Taiwan Semiconductor Corporation ES3A M6G

Overview

ES3A M6G from Taiwan Semiconductor is a 3 A, 50 V super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 35 ns reverse recovery time, 0.95 V max forward voltage at 3 A, and 100 A peak surge current - used for high-frequency freewheeling and output rectification in SMPS for telecom and computing.

For engineers reviewing the ES3A M6G datasheet, ES3A M6G pinout, ES3A M6G application, or ES3A M6G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (R_θJL = 12 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power supply design.

Technical Context

This single-die, glass-passivated silicon rectifier delivers super-fast switching performance with trr ≤ 35 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. Its low VF (≤ 0.95 V @ 3 A, 25 °C) and low CJ (45 pF @ 1 MHz, 4 V) support high-efficiency operation in 100 kHz–1 MHz switching converters.

The DO-214AB (SMC) package provides robust thermal dissipation (R_θJA = 47 °C/W) and meets J-STD-020 moisture sensitivity level 1, enabling compatibility with standard reflow profiles. Polarity is marked by cathode band; terminals are matte tin-plated and whisker-tested per JESD 201 Class 2.

FAQ

What is the maximum junction temperature rating for ES3A M6G?

The ES3A M6G has a maximum junction temperature (T_J) rating of +150 °C and a minimum of –55 °C. This wide operating range allows reliable use in industrial environments where ambient temperatures exceed 85 °C. The device's thermal resistance values (R_θJL = 12 °C/W, R_θJA = 47 °C/W) enable accurate junction temperature estimation under real-world PCB layout conditions. Always verify thermal design using actual power dissipation and copper area in the final ES3A M6G implementation.

Is ES3A M6G RoHS and halogen-free compliant?

Yes, ES3A M6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability standards, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are verified in Taiwan Semiconductor's official documentation (Version N2102) and confirmed on authorized distributor listings. ES3A M6G is suitable for export to EU, Japan, and other regulated markets requiring strict environmental compliance.

What does the "M6G" suffix indicate in ES3A M6G?

The "M6G" suffix in ES3A M6G denotes Taiwan Semiconductor's internal packaging and marking code: "M" indicates tape-and-reel packaging (3,000 pcs/reel), "6" specifies green compound (halogen-free), and "G" identifies the date code format per TSC's standard marking convention. It does not alter electrical specifications - all ES3A devices share identical VRRM = 50 V, IF = 3 A, trr ≤ 35 ns, and VF ≤ 0.95 V characteristics regardless of suffix variant. ES3A M6G is functionally identical to ES3A in DO-214AB (SMC) package.

Can ES3A M6G replace a standard FR304 in a 50 V application?

ES3A M6G can replace FR304 in 50 V applications only if the design requires super-fast recovery (trr ≤ 35 ns vs. FR304's ~500 ns). While both share VRRM = 50 V and IF = 3 A, ES3A M6G's significantly faster recovery reduces switching losses and EMI in high-frequency SMPS. However, its VF is slightly higher than some ultra-fast alternatives. Verify layout compatibility: ES3A M6G uses DO-214AB (SMC), whereas FR304 uses DO-201AD - different footprints require PCB redesign. ES3A M6G is not a drop-in mechanical replacement.

What is the reverse leakage current specification for ES3A M6G at 100 °C?

At junction temperature T_J = 100 °C and rated reverse voltage (V_R = 50 V), the maximum reverse leakage current (I_R) for ES3A M6G is 500 µA, per Taiwan Semiconductor's Electrical Specifications table (N2102). At 25 °C, I_R is limited to 10 µA. This elevated leakage at high temperature is typical for silicon rectifiers and must be accounted for in low-power standby circuits or precision bias networks. Thermal derating curves in the ES3A M6G datasheet confirm this behavior across the full –55 to +150 °C range.
