Product details
Overview
HER601-T from Diodes Incorporated is a 6.0A, 50V high-efficiency axial-lead rectifier diode with 1.2V forward voltage at 6.0A DC, 250A surge capability, and 60ns reverse recovery time-used in offline AC/DC power supplies, switch-mode adapters, and industrial motor drive front-end rectification.
For engineers reviewing the HER601-T datasheet, HER601-T pinout, HER601-T application, or HER601-T equivalent, key selection criteria include peak repetitive reverse voltage (50 V), average forward current (6.0 A), surge rating (250 A @ 8.3 ms), reverse recovery time (60 ns), and thermal derating behavior per Fig. 1.
Technical Context
This device is a silicon planar epitaxial high-efficiency rectifier optimized for fast switching and low conduction loss in single-phase bridge or half-wave configurations. Its 60 ns reverse recovery time and 1.2 V VF at 6.0 A enable reduced switching losses in 50/60 Hz and higher-frequency line-frequency rectification stages.
The R-6 package supports axial mounting with 9.5 mm lead length and UL 94V-0 flammability rating. Thermal resistance (RJA) is not specified in the datasheet, but Fig. 1 shows two derating curves-"A" for ground-plane PCBs (25 mm² copper) and "B" for standard mounting-indicating design-dependent thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive peak reverse voltage; defines safe blocking capability in AC line applications. |
| I(AV) | 6.0 A - Average forward rectified current at 25°C ambient; requires thermal derating above 55°C per Fig. 1. |
| IFSM | 250 A - Non-repetitive surge current for 8.3 ms half-sine; supports inrush tolerance in transformer-coupled supplies. |
| VF | 1.2 V @ 6.0 A DC - Forward voltage drop directly impacts conduction loss and thermal rise in continuous operation. |
| TRR | 60 ns - Reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, IRR = 0.25 A; enables faster turn-off than general-purpose rectifiers. |
| IR | 10 µA @ 25°C - Maximum DC reverse leakage at rated VDC; critical for low-power standby and high-impedance bias networks. |
Pinout & Package
HER601-T uses an axial-lead R-6 package (JEDEC DO-41 variant) with cathode indicated by a color band. Leads are solderable per MIL-STD-202, Method 208. Approximate weight: 1.7 g. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input / Positive half-cycle entry | Connected to transformer secondary or AC line phase; carries full forward current during conduction. |
| Cathode | DC output / Rectified positive rail | Delivers pulsating DC to filter capacitor; polarity marked by color band on body. |
Key Features
| Feature | Design Value |
|---|---|
| High surge current capability | 250 A non-repetitive peak supports transformer inrush and capacitor charging surges without failure. |
| Low forward voltage drop | 1.2 V at 6.0 A reduces conduction loss and improves efficiency in high-current linear or SMPS front ends. |
| Fast reverse recovery | 60 ns recovery time minimizes switching loss and EMI generation in higher-frequency rectifier topologies. |
| UL 94V-0 plastic case | Flame-retardant encapsulation meets safety standards for enclosed power supply designs. |
Applications
| AC/DC Power Adapters | Industrial Motor Drive Front Ends |
|---|---|
Use Scenario: 50/60 Hz rectification in wall-mounted AC/DC adapters delivering 5–24 V DC at up to 5 A. IC Role / Device Role / Timing Role: High-current half-wave or bridge rectifier converting mains AC to unregulated DC bus. Use Value: 6.0 A average current rating and 250 A surge tolerance ensure reliable operation under load transients and cold-start conditions. | Use Scenario: Input rectification stage of three-phase motor drive auxiliary power supply feeding control logic. IC Role / Device Role / Timing Role: Single-phase rectifier supplying isolated +15 V/-15 V rails for gate drivers and op-amps. Use Value: Low 1.2 V forward drop minimizes heat buildup in compact enclosures where forced air cooling is unavailable. |
| UPS Battery Charging Circuits | LED Driver Input Stages |
Use Scenario: Mains-powered battery charger in offline UPS systems with automatic AC/DC switchover. IC Role / Device Role / Timing Role: Primary-side rectifier in transformer-isolated charger topology handling 6 A continuous charge current.

Use Value: UL 94V-0 housing satisfies end-equipment fire safety requirements for outdoor and Class 2 installations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HER101G (ON Semiconductor) | Same 50 V VRRM, but lower I(AV) = 1.0 A and IFSM = 30 A; TO-220AC package. | Suitable only for low-current signal or bias rectification-not for 6 A power conversion. | Select HER101G only when space-constrained PCB layout permits TO-220 mounting and current demand is ≤1 A. |
| UF4001 (STMicroelectronics) | 50 V VRRM, 1.0 A I(AV), 30 A IFSM, 50 ns TRR; ultrafast but lower current rating. | Used in snubber networks and low-power flyback outputs-not primary rectification. | Choose UF4001 where speed dominates over current capacity, e.g., clamp diodes or high-frequency auxiliary windings. |
Compared with HER101G and UF4001, HER601-T uniquely delivers 6.0 A average current in an axial R-6 package with 250 A surge margin-making it irreplaceable for high-power, cost-sensitive line-frequency rectification where TO-220 footprint or thermal vias are impractical.

FAQ
What is the maximum operating temperature for HER601-T?
The HER601-T has a junction and storage temperature range of –65°C to +150°C. Its forward current must be derated above 55°C case temperature per Fig. 1, with two defined derating curves depending on PCB copper area-ground plane (Derating A) or standard mounting (Derating B).
Is HER601-T suitable for use in a full-wave bridge configuration?
Yes-HER601-T is commonly used in discrete full-wave bridge rectifiers due to its 6.0 A average current rating, 250 A surge capability, and axial R-6 package symmetry. Four units can form a 6 A bridge with matched thermal characteristics and low VF consistency across devices.
How does the 60 ns reverse recovery time impact EMI performance?
The 60 ns TRR reduces high-frequency ringing during turn-off, lowering conducted EMI in the 1–30 MHz range. This allows simpler input filtering compared to slower rectifiers like 1N4007 (TRR > 2 µs), especially in compact adapter designs with limited board space for ferrites and capacitors.
Can HER601-T replace a 1N5408 in a 3 A power supply?
Yes-with significant margin: HER601-T offers 6.0 A average current vs. 1N5408's 3 A, plus lower VF (1.2 V vs. ~1.1 V at 3 A) and faster recovery (60 ns vs. ~2 µs). It improves efficiency and thermal headroom, though physical fit must be verified-both use axial leads but HER601-T's R-6 case is slightly longer (9.1 mm max vs. DO-201AD's 9.5 mm).
