Product details

Overview

ES2LD from Taiwan Semiconductor is a 2 A, 200 V super fast surface-mount rectifier in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 0.94 V forward voltage at 2 A/25°C, and 50 A surge capability - used for high-frequency freewheeling and SMPS output rectification in telecom power supplies.

For engineers reviewing the ES2LD datasheet, ES2LD pinout, ES2LD application, or ES2LD equivalent, key selection criteria include its 200 V V_RRM, 35 ns trr, thermal resistance (R_θJL = 35°C/W), moisture sensitivity level 1 compliance, and SMB footprint compatibility with automated SMT assembly.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve super-fast switching performance while maintaining robust surge handling. Its 35 ns reverse recovery time and low 25 pF junction capacitance enable efficient operation in 100–500 kHz switching converters.

The device operates across –55°C to +150°C junction temperature range, with thermal design supported by verified R_θJL = 35°C/W and R_θJA = 80°C/W on standard 16 mm × 16 mm PCB copper pads - critical for thermal management in compact power modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse blocking voltage; defines safe operating limit in DC-link or output rectification circuits
I_F	2 A continuous - rated average forward current; determines steady-state power dissipation and heatsink requirements
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables high-frequency operation with low switching loss
V_F	0.94 V max at 2 A / 25°C - directly impacts conduction loss and efficiency in low-voltage output stages
I_FSM	50 A peak (8.3 ms sine) - supports transient overload tolerance during startup or fault conditions
R_θJL	35 °C/W - junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling

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-2EYH02-M3/54	Same DO-214AA package; 200 V V_RRM, 30 ns t_rr, 0.92 V V_F - marginally faster but higher cost	Preferred where <30 ns t_rr is required for >600 kHz designs	Select if tighter timing control needed; verify layout parasitics support faster edge rates
ON Semiconductor MUR220RLG	DO-201AD package (larger); 200 V V_RRM, 35 ns t_rr, 0.97 V V_F; R_θJA = 65°C/W	Suitable for through-hole prototyping or legacy board upgrades	Choose when DO-214AA footprint unavailable; expect 15% higher thermal resistance on same PCB area

Compared with VS-2EYH02-M3/54 and MUR220RLG, the ES2LD offers optimal balance of SMB footprint, 35 ns recovery, and 0.94 V forward drop - making it preferred for space-constrained, high-volume telecom and industrial SMPS where cost and manufacturability are prioritized over marginal speed gains.

FAQ

What is the maximum junction temperature rating for ES2LD?

The ES2LD has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This rating is validated under specified thermal conditions including R_θJL = 35°C/W on standard PCB copper pads. Derating curves in the ES2LD datasheet confirm 2 A continuous current is sustainable up to 110°C ambient when properly mounted.

Does ES2LD support lead-free reflow soldering?

Yes, ES2LD supports lead-free reflow soldering per J-STD-020 requirements. Its matte tin-plated leads and UL 94V-0 molding compound are qualified for peak reflow temperatures up to 260°C. The device carries moisture sensitivity level 1, eliminating pre-bake steps and enabling direct placement into standard SMT lines.

What is the reverse recovery time (t_rr) test condition for ES2LD?

The ES2LD reverse recovery time is 35 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is guaranteed maximum and applies across the full operating temperature range. It reflects performance in typical high-frequency switching scenarios such as SMPS freewheeling paths.

How does ES2LD compare to ES2LG in forward voltage?

At 2 A and 25°C, ES2LD exhibits a maximum forward voltage (V_F) of 0.94 V, whereas ES2LG (400 V version) is rated at 1.30 V max under identical conditions. This 0.36 V difference directly reduces conduction loss by ~38% in low-voltage output stages, making ES2LD preferable for 12–24 V systems where efficiency is critical.

Is ES2LD halogen-free and RoHS compliant?

Yes, ES2LD is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all homogeneous materials meet EU Directive 2011/65/EU requirements. Full compliance documentation is available upon request from Taiwan Semiconductor.
