Product details
Overview
ES2CA 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 ES2CA datasheet, ES2CA pinout, ES2CA application, or ES2CA 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 designs.
Technical Context
The ES2CA uses a single-die, glass-passivated PN junction optimized for high-frequency switching, with super-fast recovery (trr ≤ 35 ns) enabling efficient operation in SMPS topologies above 100 kHz. Its low-profile DO-214AC package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, allowing sustained 2 A average forward current up to +125 °C ambient when mounted on standard PCB copper. Reverse leakage remains ≤10 µA at 25 °C and ≤350 µA at 125 °C under rated VRRM.

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 same voltage rating | Optimized for automotive-grade thermal cycling; qualified per AEC-Q101 | Preferred where extended temperature cycling or automotive qualification is required |
| MBR2150 | VRRM = 150 V, Schottky architecture, VF = 0.82 V @ 2 A, no reverse recovery - but IR = 1 mA @ 25 °C | Lower conduction loss, but higher leakage limits use in high-temp or high-impedance hold-up circuits | Choose when minimizing VF dominates over leakage or cost; avoid in >100 °C ambient snubbers |
Compared with STTH2R015 and MBR2150, the ES2CA offers balanced trade-offs: lower cost than AEC-Q101 parts, lower leakage than Schottkys, and sufficient speed for 300 kHz SMPS - making it optimal for cost-sensitive industrial DC-DC and lighting designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2CA?
The ES2CA has a VRRM of 150 V, meaning it reliably blocks up to 150 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2102) and applies across the full operating temperature range of –55 to +150 °C.
Does ES2CA have a specified reverse recovery time (trr)?
Yes, the ES2CA has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor ES2AA–ES2JA datasheet and confirms its classification as a super fast recovery rectifier.
What package type does ES2CA use, and is it RoHS compliant?
The ES2CA uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and is fully RoHS compliant and halogen-free per IEC 61249-2-21. The package outline, solderability (per J-STD-002), and moisture sensitivity level (MSL 1) are all documented in the Mechanical Data section of the official datasheet.
What is the forward voltage (VF) of ES2CA at rated current?
The ES2CA exhibits a maximum forward voltage (VF) of 0.95 V at IF = 2 A and TJ = 25 °C. This value is specified in the Electrical Specifications table and reflects typical conduction loss under standard test conditions - critical for calculating power dissipation in high-current rectifier stages.
Can ES2CA replace ES2BA or ES2DA in an existing design?
No - ES2CA (150 V VRRM) is not a drop-in replacement for ES2BA (100 V) or ES2DA (200 V) due to differing reverse voltage ratings. Substitution requires verification of circuit stress margins; using ES2CA where ES2DA was specified risks reverse breakdown, while using it where ES2BA was intended may over-specify voltage capability without benefit.
