Product details
Overview
ES1HLH from Taiwan Semiconductor is a 1A, 500V super fast surface-mount rectifier diode in Sub SMA package, featuring 1.70V max forward voltage at 1A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive use in freewheeling and snubber circuits.
For engineers reviewing the ES1HLH datasheet, ES1HLH pinout, ES1HLH application, or ES1HLH equivalent, key selection criteria include its 500V VRRM, 30A IFSM, Junction-to-lead thermal resistance of 35°C/W, moisture sensitivity level 1 rating, and suitability for DC-DC converters requiring low-profile, high-efficiency rectification.
Technical Context
The ES1HLH is a single-die, glass-passivated silicon junction rectifier optimized for high-speed switching with minimal reverse recovery charge. Its 35ns trr and 8pF junction capacitance support efficient operation in 100kHz–1MHz power conversion topologies.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and operates across –55°C to +150°C junction temperature range, with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - Maximum repetitive reverse voltage; defines safe blocking capability in 400V DC bus applications |
| IF | 1 A - Continuous forward current rating; supports sustained conduction in compact 1A power rails |
| IFSM | 30 A - Non-repetitive surge current (8.3ms half-sine); handles inrush and transient overloads without failure |
| VF @ 1A, 25°C | ≤1.70 V - Forward voltage drop; determines conduction loss (1.7W max at 1A) and thermal load in PCB layout |
| trr | ≤35 ns - Reverse recovery time; enables high-frequency switching with low switching loss and EMI |
| RθJL | 35 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper for passive thermal management |
| Junction Capacitance | 8 pF @ 1MHz, 4V - Low capacitance minimizes displacement current and improves high-frequency noise immunity |
Pinout & Package
Package: Sub SMA - Low-profile surface-mount package with cathode band marking, UL 94V-0 molding compound, and matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side (e.g., switch node in buck converter); requires adequate copper pour for thermal dissipation |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive); critical for polarity-sensitive placement in automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, HAST, and UHST - enables use in under-hood modules without additional qualification |
| Glass passivated chip junction | Provides hermetic protection against humidity and contamination, extending operational life in harsh environments (e.g., engine control units) |
| Moisture Sensitivity Level 1 | No floor life limitation or baking required before reflow - simplifies SMT line integration and reduces handling overhead |
| Low profile Sub SMA package | Height ≤1.1mm - allows placement beneath low-clearance shields or in space-constrained modules such as LED drivers and body control units |
| Halogen-free (IEC 61249-2-21) | Complies with RoHS and automotive material declarations - supports end-of-life recycling and regulatory reporting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES1EHE3/5BT | Same Sub SMA package, 1A/500V, but trr = 50ns (vs. 35ns), VF = 1.75V max | Slightly higher switching loss in >500kHz designs; suitable where trr margin is relaxed | Prefer ES1HLH when minimizing EMI or optimizing efficiency above 300kHz |
| ON Semiconductor MUR150 | Through-hole DO-41, 1A/50V - not voltage-compatible; different package and VRRM | Only viable in low-voltage legacy designs; incompatible with 500V blocking or SMT assembly | Select ES1HLH for new automotive or high-density SMT designs requiring 500V rating and AEC-Q101 compliance |
Compared with VS-ES1EHE3/5BT, ES1HLH delivers faster recovery (35ns vs. 50ns) and tighter VF spec (≤1.70V), improving efficiency in high-frequency DC-DC stages; versus MUR150, ES1HLH enables modern SMT manufacturing and meets automotive reliability standards absent in legacy through-hole parts.

FAQ
What is the maximum junction temperature rating for ES1HLH?
The ES1HLH has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version A2103. This rating enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves confirm usable current capacity down to 0.5A at 125°C ambient with appropriate PCB copper area. The ES1HLH must not exceed this limit during steady-state or transient conditions.
Is ES1HLH pin-compatible with other devices in the ES1xLH family?
Yes - all ES1xLH devices, including ES1HLH, share identical Sub SMA package dimensions, pinout (anode/cathode), and mounting footprint per TSC's package outline drawing. Voltage variants differ only in internal die construction and marking code (EHL). No PCB redesign is needed when substituting within the family, though electrical validation for VRRM, VF, and trr remains essential per application requirements.
Does ES1HLH require moisture preconditioning before reflow soldering?
No - ES1HLH is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and does not require baking prior to reflow. This eliminates handling steps in high-volume SMT lines and reduces risk of popcorning or delamination. The ES1HLH's glass passivation and robust molding compound contribute to this MSL-1 classification.
What is the reverse leakage current specification for ES1HLH at elevated temperature?
Per TSC's electrical specifications table, ES1HLH exhibits ≤100 µA reverse leakage current (IR) at rated VR and TJ = 125°C. At 25°C, leakage is ≤5 µA. This low, thermally stable leakage supports reliable blocking in high-temperature automotive applications such as engine control modules, where thermal runaway must be avoided. The ES1HLH maintains this performance without derating up to its 150°C TJ limit.
Can ES1HLH be used as a direct replacement for ES1GLH in an existing design?
ES1HLH and ES1GLH share identical package, pinout, and thermal specs, but differ in VRRM (500V vs. 400V) and VF (≤1.70V vs. ≤1.30V). Substituting ES1HLH for ES1GLH is electrically safe - higher voltage rating adds margin - but may increase conduction loss slightly. Verify system-level stress margins and thermal performance with the ES1HLH's higher VF before deployment. The ES1HLH remains a valid drop-in option where 500V blocking is beneficial.
