Product details

Overview

ES1C M2G from Taiwan Semiconductor is a 1 A, 150 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A, and 30 A peak surge current - deployed in DC-DC converter output stages for high-efficiency power conversion.

For engineers reviewing the ES1C M2G datasheet, ES1C M2G pinout, ES1C M2G application, or ES1C M2G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), thermal resistance (R_θJL = 35 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial and lighting power designs.

Technical Context

This single-die, glass-passivated silicon rectifier delivers super-fast switching performance optimized for high-frequency switching mode power supplies. Its 35 ns trr and low Q_rr minimize switching losses during freewheeling and snubber operation.

The device operates with a maximum junction temperature of 150 °C and exhibits stable reverse leakage (<5 µA at 25 °C, <100 µA at 125 °C), enabling reliable performance in thermally constrained PCB layouts with DO-214AC footprint constraints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	150 V - supports input/output isolation in 12–48 V DC-DC converters without derating
I_F	1 A continuous - suitable for medium-power secondary-side rectification
t_rr	35 ns - enables operation up to ~3 MHz switching frequency with low turn-off loss
V_F	0.95 V @ 1 A, 25 °C - reduces conduction loss vs. standard fast recovery diodes

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06U	V_RRM = 600 V, t_rr = 30 ns, V_F = 1.15 V @ 1 A - higher voltage rating, slightly higher V_F	Better suited for universal-input PFC front-ends where 600 V blocking is required	Select STTH1R06U only if system requires ≥400 V reverse standoff; ES1C M2G offers lower V_F and cost for 150 V designs.
MBR1150	Schottky structure, V_F = 0.82 V @ 1 A, V_RRM = 150 V, but I_R = 1 mA @ 125 °C - higher leakage, no trr spec	Preferred in ultra-low-loss, low-noise DC-DC outputs where reverse leakage is tolerable	Choose MBR1150 for lowest conduction loss; ES1C M2G provides superior high-temperature leakage control and robustness in snubber/freewheeling roles.

Compared with STTH1R06U and MBR1150, ES1C M2G delivers optimal balance of low forward drop, controlled reverse leakage, and proven ruggedness in 150 V-class switching power applications - especially where thermal stability and surge immunity are critical.

FAQ

What is the maximum junction temperature rating for ES1C M2G?

The ES1C M2G has a maximum junction temperature (T_J) rating of +150 °C, with operational capability down to –55 °C. This wide range supports deployment in enclosed industrial enclosures and automotive under-hood environments where ambient temperatures exceed 100 °C. Derating curves confirm 1 A continuous current is maintainable up to 115 °C case temperature when mounted on 1-inch² 2-oz copper.

Does ES1C M2G have a specified reverse recovery time (t_rr)?

Yes, ES1C M2G specifies a typical reverse recovery time (t_rr) of 35 ns under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is measured per JEDEC standards and confirmed across production lots, making ES1C M2G suitable for switching frequencies up to 1–2 MHz in resonant and hard-switched topologies.

Is ES1C M2G RoHS and halogen-free compliant?

Yes, ES1C M2G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated per J-STD-002. These certifications are verified in TSC's official product change notices and material declarations dated O2112 revision.

What is the forward voltage (V_F) of ES1C M2G at rated current?

The forward voltage of ES1C M2G is guaranteed ≤0.95 V at I_F = 1 A and T_J = 25 °C, with typical values near 0.87 V. At elevated junction temperatures (125 °C), V_F decreases slightly due to negative temperature coefficient - a characteristic confirmed in TSC's Fig.4 Typical Forward Characteristics curve.

What package type does ES1C M2G use, and is it compatible with standard SMA footprints?

ES1C M2G uses the DO-214AC (SMA) package, with standardized dimensions and lead spacing matching IPC-7351B SMA footprint guidelines. Its cathode band marking, 0.060 g weight, and matte tin plating ensure compatibility with automated pick-and-place and lead-free reflow profiles - fully validated per J-STD-020 MSL Level 1.
