Product details

Overview

ES3JHM6G from Taiwan Semiconductor is a 3A, 600V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.70V max forward voltage at 3A/25°C, and 100A peak surge current capability. It serves as a primary output rectifier in high-frequency switching power supplies for telecom and computing infrastructure.

For engineers reviewing the ES3JHM6G datasheet, ES3JHM6G pinout, ES3JHM6G application, or ES3JHM6G equivalent, key selection criteria include V_RRM = 600V, I_F = 3A, t_rr = 35ns, R_θJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly lines.

Technical Context

This device implements a single-die silicon PN junction structure with glass passivated chip junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its super fast recovery characteristic enables efficient operation in 100–500 kHz SMPS topologies where low switching loss and minimal reverse recovery charge are critical.

The DO-214AB (SMC) package provides robust thermal performance (R_θJL = 12°C/W) and matte tin-plated leads compliant with J-STD-002 solderability standards. Polarity is unambiguously indicated by a cathode band, and the device is halogen-free per IEC 61249-2-21.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES3JH-M3/5BT	V_F = 1.75V max @ 3A; t_rr = 35ns; same DO-214AB package; R_θJA = 45°C/W	Slightly higher V_F increases conduction loss by ~30mW at 3A; identical thermal profile	Drop-in replacement if board-level validation confirms thermal margin with 0.05V higher V_F
ON Semiconductor MUR360HE3/A	V_RRM = 600V; t_rr = 50ns; V_F = 1.75V max; DO-201AD package (larger footprint)	Slower recovery increases switching loss in >300kHz designs; requires PCB pad redesign due to different outline	Consider only when DO-214AB footprint is unavailable and frequency <250kHz

Compared with VS-ES3JH-M3/5BT and MUR360HE3/A, ES3JHM6G offers the lowest V_F among 600V/3A super fast rectifiers in DO-214AB, delivering superior thermal efficiency in space-constrained, high-density power modules.

FAQ

What is the maximum junction temperature rating for ES3JHM6G?

The ES3JHM6G has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows operation in sealed industrial enclosures up to +70°C ambient when mounted on standard FR-4 with 1-inch² copper pour. Derating begins above T_L = 75°C per the forward current derating curve.

Does ES3JHM6G support lead-free reflow soldering per JEDEC J-STD-020?

Yes, ES3JHM6G is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles (peak 260°C) without baking. The matte tin-plated leads comply with J-STD-002 for solderability, and the DO-214AB package withstands thermal cycling without delamination or voiding.

What is the reverse leakage current specification for ES3JHM6G at elevated temperature?

At T_J = 100°C and rated V_R, ES3JHM6G exhibits a maximum reverse leakage current (I_R) of 500 µA, as specified in the Electrical Specifications table. At 25°C, I_R is limited to 10 µA. This low leakage supports stable hold-up time in offline capacitors and minimizes standby power loss.

Is ES3JHM6G pin-compatible with other devices in the ES3x family?

Yes, all ES3x devices-including ES3JHM6G-share identical DO-214AB (SMC) package dimensions, pinout, and thermal characteristics. Voltage variants (ES3A–ES3J) differ only in V_RRM and V_F; no PCB layout change is required when substituting within the family for voltage rating verification.

How does the junction capacitance of ES3JHM6G affect EMI in high-frequency converters?

ES3JHM6G has a typical junction capacitance (C_J) of 30 pF at 1 MHz and 4V reverse bias. This low C_J reduces high-frequency displacement current during switching transitions, lowering common-mode EMI generation in 300–500 kHz flyback and LLC converters compared to standard fast rectifiers with >60 pF C_J.
