Product details
Overview
ES1JF R2G from Taiwan Semiconductor is a 1A, 600V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 1.70V max forward voltage at 1A/25°C, and 5µA max reverse leakage at 25°C, used in snubber circuits and DC-DC converters requiring high efficiency and compact layout.
For engineers reviewing the ES1JF R2G datasheet, ES1JF R2G pinout, ES1JF R2G application, or ES1JF R2G equivalent, key selection considerations include its 600V VRRM, 30A IFSM, 150°C junction temperature rating, moisture sensitivity level 1 compliance, and RoHS/halogen-free status for industrial power conversion designs.
Technical Context
This single-die, unidirectional silicon rectifier uses glass-passivated junction technology to achieve stable thermal performance and reliable operation under repetitive surge conditions. Its 35ns trr enables high-frequency switching in SMPS and inverters without excessive switching loss.
The device operates across -55°C to +150°C junction temperature range with RθJL = 35°C/W and RθJA = 85°C/W, supporting high-power-density board layouts where lead-to-ambient thermal path must be managed without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating limit in 400–600V DC bus applications |
| IF | 1 A continuous - Rated average forward current at 75°C case temperature; supports sustained conduction in compact converters |
| trr | 35 ns - Measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables >1 MHz switching in resonant topologies |
| VF (max) | 1.70 V @ 1A, 25°C - Forward drop directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| IR (max) | 5 µA @ 25°C - Low leakage preserves efficiency in high-impedance bias networks and standby modes |
| RθJA | 85 °C/W - Thermal resistance from junction to ambient; determines required PCB copper area for natural convection cooling |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration with cathode band marking. Matte tin-plated leads, UL 94V-0 molding compound, 0.060g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; polarity must match input source or inductive flyback node |
| Cathode | Forward current exit point | Marked by band; connects to higher-potential rail or output capacitor positive terminal in freewheeling paths |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in IPC Class 2 environments |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) and associated switching losses in 100–500 kHz SMPS designs |
| Moisture sensitivity level 1 | Allows unlimited floor life before reflow; no baking required prior to automated SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES1JHM3/5A | Same DO-214AC package, identical 600V VRRM and 1A IF, but 50ns trr (vs. 35ns for ES1JF R2G) | Slightly higher switching loss in >300 kHz designs; otherwise interchangeable in 60–200 kHz lighting and converter use | Select ES1JF R2G when minimizing reverse recovery loss is critical; choose VS-ES1JHM3/5A if legacy qualification or dual-sourcing is required |
| ON Semiconductor MUR160RLG | DO-41 through-hole package, 600V VRRM, 1A IF, 60ns trr, higher VF (1.75V) | Not surface-mount compatible; requires PCB redesign; suited for prototyping or low-volume through-hole assemblies | Use only if DO-214AC footprint is unavailable; ES1JF R2G offers superior thermal performance and automated assembly compatibility |
Compared with VS-ES1JHM3/5A and MUR160RLG, ES1JF R2G delivers the fastest recovery (35ns), lowest thermal resistance (RθJA = 85°C/W), and full SMT readiness-making it optimal for space-constrained, high-efficiency industrial power supplies where layout density and switching loss matter.

FAQ
What is the maximum junction temperature rating for ES1JF R2G?
The ES1JF R2G has a maximum junction temperature (TJ) of +150°C, with an operational range from -55°C to +150°C. This rating allows reliable operation in enclosed industrial enclosures or near heat-generating components. The device's RθJL of 35°C/W supports efficient heat transfer to the PCB pad, and its 85°C/W RθJA value helps designers estimate required copper area for passive cooling without heatsinks. Always verify actual TJ using measured case temperature and power dissipation in the final layout.
Does ES1JF R2G meet RoHS and halogen-free requirements?
Yes, ES1JF R2G is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and the matte tin-plated leads satisfy J-STD-002 solderability standards. These certifications make ES1JF R2G suitable for export-controlled and environmentally regulated applications including industrial automation and outdoor LED lighting. Documentation is available upon request from Taiwan Semiconductor's official product page.
What is the reverse recovery time (trr) specification for ES1JF R2G?
The ES1JF R2G has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet (Version O2112) and reflects true super-fast switching behavior. The low trr reduces switching losses and voltage spikes in high-frequency DC-DC converters, making ES1JF R2G especially effective in 200–500 kHz flyback and forward topologies.
Is ES1JF R2G suitable for snubber circuit applications?
Yes, ES1JF R2G is explicitly recommended for snubber circuits per Taiwan Semiconductor's application guidance. Its 600V VRRM, 35ns trr, and low Qrr enable rapid clamping of voltage transients across switching devices. In RCD snubbers, ES1JF R2G minimizes energy loss during turn-off and avoids oscillatory ringing. Its DO-214AC package supports high-density placement adjacent to MOSFETs or IGBTs, and its 30A IFSM handles transient surge currents reliably.
What packaging and moisture sensitivity level does ES1JF R2G have?
ES1JF R2G is supplied in DO-214AC (SMA) package on 7,500-piece tape-and-reel format and carries moisture sensitivity level (MSL) 1 per J-STD-020. This means it has unlimited floor life at ≤30°C/60% RH and requires no pre-bake before reflow soldering. The matte tin-plated leads ensure robust solder joint formation, and the UL 94V-0 molding compound provides flame resistance. These attributes make ES1JF R2G ideal for high-throughput SMT lines without special handling protocols.
