Product details
Overview
ES3CHM6G from Taiwan Semiconductor is a 3A, 300V 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 capability. It serves as a primary output rectifier in high-frequency switching mode power supplies for telecom and computing infrastructure.
For engineers reviewing the ES3CHM6G datasheet, ES3CHM6G pinout, ES3CHM6G application, or ES3CHM6G equivalent, key selection criteria include VRRM = 300V, IF = 3A, trr = 35ns, RθJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly lines.
Technical Context
This single-die, glass-passivated super fast rectifier operates with junction temperatures up to +150°C and supports repetitive peak reverse voltages of 300V. Its low 35ns reverse recovery time minimizes switching losses in high-frequency converters operating above 100kHz.
The device exhibits 10µA maximum reverse leakage at 25°C and 500µA at 100°C, with junction-to-lead thermal resistance of 12°C/W enabling efficient heat transfer to PCB copper. Its matte tin-plated leads comply with J-STD-002 solderability standards.
Key Specifications

|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or forward converter secondary-side rectification |
| IF | 3 A - Continuous average forward current; determines minimum trace width and thermal pad area on PCB |
| trr | 35 ns - Reverse recovery time; enables use in >200 kHz SMPS without excessive switching loss or EMI |
| VF | 0.95 V max @ 3A/25°C - Forward voltage drop; directly impacts conduction loss and thermal design margin |
| RθJA | 47 °C/W - Junction-to-ambient thermal resistance; used with ambient temperature and power dissipation to calculate max junction temperature |
| IFSM | 100 A - Non-repetitive peak surge current; withstands inrush and transient overloads during startup or fault conditions |

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-3EWH03-M3/5BT | VRRM = 300V, trr = 30ns, VF = 0.92V @ 3A - slightly faster and lower VF, same DO-214AB package | Identical mounting and thermal interface; optimized for <200kHz operation where sub-30ns recovery adds marginal benefit | Select when prioritizing lowest possible conduction loss and tighter trr tolerance in volume production |
| ON Semiconductor MUR330 | VRRM = 300V, trr = 50ns, VF = 0.97V @ 3A - slower recovery, identical IF/IFSM, same package | Suitable for ≤150kHz designs; higher trr increases switching loss but reduces EMI sensitivity | Select when EMI filtering simplicity outweighs efficiency gain, or for legacy design continuity |
Compared with VS-3EWH03-M3/5BT and MUR330, ES3CHM6G delivers balanced performance: 35ns trr ensures high-frequency efficiency while maintaining robust surge capability and industrial-grade thermal specs - ideal for new designs targeting 200–400kHz operation with cost-performance optimization.

FAQ
What is the maximum junction temperature rating for ES3CHM6G?
The ES3CHM6G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet N2102. This rating applies across the full operating current range and enables reliable operation in thermally demanding environments such as enclosed server PSUs or under-hood automotive modules. Derating curves confirm usable current down to -55°C ambient.
Does ES3CHM6G have a specified moisture sensitivity level (MSL)?
Yes, ES3CHM6G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and requires no baking prior to reflow. This is confirmed in the FEATURES section of the Taiwan Semiconductor ES3A–ES3J datasheet (Version N2102), supporting immediate use in high-volume automated SMT lines without moisture-related yield risk.
What is the reverse recovery time (trr) test condition for ES3CHM6G?
The reverse recovery time of 35ns for ES3CHM6G is measured under the standardized condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, as specified in the ELECTRICAL SPECIFICATIONS table of the Taiwan Semiconductor datasheet N2102. This test reflects real-world switching behavior in hard-commutated topologies like forward or flyback converters.
Is ES3CHM6G halogen-free and RoHS compliant?
Yes, ES3CHM6G is both RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor ES3A–ES3J datasheet (N2102). The molding compound contains no brominated flame retardants or chlorine-based additives, meeting environmental requirements for CE-marked and green-certified end equipment.
What does the 'H' in ES3CHM6G indicate?
The 'H' in ES3CHM6G denotes the 300V repetitive peak reverse voltage (VRRM) rating within the ES3x family, per Taiwan Semiconductor's ordering code convention documented in the ORDERING INFORMATION section of datasheet N2102. 'ES3A' = 50V, 'ES3B' = 100V, ..., 'ES3H' = 300V, 'ES3J' = 600V - the 'M6G' suffix indicates tape-and-reel packaging (3,000 pcs/reel) and green compound.
