Product details
Overview
ES3HB from Taiwan Semiconductor is a 3A, 600V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 1.11–1.30V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 34pF junction capacitance - optimized for high-frequency switching in compact AC/DC adapters and LED drivers.
For engineers reviewing the ES3HB datasheet, ES3HB pinout, ES3HB application, or ES3HB equivalent, key selection criteria include its 600V VRRM, low thermal resistance (RθJL = 24°C/W), moisture sensitivity level 1 compliance, and verified performance at 125°C junction temperature in SMPS flyback stages.
Technical Context
The ES3HB employs a single-die, glass-passivated silicon junction with super-fast recovery (trr ≤ 35ns), enabling efficient operation in 50–500kHz switching converters. Its low-profile DO-214AA package supports automated placement and meets UL 94V-0 flammability rating.
Thermal design is supported by RθJL = 24°C/W and RθJA = 84°C/W on a 10mm × 10mm Cu pad PCB, while cathode-band polarity marking ensures unambiguous orientation during assembly.
Key Specifications

| VRRM | 600 V - maximum repetitive reverse voltage withstand capability in continuous operation |
| IF | 3 A - average forward current rating at 75°C case temperature |
| trr | ≤ 35 ns - reverse recovery time enabling high-frequency (>200 kHz) converter designs |
| VF @ 1.5A, 25°C | 1.11–1.30 V - forward voltage drop directly impacting conduction loss and thermal load |
| CJ @ 1MHz, 4V | 34 pF - junction capacitance influencing high-frequency switching noise and EMI behavior |
| RθJL | 24 °C/W - junction-to-lead thermal resistance critical for solder-joint reliability under pulsed loads |
| IFSM | 100 A - non-repetitive surge current handling for inrush and fault 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 |
|---|---|---|---|
| Vishay VS-3EYH06-M3/45 | Same DO-214AA package; 3A/600V; trr = 35ns; VF = 1.25V @ 1.5A/25°C | Identical VRRM and thermal specs; slightly higher VF increases conduction loss by ~3% | Preferred where Vishay supply chain alignment or alternate qualification history is required |
| ON Semiconductor MUR360G | DO-201AD (axial); 3A/600V; trr = 35ns; VF = 1.2V @ 1.5A/25°C; RθJA = 65°C/W | Through-hole mounting only; higher thermal resistance limits power density in SMT designs | Applicable only when legacy through-hole layout or mechanical retention is mandatory |
Compared with VS-3EYH06-M3/45 and MUR360G, the ES3HB offers superior thermal performance (RθJL = 24°C/W vs. ≥30°C/W) and lower profile packaging, making it optimal for modern high-density SMT power supplies where board space and thermal management are constrained.

FAQ
What is the maximum junction temperature rating for the ES3HB?
The ES3HB has a maximum junction temperature (TJ) rating of +150°C, validated per absolute maximum ratings table. This allows reliable operation in enclosed environments up to 85°C ambient when mounted on a 10mm × 10mm copper pad, leveraging its RθJA = 84°C/W thermal performance. Derating curves confirm usable current down to 1.2A at 125°C case temperature. The ES3HB must not exceed this limit to maintain long-term reliability.
Does the ES3HB have a specified reverse recovery time, and how is it measured?
Yes, the ES3HB specifies a maximum reverse recovery time (trr) of 35ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the electrical specifications table. This value is confirmed across all production lots and reflects performance at 25°C ambient. The ES3HB's trr remains stable up to 125°C junction temperature, supporting consistent switching behavior in thermally demanding applications.
What is the forward voltage range of the ES3HB at 3.0A and 125°C?
At 3.0A forward current and 125°C junction temperature, the ES3HB exhibits a forward voltage (VF) range of 0.99–1.13V, as documented in the electrical specifications table. This low VF at elevated temperature directly reduces conduction losses and improves thermal stability in high-load LED drivers and adapters. The ES3HB's VF remains within this band across its qualified manufacturing process.
Is the ES3HB compatible with lead-free reflow soldering processes?
Yes, the ES3HB features matte tin-plated leads compliant with J-STD-002 solderability requirements and rated for lead-free reflow profiles (peak temperature ≤ 260°C). Its moisture sensitivity level 1 classification eliminates pre-bake requirements, allowing direct placement into standard JEDEC-compliant reflow ovens. The ES3HB's package integrity and wire bond strength are validated across IPC-J-STD-020 Class 1 conditions.
What does the marking code "ES3HB" indicate on the device body?
The marking code "ES3HB" laser-etched on the ES3HB device body identifies the exact part number per TSC's ordering nomenclature, where "HB" denotes the 600V VRRM variant within the ES3x family. It is accompanied by green compound (G), date code (YW), and factory code (F) per the marking diagram. No additional interpretation or decoding is required - "ES3HB" on the device equals the orderable part ES3HB.
