Product details

Overview

ES3D R7G from Taiwan Semiconductor is a 200 V, 3 A super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, with 35 ns reverse recovery time, 0.95 V forward voltage at 3 A, and 100 A peak surge current - used for high-frequency freewheeling and SMPS output rectification in telecom power supplies.

For engineers reviewing the ES3D R7G datasheet, ES3D R7G pinout, ES3D R7G application, or ES3D R7G equivalent, key selection criteria include V_RRM = 200 V, I_F = 3 A, t_rr = 35 ns, V_F = 0.95 V @ 3 A, and DO-214AB thermal performance (R_θJL = 12 °C/W).

Technical Context

This single-die silicon rectifier features a glass-passivated junction and is optimized for switching-mode power conversion where low forward voltage and fast recovery minimize conduction and switching losses. Its 35 ns t_rr enables operation up to several hundred kHz without excessive switching loss or ringing.

The DO-214AB (SMC) package provides robust thermal dissipation (R_θJA = 47 °C/W, R_θJL = 12 °C/W) and supports automated placement per J-STD-020 Level 1 moisture sensitivity. Cathode polarity is marked by a band on the body.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage; sets safe operating margin for 170 V AC rectified inputs or 150 V DC bus clamping.
I_F	3 A continuous - average forward current rating at T_L = 75 °C; defines steady-state power delivery capability.
t_rr	35 ns - reverse recovery time at I_F = 0.5 A, I_R = 1.0 A; enables efficient operation in 200–500 kHz SMPS topologies.
V_F	0.95 V @ 3 A, 25 °C - forward voltage drop; directly determines conduction loss (P_cond ≈ 2.85 W at full load).
I_FSM	100 A - non-repetitive peak surge current (8.3 ms half-sine); withstands inrush and fault transients in offline converters.
C_J	45 pF @ 1 MHz, 4 V - junction capacitance; impacts high-frequency switching node ringing and EMI filter design.

Pinout & Package

DO-214AB (SMC) surface-mount package: molded epoxy case meeting UL 94V-0, matte tin-plated leads, cathode indicated by band, weight ≈ 0.210 g.

Equivalent & Alternatives

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EWH02-F	V_RRM = 200 V, I_F = 3 A, t_rr = 30 ns, V_F = 0.93 V @ 3 A, DO-214AB	Slightly faster t_rr and lower V_F, but higher cost and longer lead times in volume	Preferred when <5 ns t_rr reduction justifies premium pricing and supply chain trade-offs.
ON Semiconductor MUR320	V_RRM = 200 V, I_F = 3 A, t_rr = 35 ns, V_F = 0.97 V @ 3 A, DO-201AD (axial)	Same electrical specs but axial DO-201AD package - incompatible with SMT assembly and higher R_θJA	Only suitable for through-hole prototyping or legacy board rework; not drop-in for ES3D R7G's DO-214AB footprint.

Compared with VS-3EWH02-F and MUR320, ES3D R7G delivers identical t_rr and near-matched V_F in a fully SMT-compatible, moisture-level-1 DO-214AB package - making it optimal for high-volume telecom and industrial SMPS production where assembly yield and thermal reliability are critical.

FAQ

What is the maximum junction temperature rating for ES3D R7G?

The ES3D R7G has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows reliable operation in enclosed industrial power supplies without forced air cooling, provided PCB copper area and thermal vias meet recommended layout guidelines for DO-214AB packages. The ES3D R7G maintains rated performance up to this limit when derated per the forward current derating curve.

Is ES3D R7G RoHS and halogen-free compliant?

Yes, ES3D R7G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the Taiwan Semiconductor product specification document N2102. The molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. This compliance is certified for all production lots shipped under the R7G tape-and-reel packaging variant.

What does the 'R7G' suffix indicate in ES3D R7G?

The 'R7G' suffix in ES3D R7G denotes Taiwan Semiconductor's internal tape-and-reel packaging code: 'R' = reel, '7' = 3,000 pcs per reel, and 'G' = green compound (halogen-free). It does not affect electrical parameters - all ES3D variants share identical V_RRM = 200 V, t_rr = 35 ns, and V_F = 0.95 V characteristics regardless of suffix.

Can ES3D R7G replace ES3D in an existing design?

Yes, ES3D R7G is a direct replacement for ES3D - both share identical electrical specifications, DO-214AB package dimensions, pinout, and thermal performance. The 'R7G' suffix reflects updated halogen-free material and tape-and-reel packaging; no layout, firmware, or thermal redesign is required when migrating from legacy ES3D to ES3D R7G in production.

What is the reverse recovery charge (Q_rr) of ES3D R7G?

Taiwan Semiconductor does not publish Q_rr explicitly for ES3D R7G in the N2102 datasheet. However, based on the measured t_rr = 35 ns under I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A conditions, typical Q_rr is estimated at ≤ 12 nC. For precise Q_rr-dependent simulations (e.g., synchronous rectifier gate drive loss), engineers should validate using actual waveform measurements on the target board with the ES3D R7G installed.
