Product details
Overview
ES3HBHR5G from Taiwan Semiconductor is a 3A, 500V 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 secondary-side rectification.
For engineers reviewing the ES3HBHR5G datasheet, ES3HBHR5G pinout, ES3HBHR5G application, or ES3HBHR5G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 24°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for automated SMT assembly.
Technical Context
This discrete silicon diode uses a glass-passivated PN junction optimized for high-efficiency switching operation. Its super-fast recovery (trr ≤ 35 ns) minimizes switching losses in DC-DC converters operating above 100 kHz, while low VF at elevated temperature (0.99V @ 3A/125°C) sustains conduction efficiency under thermal stress.
The device is rated for 100A non-repetitive surge current (IFSM) and operates across –55°C to +150°C junction range. Thermal performance is characterized on a 10mm × 10mm copper pad PCB, with RθJA = 84°C/W and RθJC = 26°C/W supporting compact power stage layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - Maximum repetitive reverse blocking voltage; defines safe operating margin in 375–450V DC bus applications. |
| IF | 3 A - Continuous average forward current; supports up to 36W dissipation at 125°C ambient with proper heatsinking. |
| trr | 35 ns - Reverse recovery time; enables efficient operation in 200–500 kHz SMPS topologies without excessive ringing or EMI. |
| VF @ 3A/25°C | 1.24 V - Forward voltage drop; determines conduction loss (3.72 W at full load) and thermal design baseline. |
| CJ | 34 pF - Junction capacitance at 1 MHz / 4V; impacts high-frequency switching node impedance and snubber sizing. |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance; enables direct thermal path to PCB copper for passive cooling in space-constrained designs. |
| MSL | Level 1 - Moisture sensitivity per J-STD-020; allows unlimited floor life and standard reflow without baking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 1.25V VF @ 3A/25°C, trr = 30 ns, same DO-214AA package | Higher voltage margin suits 400V DC bus designs; slightly faster recovery but higher VF increases conduction loss | Select when system requires ≥550V blocking or tighter trr tolerance; verify thermal derating due to higher VF |
| SB350-E3/5BT | 50V VRRM, 0.55V VF @ 3A/25°C, trr = 35 ns, same DO-214AA package | Optimized for low-voltage, high-current outputs (e.g., 5V/3A); insufficient for 500V applications | Use only in sub-100V output stages where ultra-low VF dominates efficiency; not interchangeable with ES3HBHR5G in 500V systems |
Compared with STTH3L06S and SB350-E3/5BT, ES3HBHR5G delivers optimal balance of 500V blocking, 1.24V conduction loss, and 35ns recovery for mid-range SMPS - making it preferred for 375–450V DC bus applications where voltage margin and thermal performance are both critical.

FAQ
What is the maximum junction temperature rating for ES3HBHR5G?
The ES3HBHR5G has a maximum junction temperature (TJ) rating of +150°C, with operational capability down to –55°C. This wide range supports deployment in thermally demanding environments such as enclosed industrial power supplies or high-density server PSUs where ambient temperatures exceed 85°C. The device's RθJL of 24°C/W enables effective heat transfer to the PCB, allowing sustained operation near its thermal limit when properly mounted on adequate copper area.
Does ES3HBHR5G meet lead-free and RoHS requirements?
Yes, ES3HBHR5G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Its matte tin-plated leads are solderable per J-STD-002, and the molding compound meets UL 94V-0 flammability standards. These attributes make ES3HBHR5G suitable for global electronics manufacturing, including consumer, industrial, and computing applications subject to environmental compliance mandates.
What is the reverse recovery time (trr) specification for ES3HBHR5G and how is it measured?
The ES3HBHR5G has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A per the manufacturer's test methodology. This parameter reflects the diode's ability to transition rapidly from conduction to blocking state, directly impacting switching losses and EMI in high-frequency converters. The 35 ns value is confirmed across the full temperature range and supports stable operation in 200–500 kHz topologies without requiring external snubbers.
Can ES3HBHR5G be used as a direct replacement for ES3GB or ES3JB in existing designs?
ES3HBHR5G is not a direct replacement for ES3GB (400V) or ES3JB (600V) due to its specific 500V VRRM rating. While all share the same DO-214AA package and thermal characteristics, substituting across voltage grades requires verification of system-level voltage stress margins. For example, using ES3HBHR5G in an ES3JB-design may risk overvoltage failure in transient conditions, whereas using it in place of ES3GB may unnecessarily increase VF and conduction loss without benefit.
What is the junction capacitance (CJ) of ES3HBHR5G and why does it matter?
The ES3HBHR5G exhibits a typical junction capacitance (CJ) of 34 pF at 1 MHz and 4.0 V reverse bias. This parameter influences high-frequency behavior - particularly in switching nodes - by affecting ringing amplitude, EMI generation, and snubber component selection. In fast-switching converters, lower CJ reduces displacement current during voltage transitions, improving efficiency and easing EMI filter design. The 34 pF value is among the lowest in the ES3x series, reflecting optimization for high-frequency rectification.
