Product details
Overview
3A60 from Taiwan Semiconductor is a 3A, 600V standard glass-passivated silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.1V max forward voltage at 3A, 120A non-repetitive surge capability, and AEC-Q101 qualification option. It serves as a primary AC/DC input rectifier in compact switching power supplies.
For engineers reviewing the 3A60 datasheet, 3A60 pinout, 3A60 application, or 3A60 equivalent, key selection criteria include its 600V VRRM rating, 17°C/W junction-to-lead thermal resistance, RoHS/halogen-free compliance, and suitability for automotive-grade DC-DC converters requiring high surge tolerance and low conduction loss.
Technical Context
This single-die standard rectifier operates with a PN junction structure and glass-passivated chip surface, enabling stable reverse blocking up to 600V and reliable operation from –55°C to +150°C junction temperature. Its low VF (≤1.1V @ 3A, 25°C) and low RθJL (17°C/W) support thermally constrained board layouts.
The device delivers 120A peak surge current under 8.3ms half-sine waveform and exhibits only 5µA max reverse leakage at 25°C - critical for maintaining efficiency in high-frequency switching topologies where leakage-induced standby loss matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines safe AC input voltage range in bridge or single-phase rectifiers. |
| IF | 3 A - Continuous average forward current rating; determines usable output power level in 12–24V DC-DC front-end stages. |
| IFSM | 120 A - Non-repetitive surge current capacity; enables robustness against line transients and inrush during cold start. |
| VF (max) | 1.1 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss; enables <3.3W dissipation at full load in TO-220-equivalent thermal conditions. |
| RθJL | 17 °C/W - Junction-to-lead thermal resistance; supports direct PCB copper pad heatsinking without external heatsink in ≤3A applications. |
| IR (max) | 5 µA @ 25°C - Reverse leakage current; ensures minimal standby power loss in offline SMPS standby circuits. |
| CJ | 27 pF @ 1MHz, 4V - Junction capacitance affects high-frequency switching noise and EMI filter design in PFC and flyback stages. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded plastic case with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002. Weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to AC input or transformer secondary; must handle full RMS current and transient surges. |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to bulk capacitor positive rail; polarity marking prevents reverse installation in high-voltage rectifier bridges. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reverse leakage performance and humidity resistance without hermetic sealing. |
| AEC-Q101 qualified version available (3A60H) | Validated for automotive under-hood environments including thermal cycling, vibration, and high-temperature bias stress. |
| UL 94V-0 molding compound | Meets flame-retardant safety requirements for industrial and consumer power supplies subject to regulatory certification. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth on leads, eliminating risk of short-circuit failure in high-reliability 10+ year deployments. |
| Halogen-free per IEC 61249-2-21 | Complies with environmental regulations for electronics used in EU, Japan, and North America markets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR360 | Ultrafast recovery (trr = 50ns), 600V, 3A; VF = 1.7V (higher conduction loss) | Better for high-frequency PFC stages; less suitable for low-loss linear-regulated outputs | Select when fast switching and reduced ringing outweigh VF penalty. |
| Vishay 1N5408 | 600V, 3A, standard recovery; VF = 1.2V; no AEC-Q101 or halogen-free options | Legacy industrial use only; lacks automotive qualification and modern environmental compliance | Acceptable for cost-sensitive non-automotive applications where regulatory compliance is not required. |
Compared with MUR360 and 1N5408, the 3A60 offers the lowest VF (1.1V), AEC-Q101 availability, and halogen-free construction - making it optimal for thermally constrained, automotive-qualified, or eco-compliant power supplies where conduction efficiency and long-term reliability are prioritized over ultrafast recovery.

FAQ
What is the maximum junction temperature rating for the 3A60?
The 3A60 has a maximum junction temperature (TJ) of +150°C, with an operational range from –55°C to +150°C. This rating allows reliable use in high-ambient environments such as enclosed power supplies or under-hood automotive locations when paired with appropriate PCB copper area for thermal dissipation. The 3A60 maintains specified electrical parameters within this full range.
Is the 3A60 available in an AEC-Q101 qualified version?
Yes - the 3A60H variant is AEC-Q101 qualified and marked with "H" in the ordering code. It undergoes extended stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST) to validate performance in automotive under-hood applications. The base 3A60 is not AEC-Q101 qualified.
What does the "3A60" marking on the device indicate?
The "3A60" marking on the 3A60 device indicates its nominal ratings: "3A" denotes the 3A average forward current, and "60" specifies the 600V repetitive peak reverse voltage (VRRM). This marking appears on the cathode-banded body and aligns with Taiwan Semiconductor's standardized coding for its DO-15 rectifier series.
What is the thermal resistance from junction to ambient for the 3A60?
The 3A60 has a junction-to-ambient thermal resistance (RθJA) of 52°C/W under standard JEDEC test conditions (single device on FR-4, 1-inch² copper pad). This value assumes minimal PCB copper; actual RθJA improves significantly with larger copper areas or thermal vias - a key design consideration for sustained 3A operation.
Does the 3A60 meet RoHS and halogen-free requirements?
Yes - the 3A60 is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These attributes support compliance with EU WEEE, China RoHS, and global green procurement policies.
