Product details
Overview
ES1CHR3G from Taiwan Semiconductor is a 1 A, 50 V super fast surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A and 25°C, and 30 A peak surge current capability. It serves as a freewheeling or snubber diode in compact DC-DC converters.
For engineers reviewing the ES1CHR3G datasheet, ES1CHR3G pinout, ES1CHR3G application, or ES1CHR3G equivalent, key selection criteria include reverse recovery speed, thermal resistance (RθJL = 35°C/W), junction temperature rating (–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 super-fast switching performance with low stored charge. Its DO-214AC (SMA) package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
The device operates across –55°C to +150°C junction temperature range, with 85°C/W junction-to-ambient thermal resistance and 35°C/W junction-to-lead thermal resistance-enabling reliable conduction in space-constrained, thermally demanding switch-mode power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 1 A - continuous forward current rating at TA = 75°C, defining maximum steady-state power handling |
| VRRM | 50 V - peak repetitive reverse voltage, sets maximum blocking capability in flyback or clamp circuits |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency operation up to ~3 MHz |
| VF @ 1 A, 25°C | 0.95 V - forward voltage drop directly impacts conduction loss and thermal design in 12 V/24 V DC-DC stages |
| RθJL | 35 °C/W - junction-to-lead thermal resistance determines heatsinking requirements when mounted on PCB copper |
| IR @ 50 V, 25°C | 5 µA - low leakage ensures minimal standby power loss in energy-sensitive applications |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 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 |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to higher-potential rail (e.g., output capacitor positive) in freewheeling path |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures long-term reliability under thermal cycling and humidity exposure without hermetic sealing |
| Super fast recovery (35 ns) | Reduces switching losses and EMI generation compared to standard rectifiers in >100 kHz SMPS |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow, supporting direct SMT assembly without preconditioning |
| Halogen-free & RoHS compliant | Fulfills IEC 61249-2-21 and EU RoHS directives for environmentally regulated industrial end equipment |

IC Role / Device Role / Timing Role: Input bridge rectifier or auxiliary supply rectifier in multi-rail isolated converters. Use Value: –55°C to +150°C TJ range and J-STD-020 Level 1 rating ensure uninterrupted operation across extended industrial temperature profiles. |
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 MUR150 | Same DO-214AC package, 1 A/50 V, but trr = 50 ns (vs. 35 ns); VF = 1.0 V typical | Slightly higher switching loss in >300 kHz designs; suitable where margin exists | Select ES1CHR3G when minimizing reverse recovery loss is critical in high-frequency DC-DC stages |
| Vishay VS-1EH01-M3/5AT | DO-214AC, 1 A/50 V, trr = 35 ns identical, but IR = 10 µA max at 25°C (vs. 5 µA) | Higher leakage may affect ultra-low-power standby modes in battery-backed systems | Prefer ES1CHR3G for applications requiring lowest possible reverse leakage below 10 µA |
Compared with MUR150 and VS-1EH01-M3/5AT, ES1CHR3G delivers the lowest combination of trr (35 ns) and IR (5 µA) in the 1 A/50 V super fast rectifier class, making it optimal for high-efficiency, high-frequency industrial power conversion where both switching and leakage losses must be minimized.

FAQ
What is the maximum junction temperature rating for ES1CHR3G?
The ES1CHR3G has a maximum junction temperature (TJ) rating of +150°C and a minimum of –55°C. This wide operating range allows deployment in industrial environments with elevated ambient temperatures, such as enclosed power supplies or motor drive enclosures. The device's RθJL of 35°C/W supports effective heat transfer to the PCB, ensuring ES1CHR3G remains within safe thermal limits under sustained 1 A load conditions.
Does ES1CHR3G meet RoHS and halogen-free requirements?
Yes, ES1CHR3G is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor certifies the molding compound and plating materials used in ES1CHR3G to satisfy both environmental standards. This makes ES1CHR3G suitable for export to EU, Japan, and other regulated markets, and aligns with sustainability goals in industrial and medical-grade power supply designs.
What is the reverse recovery time (trr) specification for ES1CHR3G?
The reverse recovery time (trr) for ES1CHR3G is specified at 35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet for the ES1A–ES1J family. The 35 ns trr enables efficient operation in switching power supplies running above 200 kHz, reducing switching losses and associated EMI compared to standard recovery diodes.
Is ES1CHR3G suitable for use in automotive applications?
No, ES1CHR3G is not qualified for automotive applications. Taiwan Semiconductor explicitly states that the ES1A–ES1J series is "not designed for use in medical, life-saving, or life-sustaining applications," and does not carry AEC-Q101 qualification. While its –55°C to +150°C junction temperature range overlaps with some automotive ambient requirements, ES1CHR3G lacks the required stress testing, failure analysis, and traceability documentation for automotive-grade deployment.
What packaging and reel quantity is available for ES1CHR3G?
ES1CHR3G is supplied in DO-214AC (SMA) package on 7,500-piece tape-and-reel format, conforming to industry-standard EIA-481 specifications. The reel packaging supports high-speed pick-and-place assembly and complies with J-STD-020 moisture sensitivity level 1, eliminating the need for pre-baking before reflow soldering-a key advantage for high-throughput manufacturing lines using ES1CHR3G.
