Product details
Overview
HER605G B0G from Taiwan Semiconductor is a high-efficiency, glass-passivated silicon rectifier diode in R-6 package, rated for 400 V repetitive peak reverse voltage (VRRM), 6 A average forward current (IF), and 150 A surge current (IFSM). It delivers low forward voltage drop (VF = 1.3 V at 6 A, 25°C) and fast reverse recovery time (trr = 50 ns), making it suitable for high-frequency switching power supplies in industrial DC-DC converters.
For engineers reviewing the HER605G B0G datasheet, HER605G B0G pinout, HER605G B0G application, or HER605G B0G equivalent, key selection criteria include its 400 V VRRM rating, 1.3 V VF at full load, 50 ns trr, R-6 package thermal resistance (RθJA = 37°C/W), and AEC-Q101 qualification eligibility via H-suffix variants.
Technical Context
This device is a single-die, standard recovery rectifier optimized for high-current, medium-voltage switching applications. Its glass passivation ensures stable junction performance under thermal cycling, while the R-6 molded package supports high surge robustness and meets UL 94V-0 flammability requirements.
The HER605G B0G operates across –55°C to +150°C junction temperature range with 10 µA max reverse leakage at 25°C and 200 µA at 125°C. Its 80 pF junction capacitance at 1 MHz / 4 V enables predictable high-frequency behavior in snubberless or lightly snubbed topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 600 V VRRM, 1.7 V VF @ 6 A, TO-220AC package, RθJA ≈ 40°C/W | Higher voltage margin but higher conduction loss; requires larger heatsink due to TO-220 thermal path | Preferred where 600 V blocking is mandatory and board space allows through-hole mounting |
| ON Semi MUR640 | 400 V VRRM, 1.3 V VF @ 6 A, same R-6 package, trr = 50 ns, RoHS-compliant | Functionally identical electrical specs and footprint; differs only in manufacturer qualification and traceability | Drop-in alternative when dual-sourcing or supply chain diversification is required |
Compared with STTH6L06S, HER605G B0G offers lower VF and smaller R-6 footprint; compared with MUR640, it shares identical ratings but provides Taiwan Semiconductor's AEC-Q101-qualified variant path and distinct date-code marking scheme.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HER605G B0G?
The HER605G B0G has a VRRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104), and is specific to the HER605G variant-not extrapolated from adjacent part numbers.
Does HER605G B0G have AEC-Q101 qualification?
The HER605G B0G itself is not AEC-Q101 qualified; however, the HER605GH variant (same electrical specs, H-suffix) is explicitly qualified per AEC-Q101. The B0G suffix indicates ammo box packaging (700 units), not qualification status. Engineers requiring automotive-grade assurance must specify HER605GH.
What is the forward voltage drop (VF) of HER605G B0G at rated current?
The HER605G B0G exhibits a maximum forward voltage drop of 1.3 V at 6 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design.
What package type does HER605G B0G use, and what are its key mechanical properties?
HER605G B0G uses the R-6 axial-leaded package: UL 94V-0 compliant molding compound, pure tin-plated leads solderable per J-STD-002, cathode polarity indicated by band, and approximate weight of 1.65 g. Its RθJA is 37°C/W, defining thermal interface requirements for PCB layout.
How does the reverse recovery time (trr) of HER605G B0G compare to HER606G?
The HER605G B0G has a trr of 50 ns, while HER606G is rated at 75 ns. This difference arises from internal die optimization for lower VRRM (400 V vs. 600 V), resulting in faster carrier recombination and reduced switching loss in mid-voltage SMPS applications.
