Taiwan Semiconductor Corporation HER153GH

Overview

HER153GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified silicon rectifier diode in DO-204AC (DO-15) package, rated for 200 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF), and 50 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (VF = 1.0 V at IF = 1.5 A, TJ = 25°C), fast reverse recovery time (trr = 50 ns), and operates up to 150°C junction temperature - ideal for automotive-grade DC-DC converters and switching-mode power supplies.

For engineers reviewing the HER153GH datasheet, HER153GH pinout, HER153GH application, or HER153GH equivalent, key selection criteria include its AEC-Q101 qualification, 200 V VRRM rating, 1.0 V VF at 1.5 A, 50 ns trr, DO-15 mechanical compatibility, and RoHS/halogen-free compliance for automotive and industrial power conversion designs.

Technical Context

This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time and low junction capacitance (35 pF at 1 MHz, VR = 4.0 V) support efficient operation in SMPS topologies where switching losses must be minimized.

The HER153GH shares the same DO-204AC (DO-15) package and thermal resistance (RθJA = 60°C/W) as the full HER15xG family, with cathode polarity indicated by a band. It is rated for -55°C to +150°C operating and storage temperature range, meeting JESD201 Class 2 whisker resistance and UL 94V-0 molding compound requirements.

FAQ

What does the 'H' suffix in HER153GH signify?

The 'H' suffix in HER153GH indicates AEC-Q101 qualification - a rigorous stress-test standard for discrete semiconductors used in automotive electronics. This certification confirms that the HER153GH has passed temperature cycling, humidity bias, mechanical shock, and high-temperature reverse bias tests required for under-hood and safety-critical applications. The base part HER153G lacks this qualification.

Is HER153GH pin-compatible with other DO-15 rectifiers like 1N4007 or FR153?

Yes, HER153GH uses the standard DO-204AC (DO-15) axial package with identical lead spacing and dimensions as 1N4007 and FR153, enabling direct physical replacement. However, HER153GH offers significantly lower VF (1.0 V vs. ~1.1 V) and faster trr (50 ns vs. >200 ns), delivering measurable efficiency gains in high-frequency circuits where those parameters matter.

What is the maximum allowable case temperature for HER153GH in continuous operation?

The HER153GH has a maximum junction temperature (TJ) of +150°C, but case temperature depends on thermal design. With RθJA = 60°C/W and IF = 1.5 A, typical power dissipation is ~1.5 W, implying a 90°C rise above ambient. For reliable continuous operation at full current, keep case temperature below 100°C using adequate PCB copper area or minimal airflow - verified via thermal simulation or thermocouple measurement on the HER153GH body.

Does HER153GH support reflow soldering, or is it lead-free wave-solder only?

HER153GH features pure tin-plated leads compliant with J-STD-002 for solderability, and its DO-15 package is rated for standard lead-free reflow profiles (peak ≤ 260°C, 60 s max). However, due to axial lead geometry and thermal mass, controlled preheat and soak phases are recommended to avoid thermal shock. Reflow is viable for automated assembly; hand-soldering requires <350°C tip temperature and <3 s contact time per lead to protect the HER153GH junction.

How does HER153GH's 50 ns reverse recovery time impact EMI in a 500 kHz SMPS design?

HER153GH's 50 ns trr reduces high-frequency ringing during turn-off, lowering broadband EMI emissions above 30 MHz compared to slower diodes like FR153 (trr > 250 ns). In a 500 kHz SMPS, this allows smaller input EMI filters and less ferrite bead loading on the HER153GH anode/cathode traces - directly improving conducted emission test margins without changing layout or control loop tuning.
