Product details

Overview

ES3D V7G from Taiwan Semiconductor is a 200V, 3A 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 ES3D V7G datasheet, ES3D V7G pinout, ES3D V7G application, or ES3D V7G equivalent, key selection criteria include repetitive peak reverse voltage (200V), thermal resistance (R_θJL = 12°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial-grade power conversion designs.

Technical Context

This single-die, glass-passivated super fast rectifier delivers low conduction loss and minimal switching loss due to its 35ns trr and sub-1V VF, enabling efficient operation in 100–500kHz SMPS topologies. Its DO-214AB package supports automated placement and meets J-STD-020 moisture sensitivity level 1.

The device operates across –55°C to +150°C junction temperature, with R_θJA = 47°C/W and R_θJL = 12°C/W, allowing direct lead-to-heatsink thermal path optimization. Polarity is marked by cathode band; terminals are matte tin-plated per J-STD-002.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum non-repetitive reverse blocking voltage; defines safe operating margin in 12–48V output DC-DC converters.
I_F	3 A continuous - rated average forward current at T_L = 75°C; supports sustained load in compact SMC footprint.
t_rr	35 ns - measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables high-frequency operation with low switching loss.
V_F (max)	0.95 V at I_F = 3A, T_J = 25°C - low conduction drop improves efficiency in low-voltage secondary-side rectification.
R_θJL	12 °C/W - junction-to-lead thermal resistance; allows direct PCB copper pour heatsinking without external heatsink.
I_FSM	100 A - 8.3ms half-sine surge rating; withstands inrush and transient overloads in offline SMPS inputs.

FAQ

What is the maximum junction temperature rating for ES3D V7G?

The ES3D V7G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range ensures reliable performance in industrial environments where ambient temperatures exceed 85°C. The device's R_θJL of 12°C/W allows effective heat transfer to the PCB copper, making ES3D V7G suitable for thermally constrained layouts without additional heatsinking.

Does ES3D V7G meet RoHS and halogen-free requirements?

Yes, ES3D V7G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating per J-STD-002. These attributes make ES3D V7G acceptable for environmentally regulated markets including EU, Japan, and China RoHS zones.

What is the reverse recovery time specification for ES3D V7G?

The reverse recovery time (t_rr) for ES3D V7G is 35 ns, tested under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed across the full temperature range and directly supports high-frequency operation up to 500 kHz in SMPS designs. The consistent t_rr ensures predictable switching behavior in synchronous rectifier control schemes.

Is ES3D V7G suitable for freewheeling applications?

Yes, ES3D V7G is explicitly qualified for freewheeling applications, as stated in its official applications list. Its 35 ns t_rr and low Q_rr minimize voltage spikes and EMI during inductive turn-off events. In buck or forward converters, ES3D V7G clamps stored energy efficiently while maintaining low conduction loss - a key requirement for stable freewheeling operation.

What packaging and reel quantity does ES3D V7G ship in?

ES3D V7G is supplied in DO-214AB (SMC) package on 3,000-piece tape-and-reel format per industry standard. The reel complies with EIA-481-D specifications and includes moisture barrier bag packaging per J-STD-020 Level 1 requirements - eliminating pre-bake steps before SMT assembly and supporting high-yield automated placement.
