Product details

Overview

ESH3D M6G from Taiwan Semiconductor is a 200 V, 3 A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.9 V max forward voltage at 3 A, and 125 A peak surge capability - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.

For engineers reviewing the ESH3D M6G datasheet, ESH3D M6G pinout, ESH3D M6G application, or ESH3D M6G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (R_θJL = 12 °C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.

Technical Context

The ESH3D M6G is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency DC/DC conversion where fast switching and low conduction loss are critical. Its ultra-fast trr ≤ 20 ns enables operation in 100–500 kHz SMPS topologies without excessive switching losses.

Designed for surface-mount assembly in space-constrained power stages, it supports reflow soldering per J-STD-002, meets UL 94V-0 flammability, and maintains stable reverse leakage (<5 µA @ 25°C, <150 µA @ 125°C) across its full -55°C to +175°C junction temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating margin in 170 VAC input rectification or 150 V bus clamp circuits.
I_F	3 A continuous - Rated average forward current at T_L = 75°C; supports sustained 36 W dissipation in typical PCB layouts.
t_rr	≤20 ns - Measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables minimal switching loss in hard-switched PFC and LLC resonant converters.
V_F	≤0.9 V @ 3 A, 25°C - Low forward drop reduces conduction loss by ~15% vs. standard fast rectifiers, improving efficiency in 12 V/24 V output rails.
R_θJL	12 °C/W - Junction-to-lead thermal resistance; allows direct heat transfer to copper pour or heatsink tab without thermal pad, simplifying thermal design.
C_J	45 pF @ 1 MHz, 4 V - Low junction capacitance minimizes capacitive coupling noise and improves EMI performance in high-dv/dt environments.

Pinout & Package

DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, cathode indicated by band, polarity-critical for series/parallel stacking; weight ≈ 0.200 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unbanded end)	Forward current entry point	Connected to AC input or switch node; must withstand 125 A surge during cold-start inrush.

Key Features

Feature	Design Value
Glass passivated junction	Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial-grade power modules.
Ultra-fast 20 ns recovery	Reduces reverse recovery charge (Q_rr) to <15 nC, lowering diode-induced voltage spikes and snubber losses in synchronous rectifier designs.
MSL 1 rating	Permits unlimited floor life and standard reflow profile use without baking - accelerates NPI ramp and eliminates moisture-related popcorning risk.
Halogen-free & RoHS compliant	Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; required for CE-marked telecom and industrial equipment shipments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EWH02-M3/45	V_RRM = 200 V, t_rr = 25 ns, V_F = 0.95 V @ 3 A - slightly slower recovery and higher forward drop.	Approved for automotive AEC-Q101 but not required in industrial telecom systems.	Preferred where automotive qualification is mandatory; otherwise ESH3D M6G offers tighter t_rr and lower V_F.
ON Semiconductor MUR320	V_RRM = 200 V, t_rr = 35 ns, V_F = 1.05 V @ 3 A - significantly slower and less efficient.	Legacy through-hole TO-220AB package; requires manual assembly or adapter footprint.	Select only if legacy board reuse or through-hole mounting is required; ESH3D M6G delivers superior efficiency and SMT scalability.

Compared with VS-3EWH02-M3/45 and MUR320, the ESH3D M6G provides the lowest combined t_rr/V_F product in DO-214AB, enabling higher-frequency operation and reduced thermal stress in compact power supplies - especially valuable where board area and thermal headroom are constrained.

FAQ

What is the maximum junction temperature rating for the ESH3D M6G?

The ESH3D M6G has a maximum junction temperature (T_J) of +175°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments like enclosed telecom chassis or sealed industrial enclosures. Derating curves confirm usable current capacity down to 1.5 A at 125°C ambient when mounted on 1-inch² 2-oz copper. The ESH3D M6G maintains specified electrical parameters within this full range.

Does the ESH3D M6G meet RoHS and halogen-free requirements?

Yes, the ESH3D M6G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These certifications are confirmed in the official Taiwan Semiconductor datasheet revision I2102 and verified via material declarations from TSC's certified supply chain. The ESH3D M6G carries "G" suffix in marking code to denote green compound, directly indicating halogen-free molding material.

What is the reverse recovery time specification for the ESH3D M6G?

The reverse recovery time (t_rr) for the ESH3D M6G is ≤20 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A. This value is guaranteed maximum and appears in the Electrical Specifications table. The ESH3D M6G achieves this performance via optimized epitaxial layer doping and lifetime control, distinguishing it from standard fast rectifiers like MUR320 (35 ns).

Is the ESH3D M6G suitable for automated SMT assembly?

Yes, the ESH3D M6G is explicitly designed for automated placement and reflow soldering. It features a DO-214AB (SMC) package with matte tin-plated leads compliant with J-STD-002, MSL Level 1 per J-STD-020, and low-profile geometry. The ESH3D M6G has been qualified for standard lead-free reflow profiles (peak 260°C, 60 sec max), and its marking code "ESH3D M6G" supports optical recognition in pick-and-place machines.

How does the ESH3D M6G compare to the ESH3B and ESH3C variants?

The ESH3D M6G shares identical package (DO-214AB), thermal specs (R_θJL = 12 °C/W), and electrical test conditions with ESH3B (100 V) and ESH3C (150 V), differing only in V_RRM and associated VR(RMS) ratings. All three use the same die process and layout. The ESH3D M6G is selected when 200 V blocking is required - for example, in 170 VAC-input systems with 20% line surge margin - while ESH3B/C serve lower-voltage applications.
