Product details

Overview

ES3CHR7G from Taiwan Semiconductor is a 3A, 700V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V typical forward voltage at 3A/25°C, and 100A peak surge current - used for high-frequency freewheeling and output rectification in switching-mode power supplies.

For engineers reviewing the ES3CHR7G datasheet, ES3CHR7G pinout, ES3CHR7G application, or ES3CHR7G equivalent, key selection criteria include V_RRM = 700V, I_F = 3A, t_rr = 35ns, thermal resistance R_θJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly.

Technical Context

This super fast rectifier employs a glass-passivated silicon junction optimized for high-efficiency switching converters operating above 50kHz. Its low Q_rr and tight t_rr distribution support reduced switching losses and EMI in DC-DC stages and secondary-side rectification.

The device operates across -55°C to +150°C junction temperature range, with moisture sensitivity level 1 (J-STD-020), matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound - enabling robust reliability in industrial and telecom power designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	700 V - maximum repetitive reverse blocking voltage; defines safe operating margin in 400–600V DC bus applications
I_F	3 A continuous - average forward current rating at T_L = 75°C; determines heatsink-free operation in compact SMPS layouts
t_rr	35 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables >200kHz switching without excessive diode recovery loss
V_F	0.95 V typ @ 3A, 25°C - low conduction loss improves efficiency in high-current output rails
R_θJA	47 °C/W - junction-to-ambient thermal resistance; informs PCB copper area requirements for thermal management
I_FSM	100 A - non-repetitive surge rating for inrush and fault conditions; supports robust startup in offline converters

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-3EYH07-M3/45	V_RRM = 700V, t_rr = 30ns, V_F = 0.92V @ 3A - slightly faster but same package and thermal profile	Identical use in SMPS freewheeling; tighter t_rr spec may reduce EMI filtering cost	Preferred where <30ns t_rr is required for EMI compliance; same footprint and reflow profile
ON Semiconductor MUR370G	V_RRM = 700V, t_rr = 50ns, V_F = 1.15V @ 3A - slower recovery and higher conduction loss	Suitable for lower-frequency (<100kHz) converters where efficiency trade-off is acceptable	Select when cost sensitivity outweighs efficiency gain; requires thermal review due to higher V_F

Compared with VS-3EYH07-M3/45 and MUR370G, ES3CHR7G delivers balanced performance: 35ns t_rr ensures low switching loss without premium pricing, while its 0.95V V_F and DO-214AB thermal resistance support compact, thermally constrained designs without derating.

FAQ

What is the maximum junction temperature rating for ES3CHR7G?

The ES3CHR7G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows the ES3CHR7G to function reliably in industrial environments with elevated ambient temperatures, provided PCB thermal design maintains junction temperature within limits using its specified R_θJA = 47°C/W.

Is ES3CHR7G RoHS and halogen-free compliant?

Yes, ES3CHR7G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads and UL 94V-0 molding compound, meeting environmental and safety requirements for commercial and industrial electronics without requiring special handling or exemptions.

What does the 'R7G' suffix indicate in ES3CHR7G?

The 'R7G' suffix in ES3CHR7G denotes the 700V V_RRM rating (R7 = 700V) and green halogen-free compound (G). This follows Taiwan Semiconductor's ES3x family coding: ES3A = 50V, ES3B = 100V, ..., ES3J = 600V; ES3CHR7G extends the series to 700V with identical DO-214AB packaging and electrical behavior.

Can ES3CHR7G replace ES3J in existing designs?

ES3CHR7G is not a direct replacement for ES3J (600V) without validation. Although both share DO-214AB package and 3A rating, ES3CHR7G's 700V V_RRM offers higher blocking margin but may exhibit different V_F and t_rr curves. Review transient voltage stress and thermal performance before substituting ES3CHR7G for ES3J in legacy designs.

What is the reverse leakage current specification for ES3CHR7G at 100°C?

At T_J = 100°C and rated V_R, ES3CHR7G exhibits a maximum reverse leakage current (I_R) of 500 µA. This value is confirmed per the ES3x family electrical specifications and reflects stable junction integrity under elevated thermal stress - critical for maintaining efficiency in high-temperature power supply operation.
