Product details
Overview
3A60H from Taiwan Semiconductor is a 3A, 600V AEC-Q101-qualified standard silicon rectifier diode in DO-204AC (DO-15) package, featuring 1.1V max forward voltage at 3A, 120A surge capability, and 17°C/W junction-to-lead thermal resistance. It serves as primary AC/DC input rectification in automotive-grade DC-DC converters.
For engineers reviewing the 3A60H datasheet, 3A60H pinout, 3A60H application, or 3A60H equivalent, key selection criteria include its AEC-Q101 qualification status, 600V repetitive peak reverse voltage, 120A IFSM rating, thermal resistance profile, and DO-15 mechanical compatibility with legacy through-hole power supply layouts.
Technical Context
The 3A60H is a single-die, glass-passivated PN-junction rectifier optimized for high-efficiency, high-surge industrial and automotive power conversion. Its 1.1V VF max at 3A and 5µA IR max at 25°C support low conduction loss and leakage-sensitive designs.
Thermally, it delivers RθJL = 17°C/W and RθJA = 52°C/W, enabling reliable operation up to 150°C junction temperature. Polarity is marked by cathode band; leads are pure tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe AC input voltage headroom in bridge or single-phase rectifiers |
| IF | 3 A - Continuous average forward current; sets baseline conduction capacity for 24–48V DC-DC front-end stages |
| IFSM | 120 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush and fault-current handling without bond-wire failure |
| VF | ≤1.1 V @ 3A, 25°C - Low forward drop reduces conduction loss and thermal stress in high-duty-cycle applications |
| RθJL | 17 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour or lead-frame thermal path |
| IR | ≤5 µA @ 600V, 25°C - Minimal reverse leakage ensures stable bus hold-up and low standby power in offline supplies |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS- and halogen-free compliant. Cathode indicated by band; leads tin-plated, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Input current entry point | Connects to AC source or transformer secondary; must withstand full surge and RMS current |
| Cathode (banded end) | Output current exit point | Feeds bulk capacitor or downstream converter; polarity marking prevents reverse-bias damage during assembly |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood and powertrain applications per stress test requirements including HTOL, TC, and HAST |
| Glass-passivated junction | Enhances moisture resistance and long-term reliability in humid or thermally cycling environments |
| Low VF (≤1.1 V) | Reduces power dissipation by ~0.33W vs. typical 1.4V diodes at 3A, lowering heatsink requirements |
| 120A IFSM rating | Withstands cold-start surges and short-circuit transients without parametric shift or catastrophic failure |
| UL 94V-0 molding compound | Meets flammability safety standards for enclosed power electronics in industrial and transportation systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, 1.15V VF max, TO-220AC package, no AEC-Q101 | Higher thermal mass but requires mounting hardware; not automotive-qualified | Select when higher power dissipation tolerance is needed and AEC-Q101 is not required |
| ON Semi MUR360 | 600V VRRM, 3A IF, 1.7V VF max, DO-15, no AEC-Q101, faster recovery (~50ns) | Higher VF increases conduction loss; faster recovery suits higher-frequency topologies but adds cost | Select only if fast recovery is mandatory and thermal budget allows 0.6V higher drop |
Compared with STTH3L06S and MUR360, the 3A60H uniquely combines AEC-Q101 qualification, DO-15 form factor, and 1.1V VF in a single offering-making it the preferred choice for space-constrained, automotive-compliant rectification where leaded reliability and thermal performance are prioritized over ultra-fast switching.

FAQ
What is the AEC-Q101 qualification status of the 3A60H?
The 3A60H is explicitly AEC-Q101 qualified per the manufacturer's documentation and ordering code suffix "H". This certification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-validating its suitability for automotive under-hood and powertrain applications. The 3A60H datasheet Version B2105 confirms this qualification.
What does the "H" suffix in 3A60H signify?
The "H" suffix in 3A60H denotes AEC-Q101 qualification, as specified in the Ordering Information section of the Taiwan Semiconductor datasheet. It is not a package variant or reliability grade extension-it is the definitive marker that the 3A60H device has undergone and passed the full AEC-Q101 stress test suite. No other version of 3A60 carries this qualification.
Can the 3A60H replace non-AEC-Q101 rectifiers like 1N5408 in automotive designs?
No-the 3A60H should not be treated as a drop-in replacement for generic rectifiers such as 1N5408 in automotive applications unless the full AEC-Q101 validation scope (including HTOL, TC, and HAST) is required. While both are DO-15 3A/1000V devices, only the 3A60H meets automotive reliability standards; substituting without requalification risks field failure.
What is the maximum junction temperature and thermal resistance of the 3A60H?
The 3A60H has a maximum junction temperature (TJ) of +150°C and a junction-to-lead thermal resistance (RθJL) of 17°C/W. These values are measured under standard test conditions and enable direct thermal coupling to PCB copper or chassis mounts. Its RθJA is 52°C/W, confirming suitability for natural-convection cooling in compact enclosures.
How is polarity identified on the 3A60H package?
Polarity on the 3A60H is indicated by a visible cathode band located near one lead end of the DO-204AC (DO-15) package. The banded end is the cathode; the opposite (unbanded) end is the anode. This marking complies with JEDEC standards and is verified in the Package Outline Dimensions and Marking Diagram sections of the 3A60H datasheet.
