Product details
Overview
ES3AHM6G from Taiwan Semiconductor is a 3A, 50V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 3A/25°C, and 100A peak surge current - used for high-frequency freewheeling in switching-mode power supplies.
For engineers reviewing the ES3AHM6G datasheet, ES3AHM6G pinout, ES3AHM6G application, or ES3AHM6G equivalent, key selection criteria include VRRM = 50V, IF = 3A, trr = 35ns, thermal resistance RθJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT placement.
Technical Context
This single-die, glass-passivated super fast rectifier delivers low conduction loss and minimal switching loss in high-frequency DC/DC conversion stages. Its 35ns reverse recovery time and 0.95V typical forward voltage at rated current enable efficient operation in 100–500kHz SMPS topologies.
The device operates across –55°C to +150°C junction temperature range, with moisture sensitivity level 1 (J-STD-020), matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound - supporting robust industrial and telecom power designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse blocking voltage; defines safe operating ceiling in flyback/clamp circuits |
| IF | 3 A continuous - average forward current rating at TL = 75°C; sets thermal design baseline for PCB copper area |
| trr | 35 ns - measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables <500kHz switching without excessive diode switching loss |
| VF (max) | 0.95 V at IF = 3A, TJ = 25°C - directly determines conduction loss and thermal rise in high-duty-cycle applications |
| RθJA | 47 °C/W - junction-to-ambient thermal resistance; used to calculate required heatsinking or copper pour for 3A steady-state operation |
| IFSM | 100 A - non-repetitive peak surge current (8.3ms half-sine); supports inrush and transient overload tolerance in AC-DC front ends |
| CJ | 45 pF at 1MHz, VR = 4V - junction capacitance impacts EMI filtering and snubber design in high-dv/dt environments |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode indicated by band, matte tin-plated leads, weight ≈ 0.210g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck/flyback); polarity critical for correct rectification |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or positive bus; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in IPC Class 2 environments |
| Super fast recovery (35ns) | Reduces reverse recovery charge (Qrr) and associated switching losses vs. standard fast rectifiers - critical for >200kHz converters |
| Moisture sensitivity level 1 | Allows unlimited floor life before reflow; eliminates bake requirements and simplifies SMT line logistics |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - required for CE-marked industrial and telecom equipment |
Applications
| Server Power Supply | Telecom DC-DC Converter |
|---|---|
Use Scenario: Output rectification in 48V input, 12V/30A isolated forward converter. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; handles 3A average forward current with minimal voltage drop.

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-3EYH01-M3/5BT | VRRM = 100V, trr = 35ns, VF = 1.05V @ 3A - higher VRRM, slightly higher forward drop | Preferred where 100V blocking margin is needed (e.g., 48V systems with transients) | Select when system requires ≥100V VRRM; not drop-in due to different marking and minor VF increase |
| ON Semiconductor MUR320RLG | VRRM = 200V, trr = 35ns, VF = 0.92V @ 3A - higher VRRM, marginally lower VF | Suitable for 24V/48V systems with elevated line transients or wider input ranges | Choose for 200V-rated designs; same trr, but larger footprint (DO-201AD) requires layout change |
Compared with ES3AHM6G, VS-3EYH01-M3/5BT offers higher voltage margin at slight conduction loss cost, while MUR320RLG provides broader voltage headroom in a larger package - both require layout review and are not pin-compatible replacements.

FAQ
What is the maximum junction temperature rating for ES3AHM6G?
The ES3AHM6G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in enclosed industrial enclosures and telecom base station power modules where ambient temperatures exceed 85°C. Derating curves in the ES3A–ES3J datasheet confirm 3A continuous current is sustainable up to 75°C lead temperature.
Is ES3AHM6G compatible with lead-free reflow soldering processes?
Yes, ES3AHM6G supports lead-free reflow per JEDEC J-STD-020. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated Class 1 - meaning unlimited floor life before reflow. The DO-214AB package withstands peak reflow temperatures up to 260°C for 10 seconds without delamination or parametric shift.
What does the 'HM6G' suffix indicate in ES3AHM6G?
The 'HM6G' suffix in ES3AHM6G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'H' indicates halogen-free compound, 'M6' specifies tape-and-reel packaging (3,000 units per reel), and 'G' confirms RoHS-compliant finish. This matches the ordering code structure defined in the ES3A–ES3J datasheet Version N2102.
How does ES3AHM6G compare to standard fast recovery rectifiers in switching loss?
ES3AHM6G achieves 35ns reverse recovery time versus 100–200ns in standard fast rectifiers, reducing reverse recovery charge (Qrr) by ~60%. In a 300kHz flyback converter, this cuts diode switching loss by approximately 0.3W at 3A, directly improving full-load efficiency and easing thermal management on the secondary-side PCB.
Can ES3AHM6G be used in place of a Schottky rectifier?
ES3AHM6G is not a Schottky diode and should not replace Schottky rectifiers in low-voltage (<20V) outputs due to its higher 0.95V forward voltage. However, it is preferred over Schottky devices in 50V+ applications where Schottky leakage (e.g., >100µA at 100°C) and temperature instability would compromise reliability - such as in 48V telecom power rails.
