Product details
Overview
HER156G from Taiwan Semiconductor is a high-efficiency, glass-passivated single-die silicon rectifier diode rated for 1.5A average forward current, 600V repetitive peak reverse voltage (VRRM), and 50A surge current (IFSM), used in DC-DC converters and switching-mode power supplies where low forward voltage drop and fast recovery are critical.
For engineers reviewing the HER156G datasheet, HER156G pinout, HER156G application, or HER156G equivalent, key selection factors include its 1.7V max forward voltage at 1.5A/25°C, 75ns reverse recovery time, 20pF junction capacitance at 1MHz/4V, DO-204AC (DO-15) package, and AEC-Q101 qualification availability in variant HER156GH.
Technical Context
The HER156G employs a planar passivated junction structure with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Its thermal resistance (RθJA) is 60°C/W, enabling operation up to 150°C junction temperature under defined PCB layout conditions.
This device operates as a unidirectional, single-anode/cathode rectifier with polarity indicated by a cathode band. It delivers low power loss via 1.7V typical VF at rated current and exhibits stable reverse leakage (≤5µA at 25°C, ≤150µA at 125°C) across its 600V VRRM rating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | 600V VRRM, 1.1A IF(AV), 50ns trr, TO-220AC package | Lower current rating; requires heatsink; faster recovery but lower surge tolerance (30A IFSM) | Prefer when board space allows TO-220 and ultra-low trr is prioritized over surge robustness |
| ES1J | 600V VRRM, 1A IF(AV), 35ns trr, DO-204AL (DO-41) package | Lower current and surge rating (30A IFSM); smaller DO-41 footprint; higher VF (~1.7V same test condition) | Select for cost-sensitive, lower-power (<15W) applications where DO-41 fits existing layout |
Compared with STTH1L60S and ES1J, HER156G uniquely balances 1.5A current, 50A surge, 75ns recovery, and DO-15 manufacturability-making it optimal for mid-power industrial SMPS where reliability and assembly compatibility are co-priorities.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HER156G?
The HER156G has a VRRM rating of 600 V, meaning it reliably blocks reverse voltages up to this level without breakdown under repetitive conditions. This value is fixed per the ordering row HER156G–HER158G and confirmed in the Absolute Maximum Ratings table. The HER156G datasheet specifies no derating required below 150°C junction temperature for this parameter.
Is HER156G AEC-Q101 qualified?
The base HER156G is not AEC-Q101 qualified; however, the variant HER156GH is explicitly marked as AEC-Q101 qualified in the Ordering Information section. HER156GH undergoes additional stress testing including HTOL, temperature cycling, and HTRB, making it suitable for automotive under-hood applications where HER156G alone would not be approved.
What is the forward voltage (VF) of HER156G at 1.5A and 25°C?
The HER156G exhibits a maximum forward voltage of 1.7 V at 1.5 A and TJ = 25°C, as specified in the Electrical Specifications table under "Forward voltage(1)". This value is measured using a pulse test with 0.3 ms pulse width and is representative of conduction loss under typical switching power supply operating conditions.
What package type does HER156G use, and what are its mechanical features?
HER156G uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include UL 94V-0 compliant molding compound, pure tin-plated leads meeting J-STD-002 solderability, JESD201 Class 2 whisker resistance, cathode polarity marking, and an approximate weight of 0.400 g. Dimensions conform to standard DO-15 outline drawings provided in the datasheet.
How does the reverse recovery time (trr) of HER156G compare to lower-voltage HER15xG variants?
HER156G has a maximum trr of 75 ns, matching HER157G and HER158G, while HER151G–HER155G are rated at 50 ns max. This increase reflects trade-offs in junction design for higher VRRM ratings: wider depletion regions in 600–1000V devices inherently slow carrier recombination, resulting in longer recovery times despite identical process technology.
