Product details
Overview
ES2HH from Taiwan Semiconductor is a 2A, 500V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.70V max forward voltage at 2A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive use.
For engineers reviewing the ES2HH datasheet, ES2HH pinout, ES2HH application, or ES2HH equivalent, key selection criteria include repetitive peak reverse voltage (500V), junction-to-lead thermal resistance (20°C/W), moisture sensitivity level (J-STD-020 Level 1), and suitability for snubber and freewheeling circuits in high-efficiency DC-DC converters.
Technical Context
This single-die rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C operating temperature range. Its 35ns trr enables high-frequency switching in automotive power supplies and LED drivers without excessive switching loss.
The device supports automated placement with matte tin-plated leads compliant to J-STD-002, and meets UL 94V-0 flammability rating in its SMB molded case. Polarity is marked by cathode band, and weight is 0.090g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage before breakdown |
| IF | 2 A - continuous average forward current under specified thermal conditions |
| trr | 35 ns - time required to transition from conduction to full blocking state |
| VF (max) | 1.70 V @ 2A, 25°C - forward voltage drop impacting conduction loss and thermal design |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pad sizing |
| IR (max) | 350 µA @ 125°C - leakage current affecting standby power in high-temp environments |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node in flyback/freewheeling paths |

IC Role / Device Role / Timing Role: Freewheeling diode handling inductive energy return during MOSFET off-time. Use Value: 35ns trr minimizes reverse recovery charge (Qrr), reducing EMI and improving efficiency above 200 kHz switching. | Use Scenario: Constant-current LED driver for adaptive front lighting systems requiring thermal robustness. IC Role / Device Role / Timing Role: Output rectifier in isolated flyback stage delivering regulated current to LED strings. Use Value: 150°C max junction temperature and AEC-Q101 qualification ensure operation under hood ambient extremes. |

Use Value: Low VF (1.70V) and fast trr enable precise clamping with minimal conduction loss and overshoot control. | Use Scenario: Secondary-side rectification in 24V/48V telecom or industrial power modules. IC Role / Device Role / Timing Role: Main output rectifier in dual-switch forward or LLC resonant converters. Use Value: DO-214AA package allows compact layout; 20°C/W RθJL supports >1.5W dissipation with minimal copper area. |
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-ES2EH | 500V VRRM, 1.55V VF max @ 2A, 35ns trr, same DO-214AA package | Slightly lower VF reduces conduction loss in thermally constrained layouts | Preferred where junction temperature must stay below 135°C under full load |
| ON Semiconductor MUR260 | 600V VRRM, 1.75V VF max @ 2A, 35ns trr, DO-214AC (SMA) package | Higher voltage rating but smaller package increases thermal resistance (RθJA = 100°C/W) | Use only when 600V margin is required and board space is limited |
Compared with VS-ES2EH and MUR260, ES2HH offers balanced trade-offs: identical trr and VRRM to VS-ES2EH but higher VF, and superior thermal performance versus MUR260 due to larger SMB footprint and lower RθJL-making it optimal for automotive and industrial 500V-class rectification where reliability and thermal headroom are prioritized.

FAQ
What is the maximum junction temperature rating for ES2HH?
The ES2HH has a maximum junction temperature (TJMAX) of +150°C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Thermal design must maintain TJ ≤ 150°C using the specified RθJL of 20°C/W and appropriate PCB copper area. The ES2HH datasheet confirms this limit applies across its full voltage range.
Is ES2HH RoHS and halogen-free compliant?
Yes, ES2HH is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor's official documentation states both requirements are met in the ES2xH family, including ES2HH. The molding compound is UL 94V-0 rated, and terminals are matte tin plated to J-STD-002 standards-ensuring environmental compliance and solderability without lead or brominated flame retardants.
What does the marking code 'ES2H' indicate on the ES2HH device?
The marking code 'ES2H' on the ES2HH device identifies it as the 500V variant within the ES2xH family. Per Taiwan Semiconductor's ordering information, 'x' maps to voltage grade: A=50V, B=100V, ..., H=500V, J=600V. The full orderable part number ES2HH includes the 'H' suffix twice-once in base code and once as voltage identifier-to distinguish it from ES2H (non-H-suffix legacy variants).
Can ES2HH replace ES2GH in an existing design?
ES2HH can replace ES2GH if the design requires ≥500V VRRM and can accommodate its higher 1.70V VF (vs. ES2GH's 1.30V). Both share identical DO-214AA package, 35ns trr, and thermal specs. However, increased conduction loss may raise junction temperature-verify thermal margin and efficiency impact. No PCB changes are needed, but system-level validation is recommended due to VF difference.
What is the surge current rating for ES2HH and how is it tested?
ES2HH has a non-repetitive peak forward surge current (IFSM) rating of 50A, tested per JEDEC standard using an 8.3ms single half-sine wave superimposed on rated DC load. This rating applies at TA = 25°C and reflects capability to withstand brief overloads such as inrush or fault conditions. Derating curves in the ES2xH datasheet show allowable IFSM decreases with rising ambient temperature.
