Product details
Overview
ES3HB R5G from Taiwan Semiconductor is a 3A, 600V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.11–1.30V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 34pF junction capacitance - deployed in high-frequency SMPS secondary-side rectification.
For engineers reviewing the ES3HB R5G datasheet, ES3HB R5G pinout, ES3HB R5G application, or ES3HB R5G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 24°C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SMB footprint compatibility with automated placement.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction optimized for high-efficiency switching applications. Its 600V VRRM, 100A IFSM, and 35ns trr enable operation in 100–500kHz DC-DC converters where low conduction loss and minimal reverse recovery charge are critical.
The device operates across –55°C to +150°C junction temperature range and delivers stable performance under pulsed forward current (3A) and high-temperature reverse bias (100µA IR at 125°C). Thermal design leverages low RθJL (24°C/W) for PCB-mounted heat dissipation on 10mm × 10mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400VAC mains-derived SMPS and industrial 3-phase bridge outputs |
| IF | 3 A continuous - sustains full-load output in 36–75W adapter and lighting driver designs |
| trr | 35 ns - minimizes switching losses and EMI in high-frequency flyback and LLC resonant converters |
| VF @ 1.5A, 25°C | 1.11–1.30 V - defines conduction loss budget (≈1.7–2.0W at 1.5A) for thermal management |
| CJ @ 1MHz, 4V | 34 pF - limits capacitive coupling noise and improves high-frequency transient response |
| RθJL | 24 °C/W - enables direct thermal path to PCB copper, reducing need for heatsinking in space-constrained layouts |
| MSL Level | Level 1 per J-STD-020 - allows unlimited floor life and standard reflow without baking preconditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES3E60-M3/5BT | Same DO-214AA package; 3A/600V; VF = 1.25V @ 3A/25°C; trr = 35ns; RθJA = 80°C/W | Slightly higher VF increases conduction loss by ~0.15W at full load vs. ES3HB R5G | Preferred where Vishay qualification or alternate sourcing is required; identical thermal pad layout |
| ON Semiconductor MUR360RLG | DO-214AA; 3A/600V; VF = 1.35V @ 3A/25°C; trr = 50ns; RθJA = 85°C/W | Slower recovery adds ~15ns delay, increasing switching loss in >200kHz designs | Acceptable for lower-frequency SMPS (<150kHz); verify EMI with added trr-induced overshoot |
Compared with VS-ES3E60-M3/5BT and MUR360RLG, ES3HB R5G offers the lowest forward voltage in its 600V class at elevated temperatures (0.99V @ 3A/125°C), enabling tighter thermal margins in compact, sealed power supplies.

FAQ
What is the maximum junction temperature rating for ES3HB R5G?
The ES3HB R5G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows operation in sealed industrial enclosures and high-ambient LED driver environments without forced cooling. Derating begins above 25°C ambient per the forward current derating curve, and thermal design must account for RθJL = 24°C/W to maintain safe junction temperatures under full 3A load.
Is ES3HB R5G compatible with lead-free reflow profiles?
Yes, ES3HB R5G is fully compatible with standard IPC/JEDEC J-STD-020 lead-free reflow profiles. Its MSL Level 1 classification confirms unlimited floor life and no bake requirement prior to assembly. Matte tin-plated leads meet J-STD-002 solderability standards, and the DO-214AA package withstands peak reflow temperatures up to 260°C for 30 seconds - matching typical Pb-free SAC305 process windows.
What does the 'R5G' suffix indicate in ES3HB R5G?
The 'R5G' suffix in ES3HB R5G denotes Taiwan Semiconductor's tape-and-reel packaging variant: R5 indicates 3,000 units per reel, and G signifies green (halogen-free) molding compound per IEC 61249-2-21. This matches the ordering code structure defined in the official datasheet, where ES3xB denotes the voltage family (B = 600V), and R5G specifies packaging and environmental compliance - not electrical differentiation.
How does ES3HB R5G compare to ES3GB in terms of forward voltage?
At 3.0A and 25°C, ES3HB R5G exhibits a forward voltage (VF) of 1.24–1.45V, while ES3GB is rated at 0.98–1.13V under identical conditions. This 0.26V higher VF reflects the higher 600V blocking capability of ES3HB R5G versus ES3GB's 400V rating. The trade-off enables use in universal-input front-end rectifiers where peak line voltage exceeds 400VDC, with corresponding increase in conduction loss.
Can ES3HB R5G be used as a direct replacement for MUR360 in existing designs?
ES3HB R5G is not a drop-in replacement for MUR360 due to differences in reverse recovery time (35ns vs. 50ns) and forward voltage profile. While both share DO-214AA packaging and 600V rating, the faster trr of ES3HB R5G may alter snubber requirements and EMI behavior. Layout changes are not needed, but system-level validation - especially of voltage overshoot and thermal rise - is required before substitution in production designs.
