Product details
Overview
HER3001PT from Taiwan Semiconductor is a 30A, 50V high-efficiency ultrafast recovery rectifier diode in TO-247AD package, featuring 1.0V max forward voltage at 15A/25°C, 50ns reverse recovery time, and dual-die construction for enhanced thermal performance in high-frequency switching applications such as DC-DC converters and snubber circuits.
For engineers reviewing the HER3001PT datasheet, HER3001PT pinout, HER3001PT application, or HER3001PT equivalent, key selection criteria include its 50V VRRM, 300A IFSM, 1.4°C/W RθJC, AEC-Q101 qualification option (HER3001PTH), and UL recognition (E-326243) - all critical for automotive-grade power conversion design.
Technical Context
This device is a single-phase, dual-die ultrafast recovery rectifier optimized for high-current, high-frequency operation. Its 50ns trr and low 1.0V VF at 15A enable reduced switching losses in SMPS topologies, while the TO-247AD package supports direct heatsink mounting with 1.13 N·m max torque.
The HER3001PT operates across -55°C to +150°C junction temperature range and exhibits 10µA max IR at 25°C and 500µA at 125°C, ensuring stable blocking performance under thermal stress. Its 175pF junction capacitance at 1MHz/4V further supports fast transient response in snubber and freewheeling roles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06TV1 | 600V VRRM, 1.7V VF @ 15A, 60ns trr, TO-247 package | Higher voltage rating but higher conduction loss; suited for 400V+ PFC stages, not optimal for 50V systems | Select only if system requires >50V reverse margin or shares BOM with higher-voltage variants |
| IXYS MUR3050PT | 50V VRRM, 1.15V VF @ 15A, 35ns trr, TO-247 package | Faster recovery but higher forward drop; better for >1MHz resonant converters where trr dominates loss | Prefer when minimizing EMI is prioritized over conduction loss in compact high-frequency designs |
Compared with STTH30L06TV1 and IXYS MUR3050PT, the HER3001PT delivers the lowest VF among 50V 30A ultrafast rectifiers, making it optimal for efficiency-critical 12–48V DC-DC outputs where thermal headroom is constrained.

FAQ
What is the maximum junction temperature rating for the HER3001PT?
The HER3001PT has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This rating is validated per JEDEC standards and enables reliable use in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures exceed 85°C. The HER3001PT maintains specified electrical parameters within this full range.
Is the HER3001PT pin-compatible with other devices in the HER300xPT family?
Yes, the HER3001PT shares identical TO-247AD (TO-3P) mechanical footprint, pinout, and terminal assignment with all HER300xPT variants (HER3002PT through HER3006PT). This allows direct substitution in PCB layouts when voltage rating changes are acceptable - though electrical validation of VRRM, VF, and trr remains required for final design sign-off.
Does the HER3001PT meet automotive qualification standards?
The HER3001PT itself is not AEC-Q101 qualified; however, the HER3001PTH variant - identical in all electrical and thermal specifications - is fully AEC-Q101 qualified. Customers requiring automotive-grade reliability must specify HER3001PTH, which carries the same TO-247AD package, 50V rating, and 30A current capability as the base HER3001PT.
What is the reverse leakage current specification for the HER3001PT at elevated temperature?
The HER3001PT specifies a maximum reverse leakage current (IR) of 10 µA at 25°C and rated VR, rising to 500 µA at 125°C. This behavior is measured per JESD22-A115 and reflects intrinsic silicon characteristics - critical for maintaining efficiency in high-temperature snubber and freewheeling applications where leakage directly contributes to standby loss.
How does the dual-die construction of the HER3001PT improve thermal performance?
The HER3001PT uses dual-die construction to distribute 30A forward current across two parallel silicon dies within one TO-247AD package. This reduces localized heating, lowers effective junction-to-case thermal resistance to 1.4°C/W, and improves current-sharing stability under dynamic load conditions - directly enabling higher sustained power density than single-die 30A rectifiers with comparable RθJC.
