Product details
Overview
ES2CAHM2G from Taiwan Semiconductor is a 2A, 150V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and 50 A peak surge current - deployed in DC-DC converters and snubber circuits.
For engineers reviewing the ES2CAHM2G datasheet, ES2CAHM2G pinout, ES2CAHM2G application, or ES2CAHM2G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This single-die, unidirectional silicon rectifier uses glass-passivated junction technology to achieve stable switching performance under high-frequency operation. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses in hard-switched topologies.
The device operates with low forward voltage drop (VF ≤ 0.95 V @ 2 A, 25 °C) and exhibits tight reverse leakage control (IR ≤ 10 µA @ 25 °C, rated VR), supporting efficient energy transfer in compact power supplies and lighting drivers.
Key Specifications

| IFSM | 50 A - non-repetitive surge withstand for 8.3 ms half-sine; supports inrush and fault transient handling |
| trr | 35 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour |
| Junction Temp | –55 to +150 °C - operational range compatible with automotive under-hood and industrial ambient 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 |
|---|---|---|---|
| STTH2R015 | VRRM = 150 V, trr = 30 ns, VF = 0.92 V @ 2 A - slightly faster but higher cost | Same footprint not guaranteed; requires layout verification for SMA pad compatibility | Preferred where <30 ns trr is required and cost premium acceptable |
| MBR2150CT | Dual common-cathode Schottky; VF = 0.85 V @ 2 A, no reverse recovery - but VRRM limited to 150 V with higher leakage | Not suitable for high-temperature (>125 °C) or high-voltage transient environments due to IR increase | Consider only for low-TJ, low-noise applications where Schottky advantages outweigh leakage risk |
Compared with STTH2R015 and MBR2150CT, ES2CAHM2G delivers balanced trade-offs: robust 150 V blocking, industry-standard 35 ns trr, and proven reliability in reflow-soldered industrial assemblies - making it optimal for cost-sensitive, thermally demanding power conversion.

FAQ
What is the maximum junction temperature rating for ES2CAHM2G?
The ES2CAHM2G has a maximum junction temperature (TJ) of +150 °C and a minimum of –55 °C. This wide operating range supports deployment in industrial environments with elevated ambient temperatures. Derating curves in the official datasheet specify that average forward current drops to ~1.3 A at 125 °C case temperature. Thermal design must account for RθJL = 20 °C/W to maintain ES2CAHM2G within safe limits under full load.
Does ES2CAHM2G have a halogen-free construction?
Yes, ES2CAHM2G is halogen-free per IEC 61249-2-21 and RoHS compliant. The molding compound and internal materials meet strict environmental standards without compromising mechanical robustness or thermal performance. This makes ES2CAHM2G suitable for green manufacturing programs and export to regions enforcing halogen restrictions. Certification documentation is available upon request from Taiwan Semiconductor.
What is the reverse recovery time specification for ES2CAHM2G?
The reverse recovery time (trr) for ES2CAHM2G is specified as ≤ 35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across production lots and is critical for minimizing switching losses in high-frequency converters. The fast trr directly contributes to reduced EMI generation and improved efficiency in 300–1000 kHz power stages using ES2CAHM2G.
Is ES2CAHM2G suitable for use in automotive applications?
ES2CAHM2G is not AEC-Q101 qualified and is not recommended for safety-critical automotive systems such as engine control or ADAS. However, it may be used in non-safety automotive auxiliary systems (e.g., infotainment power supplies or interior lighting) where ambient temperature and reliability requirements align with its –55 to +150 °C junction rating and J-STD-020 moisture level 1 classification. Always validate ES2CAHM2G in final system-level testing.
What packaging format is available for ES2CAHM2G?
ES2CAHM2G is supplied in tape-and-reel packaging, 7,500 units per reel, compatible with standard automated pick-and-place equipment. The DO-214AC (SMA) package features matte tin-plated leads meeting J-STD-002 solderability requirements. Reel dimensions and orientation follow EIA-481-D standards, and the marking code "ES2CA" appears on the cathode-banded surface of each ES2CAHM2G unit.
