Product details

Overview

ES3C R7G from Taiwan Semiconductor is a 3A, 150V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 3A/25°C, and 100A peak surge current - used in high-frequency switching mode power supplies for telecom and computing.

For engineers reviewing the ES3C R7G datasheet, ES3C R7G pinout, ES3C R7G application, or ES3C R7G equivalent, key selection criteria include V_RRM = 150 V, I_F = 3 A, t_rr = 35 ns, R_θJA = 47 °C/W, and DO-214AB mechanical compatibility with automated SMT assembly.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve stable thermal performance and moisture resistance (J-STD-020 Level 1). Its super-fast recovery enables efficient operation in 100–500 kHz SMPS topologies where low switching loss and minimal reverse recovery charge are critical.

The device operates across –55°C to +150°C junction temperature range, with 12°C/W junction-to-lead thermal resistance supporting high-current conduction without derating in thermally constrained layouts. Cathode band marking ensures unambiguous polarity identification during placement and inspection.

I_F	3 A continuous - supports sustained 3 A forward conduction at T_A = 25°C without forced cooling
t_rr	35 ns - enables high-frequency switching (>200 kHz) with low recovery loss and reduced EMI generation
V_F @ 3 A	≤ 0.95 V - minimizes conduction loss (≤2.85 W at full load), reducing heatsink requirements
R_θJA	47 °C/W - defines thermal rise above ambient per watt dissipated; usable on standard 1-oz copper PCBs
I_FSM	100 A - withstands short-duration inrush or fault currents typical in AC input rectification stages
Junction temp	–55°C to +150°C - supports industrial and telecom environments with wide ambient operating range

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-3EYH01-M3/54	V_RRM = 100 V, t_rr = 25 ns, V_F = 0.89 V @ 3 A - lower V_RRM, faster recovery	Better suited for ≤100 V output rails; less margin for line transients in 48 V systems	Select when prioritizing lowest t_rr and V_F over voltage headroom
ON Semiconductor MUR3150CT	Dual common-cathode configuration, V_RRM = 150 V, t_rr = 50 ns - higher recovery time, dual-diode package	Requires different layout; intended for dual-output or complementary rectification	Choose only if dual-diode topology is required; not a drop-in replacement

Compared with VS-3EYH01-M3/54 and MUR3150CT, ES3C R7G offers optimal balance of 150 V rating, 35 ns recovery, and single-diode DO-214AB packaging - making it preferred for cost-sensitive, space-constrained 48 V telecom and server power designs requiring proven manufacturability and thermal robustness.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for ES3C R7G?

The ES3C R7G has a V_RRM of 150 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version N2102). This rating defines the highest reverse voltage the device can block repeatedly without breakdown, making it suitable for 48 V output systems with transient margin. The ES3C R7G must not be operated beyond this limit under any condition.

Does ES3C R7G have a specified reverse recovery time (t_rr)?

Yes, ES3C R7G has a maximum reverse recovery time of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions per the Electrical Specifications table. This value is consistent across the ES3A–ES3D subgroup and is critical for minimizing switching loss in high-frequency SMPS designs using the ES3C R7G.

What package type does ES3C R7G use, and is it RoHS compliant?

ES3C R7G uses the DO-214AB (SMC) surface-mount package with matte tin-plated leads and UL 94V-0 molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the Features section of the Taiwan Semiconductor datasheet. The ES3C R7G meets J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.

What is the forward voltage (V_F) of ES3C R7G at rated current?

At I_F = 3 A and T_J = 25°C, ES3C R7G has a maximum forward voltage of 0.95 V, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss - for example, resulting in ≤2.85 W dissipation at full rated current in the ES3C R7G.

Is ES3C R7G suitable for high-temperature industrial environments?

Yes, ES3C R7G supports junction temperatures from –55°C to +150°C and has a thermal resistance R_θJA of 47 °C/W. Its glass-passivated junction and DO-214AB package enable reliable operation in sealed industrial enclosures up to 60°C ambient, provided PCB copper area and airflow meet minimum layout guidelines defined for the ES3C R7G.
