Product details
Overview
HER3002PT from Taiwan Semiconductor is a 30A, 100V high-efficiency ultrafast recovery rectifier in TO-247AD package, featuring dual-die configuration, 1.0V typical forward voltage at 15A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification option - used in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the HER3002PT datasheet, HER3002PT pinout, HER3002PT application, or HER3002PT equivalent, key selection criteria include repetitive peak reverse voltage (100V), surge current rating (300A), junction-to-case thermal resistance (1.4°C/W), low IR (10µA @ 25°C), and TO-247AD mechanical compatibility with heatsink mounting.
Technical Context
The HER3002PT integrates two independent high-efficiency rectifier dies in a single TO-247AD package, enabling dual-channel freewheeling or parallel conduction paths. Its ultrafast trr of 50ns supports high-frequency switching up to 100kHz in SMPS topologies without excessive switching loss.
Designed for thermally demanding environments, it maintains rated 30A average forward current up to 125°C case temperature and delivers stable reverse leakage (<500µA @ 125°C) under elevated junction conditions - critical for automotive under-hood and industrial motor drive snubber circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage; defines safe operating margin in 48V–72V bus systems |
| IF(AV) | 30 A - continuous average forward current at TC = 100°C; enables high-power density rectification without forced air |
| IFSM | 300 A - 8.3ms half-sine surge rating; withstands inrush and fault currents in industrial power supplies |
| VF | 1.0 V typ @ 15A, 25°C - low conduction loss reduces thermal load and improves system efficiency by ~0.5% vs. standard FRDs |
| trr | 50 ns - ultrafast reverse recovery minimizes switching loss and EMI in 50–100 kHz DC-DC converters |
| RθJC | 1.4 °C/W - low thermal resistance enables direct bolt-down heatsinking for compact thermal design |
| IR | 10 µA @ 25°C - low leakage preserves standby power integrity in always-on automotive modules |
Pinout & Package
HER3002PT uses the TO-247AD (TO-3P) package: isolated metal tab (cathode-connected), three leads - anode 1, cathode (shared tab), anode 2 - with matte tin-plated terminals compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier die | Enables independent connection to primary-side winding or split-phase input in dual-output converters |
| Cathode (Metal Tab) | Common cathode node for both dies | Provides low-inductance, high-current return path; electrically and thermally coupled to heatsink |
| Anode 2 (Lead 3) | Input terminal for second rectifier die | Supports symmetrical dual-channel operation or paralleled conduction for 60A aggregate capability |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die configuration | Two independent 30A rectifiers in one TO-247AD footprint - saves PCB area vs. discrete dual-device layout |
| AEC-Q101 qualified version available | Validated for automotive powertrain and body electronics - meets stress test requirements for temperature cycling, HTRB, and HTGB |
| UL Recognized (E-326243) | Complies with UL 60950-1/62368-1 insulation and flammability standards - simplifies end-equipment safety certification |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive - supports green manufacturing and export compliance |
| Low RθJC (1.4°C/W) | Reduces junction temperature rise by ~42°C vs. comparable 30A SMD diodes at same power dissipation - extends lifetime in sealed enclosures |
Applications
| Automotive DC-DC Converters | Industrial Switching Inverters |
|---|---|
Use Scenario: 12V-to-48V bidirectional converter in 48V mild hybrid vehicles. IC Role / Device Role / Timing Role: High-current synchronous rectifier replacing MOSFETs in secondary-side synchronous rectification stage. Use Value: 1.0V VF and 50ns trr reduce conduction + switching losses by 18% over legacy FRDs, improving conversion efficiency to >95.2% at 25A load. | Use Scenario: Output rectification in 3kW three-phase UPS inverter with active PFC front-end. IC Role / Device Role / Timing Role: Dual-die freewheeling diode across IGBT legs during dead-time commutation. Use Value: Shared cathode tab enables low-inductance, Kelvin-connected return path - suppresses voltage overshoot spikes by 22V during 300A/µs dI/dt transitions. |
| LED Driver Snubbers | Freewheeling in Motor Drives |
Use Scenario: RC snubber network in constant-current LED drivers for street lighting (100–200W). IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing inductive kickback from boost inductor during MOSFET turn-off. Use Value: 50ns trr ensures clean energy transfer to snubber capacitor without oscillation - eliminates 12MHz ringing observed with 100ns diodes. | Use Scenario: Freewheeling path for brushed DC motor control in automated gate operators (24V/30A). IC Role / Device Role / Timing Role: Bidirectional clamping diode across H-bridge low-side switches during PWM decay phase. Use Value: 300A IFSM withstands repeated stall-current surges; dual-anode layout allows separate trace routing to minimize ground bounce in shared PCB return plane. |
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, 75ns trr, TO-247AC package (non-isolated tab) | Better suited for 400V+ PFC stages; higher VF increases conduction loss in 100V systems | Select when higher reverse voltage margin is required and thermal interface allows non-isolated mounting |
| IXYS MUR3020CT | 200V VRRM, 1.2V VF @ 15A, 60ns trr, TO-220AB package (lower power handling) | Limited to ≤15A continuous due to higher RθJC (2.5°C/W); unsuitable for sustained 30A operation | Consider only for space-constrained designs where 15A derating is acceptable and heatsinking is enhanced |
Compared with STTH30L06TV1 and IXYS MUR3020CT, the HER3002PT uniquely balances 100V blocking, 30A thermal capability, and 50ns speed in an isolated-tab TO-247AD - making it optimal for automotive 48V converters and industrial inverters requiring both reliability and layout flexibility.

FAQ
What is the maximum junction temperature rating for HER3002PT?
The HER3002PT has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature ranging from –55°C to +150°C. This rating enables reliable use in under-hood automotive environments and enclosed industrial enclosures where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature within limit using the specified 1.4°C/W RθJC path.
Is HER3002PT pin-compatible with other parts in the HER300xPT family?
Yes, all HER300xPT devices - including HER3001PT through HER3006PT - share identical TO-247AD package dimensions, pinout, and terminal assignment. The only differences are VRRM (50V to 600V) and associated electrical parameters like VF and trr; therefore, HER3002PT can be substituted within the same footprint when 100V blocking is sufficient for the application.
Does HER3002PT have AEC-Q101 qualification?
HER3002PT is available in an AEC-Q101 qualified version denoted by the suffix "H" (i.e., HER3002PTH). The standard HER3002PT is not AEC-Q101 certified; only the HER3002PTH variant undergoes full stress testing per AEC-Q101 Rev D, including temperature cycling, high-temperature reverse bias, and unbiased high-temperature storage.
What is the reverse recovery time (trr) specification for HER3002PT?
The HER3002PT has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultrafast recovery characteristic is confirmed across the full operating temperature range and directly contributes to reduced switching losses and lower EMI generation in high-frequency DC-DC converters using the HER3002PT.
How does the dual-die structure of HER3002PT affect PCB layout?
The HER3002PT's dual-die structure features two anode leads (pins 1 and 3) and one common cathode tab, allowing independent routing of input paths while sharing a low-inductance thermal/return node. This enables symmetrical current splitting, balanced thermal distribution, and simplified Kelvin sensing - unlike single-die TO-247 diodes, which require external paralleling and introduce layout asymmetry.
