Product details
Overview
ES1CHM2G from Taiwan Semiconductor is a 1 A, 150 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A, and 5 µA reverse leakage at 25°C, used in DC-DC converters and snubber circuits.
For engineers reviewing the ES1CHM2G datasheet, ES1CHM2G pinout, ES1CHM2G application, or ES1CHM2G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), forward surge current rating (30 A), junction-to-lead thermal resistance (35 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve super-fast switching performance with low forward voltage drop and minimal reverse recovery charge. Its DO-214AC (SMA) package supports automated placement and meets UL 94V-0 flammability requirements.
The device operates across -55°C to +150°C junction temperature range, with 85 °C/W junction-to-ambient thermal resistance and 35 °C/W junction-to-lead thermal resistance. Reverse recovery time is specified at 35 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions.
Key Specifications

| VRRM | 150 V - peak repetitive reverse voltage sets maximum blocking capability in flyback or snubber applications |
| trr | 35 ns - ultra-fast reverse recovery enables high-frequency switching (>100 kHz) with reduced switching losses |
| VF @ 1 A | 0.95 V - low forward voltage minimizes conduction loss and thermal stress in compact power stages |
| IR @ 25°C | 5 µA - low leakage ensures stable DC bias integrity in high-impedance sensing or hold-up circuits |
| RθJL | 35 °C/W - efficient junction-to-lead heat transfer supports reliable operation without heatsinking at ≤1 A |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR115 | VRRM = 150 V, trr = 35 ns, VF = 0.93 V @ 1 A, same DO-214AC package | Identical electrical specs; slightly tighter VF distribution and higher production volume | Preferred where supply chain redundancy and extended lifecycle support are required |
| Vishay VS-1EWH01-M3/5AT | VRRM = 100 V, trr = 25 ns, VF = 0.87 V @ 1 A, DO-214AC package | Lower VRRM limits use to ≤100 V systems; faster trr benefits >500 kHz designs | Select only when system VR does not exceed 100 V and sub-30 ns recovery is critical |
Compared with MUR115 and VS-1EWH01-M3/5AT, ES1CHM2G offers balanced trade-offs: full 150 V blocking with industry-standard 35 ns trr and proven J-STD-020 Level 1 manufacturability-ideal for cost-sensitive, high-volume industrial power supplies.

FAQ
What is the maximum junction temperature rating for ES1CHM2G?
The ES1CHM2G has a maximum junction temperature (TJ MAX) of +150°C, enabling reliable operation in high-ambient environments such as enclosed industrial power supplies or LED driver enclosures. This rating is validated per JEDEC JESD22-A108 and supported by its 35 °C/W junction-to-lead thermal resistance. Derating begins above 125°C ambient per the forward current derating curve in the ES1A–ES1J datasheet.
Does ES1CHM2G meet RoHS and halogen-free requirements?
Yes, ES1CHM2G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These attributes are verified in TSC's material declarations and confirmed on the official Taiwan Semiconductor product page for ES1CHM2G.
What is the reverse recovery time specification for ES1CHM2G and how is it tested?
The reverse recovery time (trr) of ES1CHM2G is 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standard test conditions. This value is typified across production lots and appears in the Electrical Specifications table of the ES1A–ES1J datasheet. It reflects actual switching behavior in high-frequency DC-DC converters using ES1CHM2G as a freewheeling diode.
Is ES1CHM2G compatible with lead-free reflow soldering processes?
Yes, ES1CHM2G supports lead-free reflow soldering with peak temperatures up to 260°C. Its J-STD-020 moisture sensitivity level is Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking. Matte tin-plated leads ensure wetting performance per J-STD-002, and the UL 94V-0 molding compound withstands thermal excursions.
How does the forward voltage of ES1CHM2G compare to other 150 V super fast rectifiers?
ES1CHM2G exhibits a typical forward voltage of 0.95 V at 1 A and 25°C, matching industry benchmarks for 150 V super fast rectifiers like ON Semiconductor's MUR115. This VF value remains stable across temperature and current, contributing to predictable conduction loss in ES1CHM2G-based power stages without requiring complex thermal compensation.
