–4.0 V enables direct drive from microcontroller GPIO or optocoupler outputs

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP1NK60ZFP	600 V V_DS, 1 A I_D, TO-92 package, higher R_DS(on) (7.5 Ω), no avalanche rating	Higher voltage headroom but lower current and no ruggedized transient handling	Select when >250 V blocking is required and avalanche immunity is not critical
IRFL4310TRPBF	100 V V_DS, 1.4 A I_D, SOT-223, 0.25 Ω R_DS(on), surface-mount only	Lower voltage rating but superior conduction efficiency and thermal performance in compact layouts	Select for higher-current, lower-voltage DC-DC or motor control where PCB space is constrained

Compared with STP1NK60ZFP and IRFL4310TRPBF, the IRFD214PBF uniquely balances 250 V capability, through-hole manufacturability, and built-in avalanche ruggedness-making it optimal for cost-sensitive, reliability-critical auxiliary power and electromechanical interface circuits where leaded assembly and transient resilience are mandatory.

FAQ

What is the maximum continuous drain current for IRFD214PBF at 100 °C ambient temperature?

The IRFD214PBF supports 0.29 A continuous drain current at T_A = 100 °C, derated linearly from 0.45 A at 25 °C using the specified 0.0083 W/°C factor. This reflects thermal limitations of the HVMDIP package in still air, not device degradation. The IRFD214PBF maintains safe operation within its 150 °C maximum junction temperature limit under these conditions.

Does IRFD214PBF require a gate resistor for basic switching operation?

A gate resistor is recommended for the IRFD214PBF to control dI/dt and suppress ringing caused by its 6.0 nH internal source inductance and PCB layout parasitics. While not strictly required for DC on/off, a 10–25 Ω resistor optimizes switching speed and EMI in typical 100 kHz applications. The IRFD214PBF's 8.2 nC Q_g makes it compatible with standard logic drivers without external amplification.

Can IRFD214PBF be used in place of a mechanical switch for 24 V DC loads?

Yes-the IRFD214PBF is routinely deployed as a solid-state replacement for SPST mechanical switches driving 24 V DC resistive or inductive loads up to 0.45 A. Its 250 V V_DS, avalanche rating, and 2.0 Ω R_DS(on) ensure reliable make/break operation with no contact wear or arcing. The IRFD214PBF's dual-drain thermal path further enhances longevity in repeated switching cycles.

Is IRFD214PBF suitable for use in automotive applications?

The IRFD214PBF is not AEC-Q101 qualified and lacks automotive-specific qualification data such as HTOL or ESD testing per ISO 10605. While its −55 °C to +150 °C operating range covers most under-hood temperatures, Vishay does not endorse the IRFD214PBF for safety-critical or mission-critical automotive functions. For automotive use, consult Vishay's AEC-Q101-qualified alternatives like SQ-series MOSFETs.

What is the body diode forward voltage of IRFD214PBF at rated current?

The IRFD214PBF body diode exhibits a typical forward voltage of 2.0 V at I_S = 0.45 A and T_J = 25 °C with V_GS = 0 V. This value increases with junction temperature and current-reaching ~2.5 V at 125 °C. The IRFD214PBF's body diode is intended for freewheeling, not primary conduction, and its 190–390 ns t_rr suits moderate-frequency operation.
