Product details
Overview
ES3HB M4G from Taiwan Semiconductor is a 3A, 600V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 1.11V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 34pF junction capacitance - deployed in high-frequency SMPS output stages.
For engineers reviewing the ES3HB M4G datasheet, ES3HB M4G pinout, ES3HB M4G application, or ES3HB M4G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 24°C/W), forward voltage temperature coefficient, and moisture sensitivity level (MSL 1).
Technical Context
This single-die silicon rectifier uses glass-passivated PN junction technology to achieve super-fast switching with low stored charge. Its 600V VRRM and 100A IFSM support robust surge handling in offline power converters.
The device operates across –55°C to +150°C junction temperature range and exhibits stable forward voltage behavior up to 125°C (0.99V at 3.0A), enabling reliable performance in thermally constrained PCB layouts with 10mm × 10mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage without breakdown |
| IF | 3 A - Continuous average forward current at TA = 75°C on standard PCB |
| trr | 35 ns - Reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A |
| VF @ 1.5A, 25°C | 1.11 V - Forward voltage drop defining conduction loss at light-to-moderate load |
| CJ | 34 pF - Junction capacitance at 1MHz, 4V reverse bias; impacts high-frequency switching noise |
| RθJL | 24 °C/W - Thermal resistance from junction to lead; enables direct thermal path to PCB copper |

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-3EYH06-M3/54 | Same 600V VRRM, 3A IF, but 50ns trr and higher VF (1.3V @ 3A) | Suitable where slightly slower recovery is acceptable and cost sensitivity dominates | Prefer ES3HB M4G when minimizing switching loss and EMI is critical |
| ON Semiconductor MUR360G | 600V VRRM, 3A IF, but TO-220AC package (not surface-mount); trr = 50ns | Requires through-hole assembly and larger board area; better heat sinking capability | Select ES3HB M4G for SMT-only production and space-constrained designs |
Compared with VS-3EYH06-M3/54 and MUR360G, ES3HB M4G delivers superior high-frequency efficiency via its 35ns recovery and optimized VF/CJ trade-off - making it preferred for compact, high-switching-frequency SMPS where thermal and EMI margins are tight.

FAQ
What is the maximum junction temperature rating for ES3HB M4G?
The ES3HB M4G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. Derating curves confirm usable current capacity down to 75°C ambient at full 3A load. The ES3HB M4G must be mounted on a PCB with adequate copper area to maintain thermal compliance.
Does ES3HB M4G support lead-free reflow soldering?
Yes, ES3HB M4G supports lead-free reflow soldering per J-STD-020. Its matte tin-plated leads meet solderability requirements, and its MSL Level 1 classification means no dry-pack or baking is required prior to assembly. Peak reflow temperature up to 260°C is supported, consistent with standard Pb-free process profiles. The ES3HB M4G package remains mechanically stable under repeated thermal cycling.
What is the reverse recovery time (trr) specification for ES3HB M4G?
The ES3HB M4G has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table and applies across the full operating temperature range. The ES3HB M4G's 35 ns trr enables efficient operation in 200–500 kHz switching topologies while limiting diode-induced voltage overshoot and EMI.
Is ES3HB M4G halogen-free and RoHS compliant?
Yes, ES3HB M4G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all homogeneous materials meet EU Directive 2011/65/EU requirements. This compliance is documented in TSC's material declarations and applies to all production lots of ES3HB M4G.
How does the forward voltage of ES3HB M4G vary with temperature?
The forward voltage of ES3HB M4G decreases with rising junction temperature: at 1.5A, VF drops from 1.11V at 25°C to 0.85V at 125°C. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss at elevated temperatures. The ES3HB M4G maintains this behavior consistently across its rated current range, as validated in the Typical Forward Characteristics curves.
