Product details

Overview

ES2BA M2G from Taiwan Semiconductor is a 2A, 100V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 2A/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency switching power supplies.

For engineers reviewing the ES2BA M2G datasheet, ES2BA M2G pinout, ES2BA M2G application, or ES2BA M2G equivalent, key selection criteria include V_RRM = 100 V, I_F = 2 A, t_rr = 35 ns, V_F = 0.95 V, and DO-214AC thermal performance (R_θJA = 75 °C/W).

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve stable super-fast recovery (t_rr ≤ 35 ns) with low forward voltage drop. Its DO-214AC package supports automated placement and meets J-STD-020 moisture sensitivity level 1.

Designed for high-efficiency DC-DC conversion, it operates across -55°C to +150°C junction temperature range, with R_θJL = 20 °C/W enabling effective heat transfer to PCB copper. Reverse leakage remains ≤10 µA at 25°C and ≤350 µA at 125°C under rated V_R.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR2100E	V_RRM = 100 V, t_rr = 35 ns, V_F = 0.95 V, same DO-214AC package	Identical electrical specs; differs in JEDEC-compliant marking and traceability documentation	Preferred where automotive PPAP documentation or AEC-Q101 qualification is required
Vishay VS-ES2BA-M3/5BT	V_RRM = 100 V, t_rr = 35 ns, V_F = 0.95 V, same DO-214AC package	Same core parameters; differs in halogen-free compliance certification scope and tape/reel packaging standard	Selected when UL 94V-0 verification per specific batch lot testing is mandated

Compared with MUR2100E and VS-ES2BA-M3/5BT, ES2BA M2G offers identical electrical performance and mechanical form factor but is distinguished by Taiwan Semiconductor's M2G marking code, J-STD-020 Level 1 handling, and IEC 61249-2-21 halogen-free validation-making it optimal for cost-sensitive industrial and lighting BOMs requiring full compliance traceability.

FAQ

What is the maximum junction temperature rating for ES2BA M2G?

The ES2BA M2G has a maximum junction temperature (T_J) of +150°C and a minimum of -55°C. This wide operating range allows deployment in thermally demanding environments such as enclosed LED drivers or industrial power supplies without forced air cooling. The ES2BA M2G maintains stable electrical characteristics-including V_F and t_rr-across this full range, as verified in TSC's thermal characterization curves.

Does ES2BA M2G meet RoHS and halogen-free requirements?

Yes, ES2BA M2G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses bromine- and chlorine-free molding compound and lead-free matte tin plating on terminals. These compliance attributes are confirmed in TSC's official product change notices and material declarations, and are fully traceable through Aetrix Electronics' certified supply chain for ES2BA M2G.

What is the reverse recovery time (t_rr) specification for ES2BA M2G?

The ES2BA M2G has a maximum reverse recovery time (t_rr) of 35 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is guaranteed across the full operating temperature range and is critical for minimizing switching losses in high-frequency power converters. The ES2BA M2G achieves this performance via optimized silicon doping and glass passivation, as documented in TSC's Electrical Specifications table.

Is ES2BA M2G suitable for use in snubber circuits?

Yes, ES2BA M2G is explicitly recommended for snubber applications per TSC's Applications section. Its 100 V V_RRM, 50 A I_FSM, and 35 ns t_rr enable effective clamping of voltage transients during IGBT or MOSFET turn-off. The DO-214AC package provides low-inductance mounting, and the device's low C_J (25 pF) avoids unintended resonance in RC snubber networks-key advantages confirmed in ES2BA M2G's Characteristics Curves.

What does the "M2G" suffix indicate in ES2BA M2G?

The "M2G" suffix in ES2BA M2G denotes Taiwan Semiconductor's internal manufacturing and compliance code: "M2" refers to the M2102 revision version of the ES2xx family datasheet, and "G" indicates green (halogen-free) compound per IEC 61249-2-21. This marking is laser-etched on the DO-214AC body and aligns with TSC's standardized coding for environmental compliance-distinct from other variants like M2E or M2F that may differ in plating or moisture sensitivity level.
