Product details
Overview
ES2DH from Taiwan Semiconductor is a 2A, 200V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES2DH datasheet, ES2DH pinout, ES2DH application, or ES2DH equivalent, key selection criteria include repetitive peak reverse voltage (200V), surge current rating (50A), junction-to-lead thermal resistance (20°C/W), moisture sensitivity level (J-STD-020 Level 1), and halogen-free compliance per IEC 61249-2-21.
Technical Context
The ES2DH operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability under thermal cycling and humidity stress. Its 35ns trr enables high-frequency switching in DC-DC converters up to several hundred kHz without excessive switching loss.
Designed for automotive-grade environments, ES2DH supports continuous operation from –55°C to +150°C junction temperature, with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse voltage the device blocks reliably in circuit |
| IF | 2 A - average forward current rating at TA = 75°C, defining continuous conduction capability |
| IFSM | 50 A - peak surge current tolerance for 8.3ms half-sine wave, critical for inrush/freewheeling transients |
| trr | 35 ns - measured reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables >1 MHz switching efficiency |
| VF @ 2A, 25°C | 0.95 V - forward voltage drop determining conduction loss and thermal dissipation at rated load |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; defines heat transfer path to PCB copper for thermal design |
| MSL | Level 1 - no floor life limitation before reflow; supports standard SMT assembly without dry pack |

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-ES2D-M3/5BT | Same DO-214AA package, 200V VRRM, 35ns trr, but VF = 0.92V (typ) at 2A; MSL Level 1 confirmed | Identical automotive and industrial use cases; minor VF advantage improves light-load efficiency | Select for marginally lower conduction loss where layout allows same footprint |
| ON Semiconductor ES2D | 200V VRRM, 2A IF, trr = 35ns, but not AEC-Q101 qualified; VF = 0.95V (max) | Suitable for industrial DC-DC and consumer power supplies; not recommended for automotive safety-critical modules | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with VS-ES2D-M3/5BT and ES2D, ES2DH provides guaranteed AEC-Q101 qualification and identical electrical specs except for slightly higher VF tolerance-making it the preferred choice for automotive lighting and ECU snubbers where reliability validation is mandatory.

FAQ
What is the maximum junction temperature rating for ES2DH?
The ES2DH has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This allows operation in under-hood automotive environments and high-density power supplies. Derating curves confirm usable average forward current down to 1.2A at 125°C ambient. The ES2DH's thermal performance remains stable within this range when mounted on adequate copper area per DO-214AA layout guidelines.
Is ES2DH pin-compatible with other parts in the ES2xH family?
Yes, all ES2xH devices-including ES2AH through ES2JH-share identical DO-214AA (SMB) package dimensions, anode/cathode terminal locations, and polarity marking. The ES2DH differs only in VRRM (200V) and associated electrical parameters; mechanical mounting and PCB footprint are fully interchangeable across the family.
Does ES2DH require special handling due to moisture sensitivity?
No-ES2DH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking or dry-pack storage prior to reflow. This simplifies SMT line integration and eliminates moisture-related popcorning risk during standard lead-free reflow profiles.
What is the reverse leakage current specification for ES2DH at elevated temperature?
At TJ = 125°C and rated VR = 200V, ES2DH exhibits a maximum reverse leakage current (IR) of 350 µA, per electrical specifications table. This value is critical for low-power standby circuits and snubber networks where leakage-induced voltage drift must be minimized.
Can ES2DH replace slower rectifiers like 1N4007 in automotive designs?
No-ES2DH is not a drop-in replacement for general-purpose rectifiers like 1N4007. While both are diodes, ES2DH is a super fast recovery device (trr = 35ns) optimized for switching applications, whereas 1N4007 has trr > 2 µs and is unsuitable for frequencies above ~1 kHz. Using ES2DH in place of 1N4007 requires verifying layout parasitics and thermal interface, but ES2DH delivers superior performance in any automotive DC-DC or freewheeling application originally specifying slow rectifiers.
