Product details
Overview
ES2JALH from Taiwan Semiconductor is a 2 A, 600 V super fast surface-mount rectifier diode in a Thin SMA package, featuring 35 ns reverse recovery time, 1.24 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES2JALH datasheet, ES2JALH pinout, ES2JALH application, or ES2JALH equivalent, key selection factors include its 600 V repetitive peak reverse voltage, low-profile Thin SMA footprint, 1.70 V max VF at 2 A/25°C, and junction-to-lead thermal resistance of 24 °C/W for thermal management in high-density DC/DC converters.
Technical Context
The ES2JALH is a single-die, glass-passivated silicon rectifier optimized for high-speed switching with controlled reverse recovery (trr ≤ 35 ns) and low junction capacitance (21 pF at 1 MHz/4 V). Its design targets minimal power loss in repetitive commutation applications where voltage standoff and thermal robustness are critical.
It operates across –55°C to +150°C junction temperature range, supports surge currents up to 120 A (1 ms), and meets J-STD-020 moisture sensitivity level 1-enabling compatibility with standard reflow processes without baking requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES2JHM3/5BT | Same 600 V VRRM, 2 A IF, but TO-277 package (higher RθJA = 90 °C/W) | Larger footprint; less suitable for ultra-thin consumer designs | Prefer when higher surge rating (IFSM = 150 A) is prioritized over board space |
| ON Semiconductor MUR260 | 600 V VRRM, 2 A IF, but DO-214AC package and slower trr (≈50 ns) | Higher switching loss; not AEC-Q101 qualified | Acceptable for cost-sensitive industrial non-automotive use where AEC-Q101 is not required |
Compared with VS-ES2JHM3/5BT and MUR260, the ES2JALH delivers superior thermal performance in minimal area via Thin SMA, maintains automotive qualification, and achieves faster recovery-making it optimal for space-constrained, thermally demanding, and automotive-grade applications.

FAQ
What is the maximum junction temperature rating for ES2JALH?
The ES2JALH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm usable forward current down to 1.2 A at 100°C ambient when mounted on a standard 5 mm × 5 mm Cu pad. The ES2JALH must not exceed this limit during steady-state or transient conditions.
Is ES2JALH pin-compatible with other parts in the ES2xALH series?
No-ES2JALH shares the same Thin SMA package and pinout (anode/cathode) with all ES2xALH variants (e.g., ES2BALH, ES2DALH), making them mechanically interchangeable. However, electrical parameters differ significantly: VRRM ranges from 100 V to 600 V across the series, and VF increases with voltage rating. Substituting ES2JALH for a lower-voltage variant may overdesign, while substituting a lower-voltage part risks breakdown. Always verify voltage and thermal requirements before replacement.
Does ES2JALH require pre-baking before reflow soldering?
No, ES2JALH does not require pre-baking prior to reflow soldering because it is rated at moisture sensitivity level (MSL) 1 per J-STD-020. This means the device can be stored indefinitely at ≤30°C/60% RH and exposed to ambient conditions without absorption risk. Standard lead-free reflow profiles (peak 260°C) are fully supported, simplifying manufacturing flow and eliminating bake-related yield loss or delay.
What is the reverse recovery time (trr) specification for ES2JALH?
The ES2JALH reverse recovery time is specified as ≤35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured at 25°C and represents the maximum time required for the device to transition from conduction to blocking state. The fast trr minimizes switching losses and voltage overshoot in high-frequency converters, directly contributing to improved system efficiency and reduced EMI generation in designs using the ES2JALH.
How does the forward voltage of ES2JALH vary with temperature?
The ES2JALH forward voltage decreases with rising junction temperature: at 2 A, VF is 1.24 V (typ) at 25°C but drops to 1.01 V (typ) at 125°C. This negative temperature coefficient helps balance current sharing in parallel configurations and reduces conduction loss at elevated operating temperatures. The datasheet provides full VF vs. TJ curves, confirming stable behavior across the –55°C to +150°C range. Designers should use the 125°C data point for worst-case thermal analysis of the ES2JALH.
