Product details
Overview
ES2BA from Taiwan Semiconductor is a 2A, 100V 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 - used in DC-DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the ES2BA datasheet, ES2BA pinout, ES2BA application, or ES2BA equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial and lighting power designs.
Technical Context
This single-die, unidirectional silicon rectifier uses glass passivated junction technology to achieve super fast recovery (trr ≤ 35 ns) with low forward voltage drop, enabling high-frequency switching operation in SMPS and inverters. Its DO-214AC package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
The device operates across –55 °C to +150 °C junction temperature, with RθJA = 75 °C/W and RθJL = 20 °C/W, allowing reliable thermal management in compact layouts. 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 |
|---|---|---|---|
| STTH2R01 | VRRM = 100 V, trr = 30 ns, VF = 0.92 V @ 2 A - slightly faster but same package and rating | Optimized for higher-frequency (>200 kHz) PFC stages where sub-30 ns trr reduces EMI | Preferred when minimal reverse recovery tail is critical; requires validation of layout parasitics |
| MBR2100 | Schottky construction, VF = 0.82 V @ 2 A, but VRRM = 100 V max and TJ limited to 125 °C | Lower conduction loss in low-voltage, low-temperature environments; unsuitable for >125 °C ambient | Select only if junction temperature stays below 125 °C and reverse leakage tolerance >100 µA is acceptable |
Compared with STTH2R01 and MBR2100, the ES2BA offers balanced trade-offs: robust 150 °C operation, industry-standard DO-214AC footprint, and consistent 35 ns trr with proven reliability in lighting and industrial converters - making it ideal for cost-sensitive, thermally demanding applications.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2BA?
The ES2BA has a maximum repetitive peak reverse voltage (VRRM) of 100 V, verified per Taiwan Semiconductor's M2102 datasheet. This rating defines the highest reverse voltage the ES2BA can block repeatedly without breakdown under normal operating conditions. Exceeding this value risks avalanche failure or permanent degradation of the junction.
What is the forward voltage drop (VF) of ES2BA at rated current?
The ES2BA exhibits a typical forward voltage drop (VF) of 0.95 V at 2 A forward current and 25 °C junction temperature, as specified in the electrical characteristics table. This value directly impacts conduction losses in power stages; actual VF increases with temperature and decreases slightly at lower currents.
Does ES2BA have a defined reverse recovery time (trr)?
Yes, the ES2BA has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This parameter is critical for minimizing switching losses and EMI in high-frequency converters - and is confirmed in the "ELECTRICAL SPECIFICATIONS" section of the ES2BA datasheet.
What package type does ES2BA use, and is it RoHS compliant?
The ES2BA uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and UL 94V-0 molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official Taiwan Semiconductor documentation for ES2BA.
What is the peak forward surge current (IFSM) rating for ES2BA?
The ES2BA is rated for a peak forward surge current (IFSM) of 50 A, tested with an 8.3 ms single half-sine wave superimposed on rated load. This rating ensures survivability during inrush events or short-circuit transients in power supplies and motor control circuits using the ES2BA.
