Product details
Overview
ES1JALH from Taiwan Semiconductor is a 600 V, 1 A super fast surface-mount rectifier diode in Thin SMA package, with 35 ns reverse recovery time, 1.15 V forward voltage at 1.0 A/25°C, and AEC-Q101 qualification for automotive-grade reliability - used in snubber circuits and DC/DC converter freewheeling paths.
For engineers reviewing the ES1JALH datasheet, ES1JALH pinout, ES1JALH application, or ES1JALH equivalent, key selection criteria include peak reverse voltage (600 V), surge current capability (60 A at 1 ms), junction-to-lead thermal resistance (28 °C/W), and low-profile Thin SMA packaging for high-density power layouts.
Technical Context
This super fast rectifier employs a glass-passivated silicon junction optimized for low forward voltage and rapid switching, enabling efficient energy recovery in high-frequency switching topologies. Its 35 ns trr and 15 pF junction capacitance support operation up to several hundred kHz in DC/DC converters.
The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements - confirming suitability for reflow-soldered automotive PCB assemblies without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe operating limit in high-voltage snubber or flyback clamp circuits |
| IF | 1 A continuous forward current - supports compact power stage designs where average current stays ≤1 A |
| trr | 35 ns - enables high-frequency switching with minimal reverse recovery loss in synchronous rectifier auxiliary paths |
| VF @ 1A/25°C | 1.15 V typical - directly impacts conduction loss and thermal rise in 12–48 V DC/DC output stages |
| RθJL | 28 °C/W - allows accurate junction temperature estimation when mounted on 5 mm × 5 mm Cu pad, critical for thermal derating |
| CJ | 15 pF @ 1 MHz / 4 V - limits capacitive coupling noise in high-dv/dt gate-drive or sensing nodes |
| IFSM (1ms) | 60 A - withstands short-duration inrush or fault currents without bond-wire failure in automotive load dump scenarios |
Pinout & Package
Thin SMA package: surface-mount, single-anode/single-cathode configuration with cathode band marking; 0.029 g mass; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); polarity must align with schematic symbol |
| Cathode | Forward current exit point | Marked by visible band; ties to higher-potential rail (e.g., output capacitor positive) - reverse-biased during off-state |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and body electronics |
| Glass passivated junction | Enhances long-term reliability against humidity and contamination in unsealed environments |
| Low profile Thin SMA | Enables ≤1.1 mm board height - critical for space-constrained infotainment and ADAS modules |
| Junction-to-lead thermal resistance (28 °C/W) | Supports direct thermal path to PCB copper, reducing need for external heatsinking in 1 W dissipation scenarios |
| Moisture sensitivity level 1 | Permits standard SMT reflow without pre-bake, lowering manufacturing cost and cycle time |
Applications
| Automotive Engine Control Unit (ECU) | Industrial DC/DC Converter |
|---|---|
Use Scenario: Freewheeling path in 12 V–48 V buck converter supplying microcontroller and sensor rails. IC Role / Device Role / Timing Role: Unidirectional current path during high-side MOSFET off-time; recovers inductive energy from filter choke.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | Same 600 V VRRM, but TO-277 package (higher RθJA = 80 °C/W); VF = 1.25 V @ 1 A | Requires larger PCB area; less suitable for ultra-thin automotive modules | Prefer ES1JALH where board height < 1.2 mm or thermal resistance < 70 °C/W is required |
| ON Semi MUR160 | 600 V VRRM, SMA package, but slower trr = 50 ns; VF = 1.1 V @ 1 A | Higher reverse recovery loss in >200 kHz designs; not AEC-Q101 qualified | Choose ES1JALH for automotive or high-frequency DC/DC where trr ≤ 35 ns and qualification matter |
Compared with STTH1R06S and MUR160, ES1JALH delivers superior thermal performance in thin-profile layouts and certified automotive reliability - making it optimal for space- and qualification-constrained 1 A, 600 V rectification where switching speed and manufacturability are prioritized.

FAQ
What is the maximum junction temperature rating for ES1JALH?
The ES1JALH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official TSC datasheet. This rating applies under steady-state conditions with proper PCB thermal design - such as mounting on a 5 mm × 5 mm copper pad - and enables operation in under-hood automotive environments where ambient temperatures reach 125°C.
Is ES1JALH suitable for use in automotive applications?
Yes, ES1JALH is AEC-Q101 qualified and explicitly listed for automotive applications in its official documentation. It meets JESD201 Class 2 whisker resistance, J-STD-020 Level 1 moisture sensitivity, and operates across –55°C to +150°C junction temperature range - confirming suitability for engine control units, body control modules, and onboard chargers.
What is the reverse recovery time (trr) of ES1JALH and how is it measured?
The ES1JALH reverse recovery time is 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the TSC datasheet. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency DC/DC converters and snubber circuits.
Does ES1JALH have a specified junction capacitance, and what is its value?
Yes, ES1JALH has a typical junction capacitance (CJ) of 15 pF, measured at 1 MHz and VR = 4.0 V. This low capacitance helps minimize high-frequency noise coupling and EMI generation in sensitive power supply feedback paths and gate-drive circuits.
What packaging and reel quantity is offered for ES1JALH?
ES1JALH is supplied in Thin SMA package on tape-and-reel format, with 14,000 units per reel. The package features matte tin-plated leads compliant with J-STD-002 solderability standards and polarity indicated by a cathode band - supporting automated pick-and-place assembly without manual orientation.
