Product details

Overview

ES1J R3G from Taiwan Semiconductor is a 1 A, 600 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 1.70 V max forward voltage at 1 A and 25°C, and 5 µA max reverse leakage at rated VR and 25°C, used for snubber and freewheeling functions in high-frequency switching power supplies.

For engineers reviewing the ES1J R3G datasheet, ES1J R3G pinout, ES1J R3G application, or ES1J R3G equivalent, key selection criteria include peak repetitive reverse voltage (600 V), ultra-fast trr (≤35 ns), thermal resistance (R_θJL = 35°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

This single-die silicon rectifier uses glass-passivated junction technology to achieve stable performance under rapid voltage transients and high di/dt conditions. Its 35 ns reverse recovery time enables efficient operation in DC–DC converters and switching inverters operating above 100 kHz.

The device is rated for 30 A non-repetitive surge current (8.3 ms half-sine), supports automated SMT placement per J-STD-020 Level 1 moisture sensitivity, and maintains ≤5 µA IR at 25°C and ≤100 µA at 125°C - critical for low-loss standby and hold-up circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - blocks up to 600 V repetitive reverse voltage without breakdown, suitable for 400 V DC bus applications with safety margin
I_F	1 A continuous - delivers rated forward current with T_J ≤ 150°C under standard heatsinking (R_θJA = 85°C/W)
t_rr	35 ns max - minimizes switching losses and EMI in high-frequency SMPS topologies (e.g., active clamp flyback)
V_F	1.70 V max @ 1 A, 25°C - defines conduction loss budget; increases with temperature but remains <2.1 V at 125°C
I_R	5 µA max @ 600 V, 25°C - ensures low leakage in high-impedance snubber networks and voltage-clamp circuits
R_θJL	35°C/W - enables direct PCB copper pour thermal path to improve power handling beyond ambient-limited R_θJA = 85°C/W

Pinout & Package

DO-214AC (SMA) surface-mount package with cathode-indicating band; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node (e.g., switch node in buck converter); polarity must match PCB silkscreen marking
Cathode	Forward current exit / reverse blocking terminal	Marked by band; ties to higher-potential rail (e.g., output capacitor positive) and absorbs reverse recovery energy

Key Features

Feature	Design Value
Glass-passivated junction	Ensures long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments
Super fast recovery (t_rr ≤ 35 ns)	Reduces turn-off switching loss by >40% vs. standard rectifiers (e.g., 1N4007), enabling higher frequency operation
Moisture sensitivity Level 1	Allows unlimited floor life before reflow; no baking required prior to SMT assembly
RoHS & halogen-free	Meets IEC 61249-2-21 and EU Directive 2011/65/EU; compatible with lead-free reflow profiles and green manufacturing

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	V_F = 1.7 V max (same), t_rr = 30 ns (5 ns faster), R_θJL = 30°C/W (5°C/W lower)	Better thermal performance suits higher ambient or constrained layouts; identical DO-214AC footprint	Select when board-level thermal resistance is >40°C/W and junction temperature margin is critical
ON Semi MUR160	V_RRM = 600 V (same), t_rr = 50 ns (15 ns slower), V_F = 1.75 V max (slightly higher)	Higher Q_rr increases switching loss in >200 kHz designs; same package and polarity marking	Acceptable for cost-sensitive 50–100 kHz applications where 35 ns t_rr is not mandatory

Compared with STTH1R06 and MUR160, ES1J R3G offers balanced trade-offs: identical V_RRM and V_F, mid-range t_rr (35 ns), and industry-standard thermal resistance - making it optimal for general-purpose high-frequency industrial power supplies where layout flexibility and supply chain stability are prioritized.
