Product details

Overview

ES3D_HF from Diodes Incorporated is a surface-mount super fast rectifier diode rated for 200 V repetitive peak reverse voltage, 3.0 A average forward current, and 25 ns maximum reverse recovery time; it features glass-passivated chip construction, low 0.92 V forward voltage at 3.0 A DC, and AEC-Q101 Rev_C qualification for automotive-grade reliability in power conversion stages of DC-DC converters and LED drivers.

For engineers reviewing the ES3D_HF datasheet, ES3D_HF pinout, ES3D_HF application, or ES3D_HF equivalent, key selection criteria include its 25 ns trr for high-frequency switching, 10 °C/W junction-to-lead thermal resistance, RoHS-compliant "Green" SMC package, and AEC-Q101 qualification for under-hood automotive power supplies.

Technical Context

This super fast rectifier employs a planar epitaxial silicon PN junction with glass passivation to achieve rapid carrier recombination and minimize reverse recovery charge. Its 25 ns trr (measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) enables efficient operation in 100–500 kHz SMPS topologies.

The device operates across –55 °C to +150 °C junction temperature range and delivers stable performance under transient surge conditions: 100 A IFSM (8.3 ms half-sine) and 200 A IFSM (1 ms), supported by 41.5 A²s I²t rating for fusing protection.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive blocking voltage without avalanche breakdown; sets upper limit for input voltage in flyback or boost converters.
I_(AV)	3.0 A @ T_L = 110 °C - Continuous DC output current capability with lead temperature derating; defines usable current in PCB-mounted thermal design.
t_rr	25 ns - Measured reverse recovery time under standardized test conditions; enables high-frequency operation with low switching loss.
V_F	0.92 V @ 3.0 A DC - Forward voltage drop determining conduction loss and thermal load in rectification path.
R_thJL	10 °C/W - Junction-to-lead thermal resistance; critical for estimating die temperature rise when mounted on copper pads with soldered leads.
I_R	10 µA @ 200 V, 25 °C - Low leakage ensures minimal standby power loss in offline adapters and battery-isolated systems.
AEC-Q101	Qualified per Rev_C - Confirms robustness for automotive power modules including engine control units and body electronics.

Pinout & Package

ES3D_HF uses the SMC (DO-214AB) surface-mount package: molded plastic case with UL 94V-0 flammability rating, halogen- and antimony-free "Green" construction, and cathode indicated by a color band. Weight is 0.021 g.

Pin/Terminal	Circuit Role	Design Meaning

Cathode	Forward current exit / reverse blocking terminal	Marked with color band; connects to output capacitor or load; sustains 200 V reverse bias with only 10 µA leakage at 25 °C.

Key Features

Feature	Design Value

Applications

Automotive LED Headlamp Driver

Industrial AC-DC Adapter

Use Scenario: High-efficiency synchronous rectification in 48 V–12 V buck-derived LED driver for adaptive front lighting systems.

IC Role / Device Role / Timing Role: Output rectifier handling 3 A continuous current with <25 ns recovery to reduce switching node ringing and EMI filter size.

Use Value: Enables compact heatsinkless design due to 0.92 V V_F and 10 °C/W R_thJL, meeting AEC-Q101 thermal cycling requirements.

Use Scenario: Secondary-side rectification in universal-input 100 W industrial AC-DC power supply operating at 250 kHz.

IC Role / Device Role / Timing Role: Fast-recovery diode replacing standard FR series to cut conduction + recovery losses by ~18% at full load.

Use Value: Achieves >89% efficiency at 230 VAC input thanks to 25 ns t_rr and low 10 µA I_R at elevated temperatures.

USB-C PD Power Delivery Module

Telecom DC-DC Brick

Use Scenario: Output rectification in 20 V/3 A USB-C PD 3.0 buck-boost converter for portable medical devices.

IC Role / Device Role / Timing Role: Surface-mount super fast diode placed directly at output filter to minimize layout parasitics and improve transient response.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600 V V_RRM, 35 ns t_rr, higher V_F (1.15 V @ 3 A)	Better suited for 400 V bus applications; slower recovery increases switching loss above 200 kHz.	Select when higher voltage margin is required over speed; verify thermal design with +0.23 V higher V_F.
ON Semi MUR320	200 V V_RRM, 35 ns t_rr, same I_(AV), non-AEC-Q101	Lacks automotive qualification; suitable for commercial/industrial use only.	Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated.

Compared with STTH3L06S and MUR320, ES3D_HF offers the fastest recovery (25 ns), lowest forward drop (0.92 V), and automotive qualification - making it optimal for space-constrained, high-frequency, and safety-critical power stages where thermal and EMI performance are prioritized.

FAQ

What is the maximum junction temperature for ES3D_HF during continuous operation?

The ES3D_HF has a specified junction temperature range of –55 °C to +150 °C. Under continuous 3.0 A DC operation at T_L = 110 °C, the junction temperature remains within safe limits provided the PCB pad area and copper weight meet minimum thermal relief guidelines per Diodes' SMC mounting recommendations.

Does ES3D_HF support reflow soldering per JEDEC J-STD-020?

Yes - ES3D_HF's SMC package is qualified for lead-free reflow soldering per JEDEC J-STD-020, with a peak temperature of 260 °C for up to 30 seconds. The "Green" halogen-free molding compound ensures stable thermal performance without delamination or cracking during standard profile reflow cycles.

How does the 25 ns reverse recovery time impact EMI in high-frequency SMPS?

A 25 ns t_rr reduces reverse recovery di/dt and associated voltage overshoot at the switching node, lowering high-frequency common-mode noise. This allows smaller Y-capacitors and simpler EMI filters in 300–500 kHz flyback or LLC converters, directly improving CISPR-22 Class B compliance margins.

Is ES3D_HF pin-compatible with other SMC-packaged rectifiers like ES3B or ES3G?

Yes - ES3D_HF shares identical SMC (DO-214AB) mechanical dimensions and anode/cathode terminal layout with ES3B (100 V), ES3G (400 V), and ES3J (600 V). However, electrical parameters differ significantly; substitution requires verification of V_RRM, t_rr, and thermal design against the target application's stress profile.
