Product details
Overview
ES3H from Taiwan Semiconductor is a 3 A, 500 V super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 1.70 V max forward voltage at 3 A and 35 ns reverse recovery time. It serves as a high-efficiency freewheeling or output rectifier in switching-mode power supplies for telecom and computing infrastructure.
For engineers reviewing the ES3H datasheet, ES3H pinout, ES3H application, or ES3H equivalent, key selection criteria include its 500 V repetitive peak reverse voltage, 100 A surge rating, 150 °C maximum junction temperature, thermal resistance of 12 °C/W (junction-to-lead), and compatibility with automated SMT placement per J-STD-020 Level 1 moisture sensitivity.
Technical Context
This single-die silicon rectifier uses a glass-passivated PN junction to achieve super-fast recovery (trr ≤ 35 ns) under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions. Its 500 V VRRM rating and 350 V VR(RMS) support high-voltage DC-DC stages in isolated flyback and forward converters.
The device exhibits 30 pF typical junction capacitance at 1 MHz and 4.0 V reverse bias, enabling low capacitive loading in high-frequency switching nodes. Thermal performance is defined by RθJL = 12 °C/W and RθJA = 47 °C/W, supporting continuous 3 A conduction with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - supports input rectification or secondary-side output rectification in 400 V DC bus systems |
| IF | 3 A continuous - rated for sustained conduction in mid-power SMPS outputs up to ~75 W |
| trr | ≤ 35 ns - minimizes switching losses and EMI in 100–500 kHz converters |
| VF (max) | 1.70 V @ 3 A, 25°C - determines conduction loss and thermal rise in high-duty-cycle operation |
| RθJL | 12 °C/W - enables direct thermal path to PCB copper, critical for compact heatsinking |
| IR (max) | 10 µA @ 25°C, 500 V - ensures low leakage in high-impedance hold-up or sensing circuits |
| CJ | 30 pF @ 1 MHz, 4 V - limits displacement current and ringing in fast-switching nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 1.85 V VF max @ 3 A, 30 ns trr, same DO-214AB package | Higher voltage margin but higher conduction loss; suited for 400–600 V DC link designs | Prefer when system requires >500 V reverse blocking headroom or tighter trr tolerance |
| MBR360 | Schottky diode: 60 V VRRM, 0.72 V VF typ @ 3 A, no reverse recovery, but limited to ≤60 V applications | Zero trr eliminates switching loss but cannot replace ES3H in 500 V circuits | Select only for low-voltage (<60 V), ultra-high-efficiency auxiliary rails where reverse voltage is not limiting |
Compared with STTH3L06S and MBR360, ES3H offers optimal balance of 500 V blocking, 1.70 V VF, and 35 ns trr in cost-sensitive, thermally demanding 3 A rectification-making it ideal for telecom and industrial SMPS where voltage rating and recovery speed must coexist without Schottky limitations.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES3H?
The ES3H has a maximum repetitive peak reverse voltage (VRRM) of 500 V, as specified in the absolute maximum ratings table of the N2102 datasheet. This rating defines the highest instantaneous reverse voltage the ES3H can block repeatedly without breakdown under normal operating conditions and is validated across temperature and lifetime stress testing per JEDEC standards.
What is the forward voltage drop of ES3H at 3 A and 25°C?
The ES3H exhibits a maximum forward voltage (VF) of 1.70 V at 3 A forward current and 25°C junction temperature, per the electrical specifications table. This value is measured under pulse conditions (PW = 0.3 ms) and represents the worst-case conduction loss used for thermal design and efficiency calculation in ES3H-based power stages.
Does ES3H have a defined reverse recovery time, and what is its value?
Yes, ES3H has a specified reverse recovery time (trr) of ≤35 ns, tested under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This parameter is critical for minimizing switching losses in high-frequency converters and is confirmed across all production lots per TSC's quality control protocol for the ES3x family.
What package type does ES3H use, and is it RoHS compliant?
ES3H uses the DO-214AB (SMC) surface-mount package with matte tin-plated leads and is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the device carries J-STD-020 Level 1 moisture sensitivity classification for standard reflow processing.
Can ES3H be used as a direct replacement for ES3G or ES3J in an existing design?
No-ES3H is not a direct replacement for ES3G (400 V) or ES3J (600 V), as each variant has distinct VRRM, VF, and CJ values. Substituting ES3H for ES3J risks insufficient reverse voltage margin; substituting for ES3G may increase conduction loss unnecessarily. Always verify voltage derating, thermal performance, and recovery behavior before interchanging ES3x variants.
