Product details
Overview
ES1JLH from Taiwan Semiconductor is a 1A, 600V super fast surface-mount rectifier diode in Sub SMA package, featuring 35 ns reverse recovery time, 1.70 V forward voltage at 1 A and 25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES1JLH datasheet, ES1JLH pinout, ES1JLH application, or ES1JLH equivalent, key selection criteria include peak reverse voltage (600 V), ultra-fast switching (trr ≤ 35 ns), low-profile Sub SMA packaging, thermal resistance (RθJL = 35°C/W), and automotive-grade reliability per AEC-Q101.
Technical Context
The ES1JLH is a single-die, glass-passivated silicon junction rectifier optimized for high-speed switching in DC-DC converters and automotive power management. Its 600 V VRRM, 30 A IFSM, and 150°C maximum junction temperature support robust operation under transient stress and elevated ambient conditions.
With 8 pF junction capacitance at 1 MHz/4 V and 100 µA reverse leakage at 125°C, the ES1JLH delivers stable high-frequency performance and low standby loss-critical for snubber networks and freewheeling paths where voltage overshoot and energy dissipation must be tightly controlled.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.05 A IF, 50 ns trr, DO-214AA package | Higher trr increases switching loss in >200 kHz designs; larger footprint than Sub SMA | Prefer ES1JLH for space-constrained, high-frequency automotive modules |
| MBR160L | 60 V VRRM, Schottky, 1.0 A IF, 0.45 V VF, Sub SMA | Insufficient voltage rating for 48 V+ systems; no AEC-Q101 qualification | Only suitable for low-voltage (<60 V) non-automotive freewheeling |
Compared with STTH1L06S and MBR160L, the ES1JLH uniquely combines 600 V rating, 35 ns recovery, AEC-Q101 compliance, and Sub SMA footprint-making it the only option among the three qualified for high-reliability, high-frequency automotive power conversion.

FAQ
What is the maximum repetitive peak reverse voltage of the ES1JLH?
The ES1JLH has a maximum repetitive peak reverse voltage (VRRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103). The ES1JLH is the highest-voltage variant in the ES1ALH–ES1JLH series, where "J" explicitly denotes the 600 V grade. It is designed for use in circuits where transient or steady-state reverse voltages may reach this level, such as in 400 V DC bus clamping or flyback snubbers.
Is the ES1JLH suitable for automotive applications?
Yes, the ES1JLH is AEC-Q101 qualified, as explicitly stated in its features list and verified in the official Taiwan Semiconductor documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress testing (uHAST). The ES1JLH is deployed in automotive LED lighting, HVAC motor control, and body electronics where reliability under thermal and vibration stress is mandatory.
What is the forward voltage drop of the ES1JLH at rated current?
The ES1JLH exhibits a maximum forward voltage (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) to avoid self-heating effects. At higher temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but system design should conservatively use the 25°C max value for worst-case power loss calculation.
Does the ES1JLH have a defined reverse recovery time?
Yes, the ES1JLH 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 loss and EMI in high-frequency power converters. The datasheet confirms this value applies specifically to the ES1JLH (and ES1HLH), distinguishing it from lower-voltage variants that share the same trr limit.
What package type does the ES1JLH use, and what are its mechanical highlights?
The ES1JLH uses the Sub SMA package-a low-profile, surface-mount variant of the SMA outline with reduced height and optimized pad layout. Key mechanical attributes include matte tin-plated leads (J-STD-002 solderable), UL 94V-0 flammability-rated molding compound, cathode band polarity marking, and moisture sensitivity level 1 (no bake required before reflow). Its weight is approximately 0.019 g.
