Product details
Overview
HER107G B0G from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode rated for 800 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF), and 30 A non-repetitive surge current (IFSM), used as a freewheeling or output rectifier in switching-mode power supplies.
For engineers reviewing the HER107G B0G datasheet, HER107G B0G pinout, HER107G B0G application, or HER107G B0G equivalent, key selection criteria include its 1.7 V forward voltage at 1 A, 75 ns reverse recovery time, 10 pF junction capacitance at 4 V, DO-41 package thermal resistance (RθJA = 60 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a single-die, unidirectional, standard recovery rectifier with a PN junction fabricated using glass passivation for enhanced moisture and contamination resistance. Its 800 V VRRM rating and 150 °C maximum junction temperature support operation in high-voltage DC-DC converters and industrial inverters where thermal stability and voltage margin are critical.
The HER107G B0G exhibits low reverse leakage (≤5 µA at 25 °C, ≤150 µA at 125 °C) and fast switching performance (trr = 75 ns), enabling efficient energy transfer in flyback and forward converter topologies without requiring snubber networks in moderate-frequency designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports input rectification up to 565 V AC RMS or 800 V DC bus applications |
| IF(AV) | 1 A - continuous conduction mode operation in low-to-medium power SMPS (≤15 W) |
| VF @ 1 A | 1.7 V - contributes ~1.7 W conduction loss at full load; requires thermal derating above 75 °C ambient |
| trr | 75 ns - enables switching frequencies up to ~200 kHz before significant switching loss dominates |
| RθJA | 60 °C/W - mandates minimum 0.25 in² copper pad for safe 1 A operation at 70 °C ambient |
| IR @ 25°C | ≤5 µA - ensures minimal standby power loss in battery-backed or energy-harvesting systems |
| Package | DO-204AL (DO-41) - through-hole mounting compatible with legacy PCB assembly and manual rework |
Pinout & Package
DO-204AL (DO-41) axial-leaded package with cathode indicated by a painted band; leads are pure tin-plated and J-STD-002 solderable. No internal pins-two terminals only: anode and cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node) |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; connects to output filter capacitor positive rail or load return path |
Key Features
| Feature | Design Value |

| JESD 201 Class 2 whisker resistance | Eliminates tin whisker growth risk in long-life telecom or infrastructure equipment |
Applications
| DC–DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12 V/1 A flyback converter powering industrial sensors. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; blocks reverse voltage during MOSFET off-time. Use Value: 1.7 V VF minimizes conduction loss; 75 ns trr avoids cross-conduction losses with synchronous FETs operating at 100–150 kHz. | Use Scenario: Freewheeling path across inductive motor windings in 24 V H-bridge inverter for HVAC actuators. IC Role / Device Role / Timing Role: Provides low-impedance recirculation path when PWM switches turn off, clamping inductive kickback. Use Value: 30 A IFSM withstands motor stall surges; 800 V VRRM provides 2× safety margin over 24 V bus transients. |
| Automotive Body Control Module Power Supply | Industrial AC–DC Auxiliary Supply |
Use Scenario: Input rectifier in 12 V auxiliary supply handling cold-crank (4.5 V) to load-dump (40 V) conditions in BCM. IC Role / Device Role / Timing Role: Front-end bridge or half-wave rectifier feeding buck controller; blocks reverse polarity and line transients. Use Value: AEC-Q101 qualification ensures reliability across -40 to +125 °C; glass passivation resists under-hood condensation. | Use Scenario: Primary-side rectifier in universal-input (85–265 V AC) 5 V/0.5 A auxiliary supply for PLC I/O modules. IC Role / Device Role / Timing Role: Converts AC line to high-voltage DC bus for offline controller IC; handles 30 A surge during inrush. Use Value: 60 °C/W RθJA allows natural convection cooling on FR4; DO-41 footprint simplifies legacy board reuse. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R08 | Same VRRM (800 V), IF (1 A), but VF = 1.85 V (higher loss); trr = 70 ns; TO-220AC package | Requires heatsink for >0.5 A; unsuitable for space-constrained DO-41 layouts | Select if higher surge rating (60 A IFSM) or surface-mount compatibility is needed |
| ON Semi MUR108E | VRRM = 800 V, IF = 1 A, VF = 1.75 V, trr = 75 ns; same DO-41 package; no AEC-Q101 | Lacks automotive qualification; IR = 10 µA @ 25 °C (double HER107G B0G's leakage) | Select for cost-sensitive industrial use where AEC-Q101 is not required |
Compared with STTH1R08 and MUR108E, HER107G B0G offers the lowest forward voltage among DO-41 800 V rectifiers with AEC-Q101 validation, making it optimal for thermally constrained automotive and industrial power supplies where reliability and efficiency are jointly prioritized.

FAQ
What is the maximum junction temperature rating for HER107G B0G?
The HER107G B0G has a maximum junction temperature (TJ) of +150 °C, verified per JEDEC JESD22-A108. This rating allows operation in sealed enclosures or high-ambient environments such as automotive engine compartments or industrial control cabinets, provided thermal design maintains TJ ≤ 150 °C under worst-case load and ambient conditions. The HER107G B0G datasheet specifies derating curves confirming usable current down to zero at 150 °C ambient.
Does HER107G B0G meet AEC-Q101 requirements?
Yes, HER107G B0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's L2104 datasheet revision and ordering code suffix "B0G", which explicitly denotes AEC-Q101 compliance. Testing includes high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). This qualification makes HER107G B0G suitable for automotive body electronics, infotainment power rails, and ADAS auxiliary supplies.
What is the reverse recovery time (trr) of HER107G B0G and how does it affect circuit performance?
The HER107G B0G has a reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value enables reliable operation in switching power supplies up to ~200 kHz without excessive switching loss or EMI generation. At higher frequencies, trr contributes to overlap conduction loss; therefore, HER107G B0G is best suited for 50–150 kHz flyback or forward converters where its 1.7 V VF and 800 V VRRM provide optimal trade-off between conduction and switching efficiency.
Is HER107G B0G halogen-free and RoHS compliant?
Yes, HER107G B0G uses a halogen-free molding compound compliant with IEC 61249-2-21 and is fully RoHS 2011/65/EU compliant. Lead finish is pure tin, meeting J-STD-002 solderability requirements. These environmental qualifications are documented in Taiwan Semiconductor's official HER101G–HER108G datasheet (Version L2104) and supported by material declarations available upon request from Aetrix Electronics.
What packaging options are available for HER107G B0G?
HER107G B0G is supplied in DO-204AL (DO-41) package with two packing options: 5,000 units per tape-and-reel (ordering code HER107G B0G) and 3,000 units per ammo box (ordering code HER107G B0G A0G). Both variants share identical electrical and thermal specifications; the choice depends on SMT line compatibility (tape-and-reel) or manual/hand-soldering workflows (ammo box).
