Product details

Overview

ES3G M6G from Taiwan Semiconductor is a 400 V, 3 A super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 3 A and 25°C, and 100 A peak surge current capability; used in high-frequency switching mode power supplies for telecom and computing systems.

For engineers reviewing the ES3G M6G datasheet, ES3G M6G pinout, ES3G M6G application, or ES3G M6G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (12 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.

Technical Context

This device is a single-die, unidirectional silicon rectifier optimized for high-efficiency DC/DC conversion where fast switching and low conduction loss are critical. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses in SMPS operating above 50 kHz, while the glass-passivated junction ensures stable performance under thermal cycling.

The DO-214AB (SMC) package provides robust thermal dissipation (R_θJL = 12 °C/W) and mechanical reliability for reflow-soldered board assembly. Polarity is marked by a cathode band; terminals are matte tin-plated and compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Key Specifications

V_RRM	400 V - maximum repetitive reverse blocking voltage without breakdown
I_F	3 A - continuous average forward current at T_L = 75°C
I_FSM	100 A - non-repetitive surge current handling for 8.3 ms half-sine, enabling robust inrush protection
t_rr	35 ns - ultra-fast reverse recovery reduces switching losses in high-frequency converters
V_F	1.30 V max at I_F = 3 A, T_J = 25°C - low conduction loss improves system efficiency
R_θJL	12 °C/W - enables direct heat transfer to PCB copper, supporting compact thermal design
C_J	30 pF at 1 MHz, V_R = 4 V - low junction capacitance minimizes capacitive coupling noise

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L04S	400 V, 3 A, t_rr = 30 ns, VF = 1.25 V @ 3 A, DO-214AB	Slightly faster recovery and lower V_F, but higher cost and limited volume availability	Preferred where <5 ns t_rr reduction justifies premium pricing and supply chain validation
SB340-E3/52T	40 V, 3 A Schottky; V_F = 0.52 V @ 3 A, no reverse recovery, but V_RRM too low for 400 V line	Not suitable for 400 V reverse blocking; only viable in low-voltage secondary-side roles	Valid alternative only in sub-45 V circuits requiring zero Q_rr; not drop-in for ES3G M6G's primary-side use

Compared with STTH3L04S and SB340-E3/52T, ES3G M6G delivers optimal balance of 400 V blocking, 35 ns recovery, and cost-effective SMC packaging for mainstream telecom and server SMPS-whereas STTH3L04S trades marginal speed gain for cost, and SB340-E3/52T fails basic voltage rating requirements.

FAQ

What is the maximum junction temperature rating for ES3G M6G?

The ES3G M6G has a maximum junction temperature (T_JMAX) of +150°C, allowing reliable operation in thermally demanding environments such as enclosed server power supplies and industrial motor drives. This rating is validated across its full operating current range and supports derating curves up to 75°C lead temperature. The ES3G M6G must be mounted on adequate copper area to maintain junction temperature within limits under continuous 3 A load.

Does ES3G M6G have a specified moisture sensitivity level (MSL)?

Yes, ES3G M6G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions (<30°C / 60% RH) without baking prior to reflow. This eliminates pre-bake requirements in standard SMT lines and supports immediate placement after tape-and-reel unpacking. The ES3G M6G's glass passivation and DO-214AB molding compound contribute to this robust MSL rating.

What is the reverse recovery time (t_rr) of ES3G M6G and how is it measured?

The ES3G M6G has a maximum reverse recovery time (t_rr) of 35 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the manufacturer's test circuit. This value reflects its super fast recovery performance, critical for minimizing switching losses in high-frequency converters. The ES3G M6G achieves this via optimized silicon doping and junction design, distinct from standard fast or ultrafast rectifiers.

Is ES3G M6G compatible with lead-free reflow soldering profiles?

Yes, ES3G M6G is fully compatible with standard lead-free reflow profiles (JEDEC J-STD-020), including peak temperatures up to 260°C for 30 seconds. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 molding compound withstands thermal excursions without delamination. The ES3G M6G's DO-214AB package geometry also ensures consistent wetting and coplanarity during reflow.

What does the "M6G" suffix indicate in ES3G M6G?

The "M6G" suffix in ES3G M6G is Taiwan Semiconductor's internal date and factory code: "M6" denotes manufacturing week/year (e.g., 2026), and "G" identifies the fabrication facility. It does not affect electrical specifications-the core device remains ES3G (400 V, 3 A super fast rectifier). All ES3G M6G units share identical absolute maximum ratings, electrical specs, and package dimensions as defined in datasheet version N2102.
