Product details

Overview

ES2LJH from Taiwan Semiconductor is a 2 A, 600 V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.70 V max forward voltage at 2 A and 35 ns reverse recovery time. It is AEC-Q101 qualified, glass passivated, and designed for automotive DC–DC converters, snubber circuits, and freewheeling applications requiring high efficiency and thermal robustness up to 150 °C junction temperature.

For engineers reviewing the ES2LJH datasheet, ES2LJH pinout, ES2LJH application, or ES2LJH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 50 A surge rating, 35 ns trr, RoHS/halogen-free compliance, and DO-214AA mechanical compatibility with automated SMT placement.

Technical Context

The ES2LJH is a single-die, silicon planar junction rectifier with glass passivation for enhanced reliability under thermal cycling and humidity stress. Its super fast recovery (trr ≤ 35 ns) enables high-frequency switching in DC–DC topologies while minimizing switching losses and EMI generation.

Thermally, it delivers R_θJL = 35 °C/W and R_θJA = 80 °C/W on a 16 mm × 16 mm Cu pad PCB, supporting continuous 2 A conduction at ambient temperatures up to +85 °C without derating when properly heatsinked via lead termination.

Key Specifications

V_RRM	600 V - supports input stages in 48 V automotive systems and industrial 380 V AC-derived rails without breakdown risk
I_F	2 A continuous - sustains steady-state output current in compact DC–DC modules and LED drivers
I_FSM	50 A (8.3 ms half-sine) - withstands inrush and transient surges in motor control and power supply startup
t_rr	35 ns - enables operation up to ~3 MHz switching frequency with low reverse recovery loss
V_F @ 2 A	≤ 1.70 V - limits conduction loss to ≤3.4 W at full load, easing thermal design in sealed enclosures
T_J max	+150 °C - allows deployment in under-hood automotive environments and high-ambient industrial settings
C_J	20 pF @ 1 MHz, 4 V - reduces capacitive coupling noise in high-dv/dt gate-drive snubbers

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-ES2J-M3/5BT	Same DO-214AA package, 600 V V_RRM, but 1.85 V V_F max @ 2 A and 50 ns t_rr	Slightly higher conduction loss and slower recovery reduce efficiency in >1 MHz designs	Acceptable where layout space matches and thermal margin exists; not recommended for high-frequency snubbers
ON Semiconductor MUR260RLG	DO-201AD (axial) package, 600 V, 2 A, 60 ns t_rr, 1.75 V V_F; no AEC-Q101 qualification	Requires through-hole assembly; unsuitable for automotive under-hood due to missing qualification and higher thermal resistance	Only for cost-sensitive industrial non-automotive use with legacy axial footprint

Compared with VS-ES2J-M3/5BT and MUR260RLG, the ES2LJH offers superior high-frequency performance (35 ns vs. ≥50 ns), lower forward voltage, and automotive-grade reliability-making it the preferred choice for space-constrained, thermally demanding, and safety-critical applications.

FAQ

What is the maximum junction temperature rating for the ES2LJH?

The ES2LJH has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version A2102). This rating enables reliable operation in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures exceed 85 °C. The ES2LJH must be mounted on a PCB with adequate copper area to maintain this limit under full 2 A load.

Is the ES2LJH pin-compatible with other parts in the ES2LxH series?

Yes, all ES2LxH variants-including ES2LDH, ES2LGH, and ES2LJH-share identical DO-214AA (SMB) package dimensions, pinout, and thermal pad layout. The only differences are V_RRM (200 V to 600 V) and corresponding forward voltage (0.94 V to 1.70 V). Therefore, the ES2LJH can be used as a drop-in replacement in designs originally specifying lower-voltage versions, provided system voltage margins support 600 V standoff.

Does the ES2LJH require baking before reflow soldering?

No, the ES2LJH has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60% RH and does not require pre-reflow baking. This simplifies SMT line logistics and eliminates moisture-related popcorning risk during reflow. The ES2LJH's glass passivated die and halogen-free molding compound further enhance process robustness.

What is the reverse recovery time (t_rr) specification for the ES2LJH?

The ES2LJH has a maximum reverse recovery time (t_rr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official Taiwan Semiconductor datasheet. This value is confirmed across production lots and is critical for minimizing switching losses in high-frequency DC–DC converters and snubber circuits. The ES2LJH achieves this performance via optimized carrier lifetime control in its silicon epitaxial layer.

Can the ES2LJH be used in non-automotive applications?

Yes, the ES2LJH is fully suitable for industrial, medical, and consumer applications requiring a 2 A, 600 V super fast rectifier-even outside automotive contexts. Its AEC-Q101 qualification provides extra margin for reliability, and features like MSL 1, RoHS/halogen-free compliance, and 150 °C T_J max benefit any high-reliability design. However, the ES2LJH is not rated for life-supporting medical equipment per TSC's notice on page 6.
