Product details
Overview
ES1JH from Taiwan Semiconductor is a 1A, 600V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 1.70V max forward voltage at 1A and 35ns reverse recovery time, used for freewheeling and snubber circuits in automotive lighting and DC-DC converters.
For engineers reviewing the ES1JH datasheet, ES1JH pinout, ES1JH application, or ES1JH equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 35°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification for automotive reliability.
Technical Context
This discrete diode operates as a single-die, unidirectional super fast recovery rectifier with glass passivated junction and matte tin-plated leads. Its 600V VRRM, 30A IFSM, and 35ns trr enable high-frequency switching efficiency in flyback and clamp topologies.
Designed for automated SMT placement, it meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; case material complies with UL 94V-0.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES1JH?
The ES1JH has a maximum repetitive peak reverse voltage (VRRM) of 600 V. This rating defines the highest reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. It is confirmed in the Absolute Maximum Ratings table of the Taiwan Semiconductor ES1AH–ES1JH datasheet (Version B2112), and directly distinguishes ES1JH from lower-voltage variants like ES1AH (50 V) or ES1GH (400 V).
Is ES1JH qualified for automotive applications?
Yes, ES1JH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock-ensuring reliability in automotive under-hood environments. The ES1JH's –55°C to +150°C junction temperature range and moisture sensitivity level 1 further support its suitability for automotive lighting and power modules.
What is the forward voltage drop (VF) of ES1JH at rated current?
The ES1JH exhibits a maximum forward voltage drop (VF) of 1.70 V at 1 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects conduction loss during normal operation. At elevated temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but the 1.70 V max remains the design-limiting specification for thermal and efficiency calculations.
What package type does ES1JH use, and is it RoHS compliant?
ES1JH uses the DO-214AC (SMA) surface-mount package, with matte tin-plated leads and UL 94V-0 compliant molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the FEATURES section of the Taiwan Semiconductor datasheet. The package supports automated placement and meets J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
What is the reverse recovery time (trr) of ES1JH, and why does it matter?
The ES1JH has a reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultra-fast recovery minimizes stored charge (Qrr) and associated switching losses in high-frequency power supplies and motor drives. In practice, this enables efficient operation in DC-DC converters switching above 100 kHz and reduces EMI generation compared to standard or fast recovery diodes.
