Product details

Overview

IRLD110PBF from Vishay Siliconix is a logic-level N-channel power MOSFET in HVMDIP (4-pin DIP) package, rated for 100 V V_DS, 0.54 Ω R_DS(on) at V_GS = 5 V, 1 A continuous drain current at 25 °C, and 175 °C maximum junction temperature. It serves as a low-cost, machine-insertable switching element in DC-DC converters, LED drivers, and industrial control relays.

For engineers reviewing the IRLD110PBF datasheet, IRLD110PBF pinout, IRLD110PBF application, or IRLD110PBF equivalent, key selection criteria include its logic-level gate drive (V_GS(th) = 1–2 V), repetitive avalanche rating (I_AR = 1 A), 6.1 nC total gate charge, and thermal performance in through-hole mounting with dual-drain thermal path.

Technical Context

This device belongs to Vishay's third-generation power MOSFET family optimized for fast switching and ruggedness in cost-sensitive, low-power applications. Its HVMDIP package integrates dual drain leads for enhanced thermal conduction to the PCB, enabling up to 1 W power dissipation without heatsinking.

The IRLD110PBF features dynamic dV/dt immunity (5.5 V/ns), body diode recovery time of 110–130 ns, and is characterized for operation across -55 °C to +175 °C ambient, supporting designs requiring high reliability under transient stress and elevated temperature environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports input voltages up to 80 V DC in buck converters and motor drive half-bridges
R_DS(on) @ V_GS = 5 V	0.54 Ω - enables <1 W conduction loss at 1 A, suitable for low-duty-cycle switching
Q_g	6.1 nC - determines gate drive strength requirement; compatible with standard logic-level microcontroller outputs
I_D (continuous, T_A = 25 °C)	1 A - defines maximum steady-state load current without forced airflow or heatsink
T_J(max)	+175 °C - allows operation in sealed enclosures or high-ambient industrial environments
E_AS	100 mJ - specifies single-pulse unclamped inductive energy handling capability
R_thJA	120 °C/W - sets thermal rise per watt; requires minimum 1.5 cm² copper pour for safe 1 W operation

Pinout & Package

The IRLD110PBF uses the HVMDIP (High Voltage Mini-DIP) 4-pin through-hole package with dual drain leads (D1/D2) serving as both current paths and thermal anchors to the PCB. Package dimensions: 7.87–8.38 mm length × 7.62–10.79 mm width × 6.86–7.36 mm height; lead pitch 2.54 mm (0.1").

Pin/Terminal	Circuit Role	Design Meaning
D1, D2	Drain (dual parallel)	Carry main current path and conduct heat directly to PCB copper; must be soldered to large thermal pad
G	Gate	Logic-level control input; threshold 1–2 V; requires no level-shifting when driven by 3.3 V or 5 V MCU
S	Source	Reference node for gate drive and current sensing; connects to ground or low-side return path

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) = 1–2 V enables direct interface with 3.3 V/5 V microcontrollers without gate driver ICs
Repetitive avalanche rated	Rated for 1 A repetitive avalanche current (I_AR) - supports robust operation in inductive load switching
Dual drain thermal path	Two parallel drain pins reduce thermal resistance and improve power dissipation in compact layouts
Dynamic dV/dt immunity	5.5 V/ns rating prevents false turn-on during high-speed voltage transients in noisy industrial environments
End stackable package	HVMDIP mechanical design allows vertical stacking of multiple units on 0.1" grid for space-constrained board layouts

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
IRLB8721PBF	Higher V_DS (30 V), lower R_DS(on) (3.3 mΩ), TO-220 package, not logic-level (V_GS(th) = 1.0–2.4 V but optimized for 10 V drive)	Requires gate driver for full enhancement at 3.3 V; better suited for high-current, low-voltage battery systems	Select IRLB8721PBF only if higher current (>20 A) and lower R_DS(on) are critical and gate drive voltage ≥10 V is available.
FQP30N06L	60 V V_DS, 0.028 Ω R_DS(on) at V_GS = 5 V, TO-220, same logic-level compatibility	Higher current rating (30 A pulsed), larger footprint, no dual-drain thermal advantage	Choose FQP30N06L when higher peak current capability is needed and PCB space permits TO-220 mounting.

Compared with IRLD110PBF, IRLB8721PBF offers superior conduction efficiency but lacks native 3.3 V compatibility and through-hole thermal integration, while FQP30N06L delivers higher current capacity in a less thermally optimized package-making IRLD110PBF optimal for compact, logic-driven, medium-power switching where PCB real estate and thermal management are constrained.

FAQ

What is the maximum continuous drain current for IRLD110PBF at 100 °C ambient temperature?

The IRLD110PBF supports 0.70 A continuous drain current at T_A = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the HVMDIP package without heatsinking. At 25 °C ambient, it delivers 1 A continuously. Designers must verify PCB copper area and airflow to sustain target current at elevated temperatures.

Does IRLD110PBF require a gate resistor for reliable switching?

Yes - a gate resistor is recommended for IRLD110PBF to control dI/dt and prevent oscillation, especially in inductive load circuits. Typical values range from 10 Ω to 47 Ω depending on drive strength and EMI requirements. The datasheet references R_g = 12 Ω in switching time tests, confirming its use for stable turn-on/turn-off behavior.

Can IRLD110PBF be used in avalanche mode repeatedly?

Yes - the IRLD110PBF is explicitly rated for repetitive avalanche operation with I_AR = 1 A and E_AR = 0.13 mJ per pulse. This capability is validated under defined conditions (pulse width ≤ 300 μs, duty cycle ≤ 2 %) and enables robust switching into inductive loads without external clamping components.

What is the body diode forward voltage of IRLD110PBF at 1 A and 25 °C?

The body diode forward voltage (V_SD) of IRLD110PBF is 2.5 V maximum at T_J = 25 °C and I_S = 1 A with V_GS = 0 V. This relatively high drop reflects its planar MOSFET structure and confirms the need for external Schottky diodes in high-efficiency synchronous rectifier designs where V_SD contributes significantly to loss.

Is IRLD110PBF RoHS-compliant and lead-free?

Yes - the "PbF" suffix in IRLD110PBF denotes lead-free and RoHS-compliant construction per Vishay's material categorization standard (see doc?99912). The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and is qualified for reflow soldering with peak temperature up to 300 °C for 10 seconds.
