Product details
Overview
ES2JH from Taiwan Semiconductor is a 2A, 600V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.70V max forward voltage at 2A and 35ns reverse recovery time, used for snubber and freewheeling in automotive DC-DC converters.
For engineers reviewing the ES2JH datasheet, ES2JH pinout, ES2JH application, or ES2JH equivalent, key selection criteria include peak reverse voltage rating, forward voltage drop at rated current, thermal resistance, junction capacitance, and AEC-Q101 qualification status for automotive reliability.
Technical Context
The ES2JH operates as a single-die, unidirectional silicon rectifier with glass-passivated junction and cathode-band polarity marking. Its 600V VRRM, 50A IFSM, and 150°C TJMAX support high-voltage transient suppression in switching power stages.
Thermal performance is defined by RθJL = 20°C/W and RθJA = 75°C/W under standard mounting conditions. Junction capacitance is 20pF at 1MHz/4V, enabling stable high-frequency operation in snubber networks.
Key Specifications

|---|---|
| VRRM | 600 V - maximum non-repetitive reverse voltage the device blocks without breakdown |
| IF | 2 A - continuous average forward current capability at 75°C lead temperature |
| VF (max) | 1.70 V @ 2A, 25°C - forward conduction loss directly impacts efficiency in high-frequency rectification |
| trr | 35 ns - ultra-fast recovery minimizes switching losses and EMI in hard-switched topologies |
| CJ | 20 pF @ 1MHz, 4V - low junction capacitance reduces capacitive coupling and improves high-speed turn-off behavior |
| RθJL | 20 °C/W - enables effective heat transfer from junction to PCB pad or heatsink via lead frame |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

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-ES2JHM3/5BT | Same DO-214AA package, 600V VRRM, but 1.55V VF (typ) at 2A - lower conduction loss | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select when automotive qualification is not required and lower VF is prioritized over qualification |
| ON Semiconductor MUR260G | DO-201AD package (larger), 600V VRRM, 35ns trr, but 1.85V VF (max) - higher forward drop | Higher RθJA (100°C/W) limits power density in space-constrained layouts | Select when legacy through-hole compatibility is needed and thermal margin allows larger footprint |
Compared with VS-ES2JHM3/5BT and MUR260G, the ES2JH uniquely combines AEC-Q101 qualification, SMB footprint, and 1.70V VF max - making it optimal for automotive-grade, high-density DC-DC and lighting designs where reliability and board area are jointly constrained.

FAQ
What is the maximum junction temperature rating for ES2JH?
The ES2JH has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the ES2JH datasheet specify that average forward current must be reduced to 1.2A at 125°C ambient with standard PCB copper area. Thermal design must account for RθJL = 20°C/W to maintain safe junction temperatures.
Is ES2JH AEC-Q101 qualified and what does that cover?
Yes, ES2JH is AEC-Q101 qualified per version A2102 of Taiwan Semiconductor's specification. This qualification includes temperature cycling, high-temperature reverse bias (HTRB), highly accelerated stress test (HAST), and electrostatic discharge (ESD) testing per human-body model (HBM) ≥2kV. The qualification applies specifically to the ES2JH variant in DO-214AA packaging and confirms suitability for automotive power electronics, including engine control units and lighting modules.
What is the reverse recovery time (trr) of ES2JH and how is it measured?
The ES2JH has a reverse recovery time (trr) of 35ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the manufacturer's test circuit in Figure 6 of the ES2JH datasheet. This value is typical and guaranteed maximum. The fast trr results from optimized doping and lifetime control in the epitaxial layer, enabling minimal reverse recovery charge (Qrr) in high-frequency switching applications like DC-DC converters.
Does ES2JH have a halogen-free and RoHS-compliant construction?
Yes, ES2JH uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant (2011/65/EU). The matte tin-plated leads meet J-STD-002 solderability requirements, and the entire assembly passes JESD201 Class 2 whisker testing. These material attributes are confirmed in the "Mechanical Data" and "Features" sections of the official ES2JH datasheet revision A2102.
What is the marking code printed on the ES2JH device body?
The ES2JH is marked with "ES2J" on the device body, followed by a green compound indicator (G), date code (YW), and factory code (F) per the marking diagram in the ES2JH datasheet. This 4-character primary marking distinguishes it from other members of the ES2xH family (e.g., ES2A, ES2F) and confirms the 600V VRRM rating. The cathode band is located adjacent to the marking for polarity identification.
