Product details

Overview

HER152GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified silicon rectifier diode in DO-204AC (DO-15) package, rated for 100 V repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F), and 50 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (1.0 V at 1.5 A, 25°C) and fast reverse recovery time (50 ns), making it suitable for switching-mode power supplies in automotive and industrial environments.

For engineers reviewing the HER152GH datasheet, HER152GH pinout, HER152GH application, or HER152GH equivalent, key selection criteria include its AEC-Q101 qualification, 100 V V_RRM, 1.0 V V_F at rated current, 50 ns t_rr, and DO-15 mechanical compatibility with standard through-hole PCB layouts.

Technical Context

The HER152GH employs a glass-passivated single-die PN junction optimized for high-efficiency rectification in DC–DC converters and freewheeling paths. Its thermal resistance (R_θJA = 60°C/W) and 150°C maximum junction temperature support operation under sustained load in compact enclosures.

Designed for switching-mode applications, it exhibits low junction capacitance (35 pF at 4 V, 1 MHz) and controlled reverse recovery behavior-critical for minimizing switching losses and EMI in 50–500 kHz power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum reverse blocking voltage before breakdown; defines usable input voltage range in buck/boost/flyback topologies.
I_F	1.5 A - Continuous average forward current rating; determines steady-state power handling without derating at 25°C ambient.
V_F	1.0 V @ 1.5 A, 25°C - Low conduction loss enables >92% efficiency in 12 V output converters at full load.
t_rr	50 ns - Fast recovery reduces switching transition losses and limits voltage overshoot during turn-off in hard-switched circuits.
I_FSM	50 A - Withstands short-duration inrush or fault currents (8.3 ms half-sine), supporting robust startup and overload protection.
R_θJA	60°C/W - Thermal impedance from junction to ambient; requires ≥120 mm² copper pad for full 1.5 A operation at 70°C ambient.
Junction temp.	−55°C to +150°C - Enables deployment in under-hood automotive modules and industrial control cabinets without active cooling.

Pinout & Package

HER152GH uses the DO-204AC (DO-15) axial-leaded package with cathode indicated by a band. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.

FAQ

What is the peak repetitive reverse voltage rating for HER152GH?

The HER152GH has a repetitive peak reverse voltage (V_RRM) rating of 100 V. This value is fixed for the HER152G variant and confirmed in the absolute maximum ratings table of the official Taiwan Semiconductor datasheet (Version I2105). Exceeding this voltage risks irreversible junction breakdown. The "2" in HER152GH directly corresponds to the 100 V rating per the family's numbering scheme.

Is HER152GH AEC-Q101 qualified, and what does the "H" suffix indicate?

Yes, HER152GH is AEC-Q101 qualified-the "H" suffix explicitly denotes qualification per the AEC-Q101 stress test standard for discrete semiconductors. This includes testing for temperature cycling, high-temperature reverse bias, and electrostatic discharge. The qualification applies to the full HER15xGH series, enabling use in automotive powertrain and chassis applications where reliability is mandated.

What is the forward voltage drop of HER152GH at its rated current?

The HER152GH exhibits a typical forward voltage (V_F) of 1.0 V at 1.5 A forward current and 25°C junction temperature, as specified in the electrical characteristics table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating. At elevated temperatures (e.g., 125°C), V_F decreases slightly (~0.85 V), improving conduction efficiency in thermally stressed operation.

Does HER152GH have a defined reverse recovery time, and how is it measured?

Yes, HER152GH has a maximum reverse recovery time (t_rr) of 50 ns, measured under the condition I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is validated using the test circuit shown in Figure 6 of the datasheet and reflects performance in high-frequency switching applications such as DC–DC converters operating above 100 kHz.

What package type and lead finish does HER152GH use?

HER152GH uses the DO-204AC (DO-15) axial-leaded package with pure tin-plated leads. The finish complies with J-STD-002 for solderability and passes JESD201 Class 2 whisker testing. Polarity is marked by a cathode band, and the molding compound meets UL 94V-0 flammability rating-ensuring compatibility with automated through-hole assembly and long-term reliability in humid environments.
