Product details
Overview
ES1BHR3G from Taiwan Semiconductor is a 1 A, 100 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A and 25°C, and 30 A peak surge current capability; used for freewheeling and snubber circuits in DC-DC converters.
For engineers reviewing the ES1BHR3G datasheet, ES1BHR3G pinout, ES1BHR3G application, or ES1BHR3G equivalent, key selection criteria include reverse voltage rating (100 V), ultrafast switching performance (trr ≤ 35 ns), thermal resistance (RθJL = 35°C/W), and RoHS/halogen-free compliance for high-efficiency power conversion designs.
Technical Context
This discrete silicon diode employs a glass-passivated junction for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its single-die configuration and DO-214AC package support automated SMT placement and reflow soldering per J-STD-002.
The device delivers low conduction loss (VF = 0.95 V @ 1 A, 25°C) and rapid commutation (trr = 35 ns), enabling high-frequency operation in switching-mode power supplies while maintaining thermal stability up to TJ = 150°C.
Key Specifications

|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage; defines safe blocking capability in 100 V bus applications |
| IF | 1 A - continuous forward current rating; supports steady-state power handling in compact SMPS designs |
| trr | 35 ns - reverse recovery time; enables efficient operation above 100 kHz switching frequencies |
| VF | 0.95 V @ 1 A, 25°C - forward voltage drop; determines conduction loss and thermal load under rated current |
| RθJL | 35 °C/W - junction-to-lead thermal resistance; enables direct heat transfer to PCB copper for passive cooling |
| IFSM | 30 A - non-repetitive peak surge current; withstands inrush and transient overloads in converter startup |

IC Role / Device Role / Timing Role: Output rectifier synchronizing with primary-side PWM controller timing. Use Value: DO-214AC footprint allows dense layout; RθJL = 35°C/W enables thermal coupling to heatsink pad for stable 1 A operation. | Use Scenario: Inductor flyback path in automotive body control module (BCM) buck regulators (12 V → 5 V/3 A). IC Role / Device Role / Timing Role: Unidirectional current path returning stored inductor energy to input rail during switch off-cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | VF = 1.05 V @ 1 A, 25°C; trr = 30 ns; same DO-214AC package | Slightly faster recovery but higher conduction loss; marginally higher thermal resistance (RθJL = 40°C/W) | Prefer when minimizing switching loss dominates over conduction loss in >300 kHz designs |
| MBR1100 | Schottky structure; VF = 0.82 V @ 1 A, 25°C; VRRM = 100 V; trr not applicable | No reverse recovery charge, but higher leakage (IR = 500 µA @ 100 V, 125°C) limits high-temp use | Select for low-noise, low-VF applications below 100°C ambient; avoid in high-temp snubbers |
Compared with STTH1R06U and MBR1100, ES1BHR3G offers the best balance of low VF, ultrafast trr, and high-temperature leakage performance (IR = 100 µA @ 125°C), making it optimal for thermally constrained, medium-frequency industrial power supplies.

FAQ
What is the maximum junction temperature rating for ES1BHR3G?
The ES1BHR3G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules. Derating begins above 25°C ambient per the forward current derating curve in the ES1A–ES1J datasheet. The ES1BHR3G maintains specified electrical parameters within this thermal envelope.
Does ES1BHR3G have a halogen-free construction?
Yes, ES1BHR3G is halogen-free in accordance with IEC 61249-2-21 and RoHS compliant. The molding compound contains no brominated or chlorinated flame retardants, and the matte tin-plated leads meet J-STD-002 solderability requirements. This makes ES1BHR3G suitable for environmentally regulated end equipment including EU consumer electronics and industrial automation systems.
What is the reverse recovery time (trr) test condition for ES1BHR3G?
The reverse recovery time of 35 ns for ES1BHR3G is measured under the condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table. This standardized test reflects real-world commutation behavior in hard-switched topologies. The ES1BHR3G's trr remains stable across temperature and is critical for minimizing switching losses in 100–500 kHz power converters.
Is ES1BHR3G suitable for use in snubber circuits?
Yes, ES1BHR3G is explicitly recommended for snubber applications per its official Applications list. Its 100 V VRRM, 30 A IFSM, and 35 ns trr enable effective clamping of voltage transients across switching devices. The DO-214AC package provides adequate thermal dissipation during short-duration snubber pulses, and the device's low leakage (5 µA @ 25°C) ensures minimal standby loss in RC snubbers.
What does the 'HR3G' suffix indicate in ES1BHR3G?
The 'HR3G' suffix in ES1BHR3G denotes Taiwan Semiconductor's tape-and-reel packaging variant: 'H' = halogen-free, 'R3' = 7,500 pcs per reel, 'G' = green compound (RoHS-compliant molding material). This matches the Ordering Information section specifying ES1x in DO-214AC (SMA) with 7,500/reel packing. The core electrical and thermal specs remain identical to ES1B.
