Product details
Overview
SA60CAH from Taiwan Semiconductor is a bidirectional AEC-Q101-qualified transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, designed for automotive and industrial surge protection. It features 60 V working stand-off voltage (VWM), 66.7–81.5 V breakdown voltage (VBR @ 1 mA), 500 W peak pulse power (10/1000 µs), clamping voltage of 107 V at 4.9 A IPPM, and operating junction temperature up to +175 °C.
For engineers reviewing the SA60CAH datasheet, SA60CAH pinout, SA60CAH application, or SA60CAH equivalent, this device is selected for high-reliability ESD and electrical fast transient (EFT) protection in automotive body electronics, powertrain sensors, and 12 V/24 V DC systems where AEC-Q101 compliance and low clamping ratio are critical.
Technical Context
The SA60CAH is a bidirectional TVS diode with symmetrical avalanche breakdown characteristics in both polarities, enabling robust protection against reverse- and forward-polarity transients without polarity sensitivity. Its 10/1000 µs waveform-rated 500 W surge capability and sub-nanosecond response time (<5 ns) ensure effective suppression of ISO 7637-2 and IEC 61000-4-4 compliant surges.
It operates across –55 °C to +175 °C junction temperature range and maintains <1 µA reverse leakage at 60 V (VWM), supporting stable standby performance in always-on automotive modules. The device uses silicon planar construction with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous DC or RMS voltage the device blocks without clamping; sets system operating voltage ceiling. |
| VBR min/max | 66.7 V / 81.5 V @ 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on before downstream IC damage. |
| VC @ IPPM | 107 V @ 4.9 A - Clamping voltage under full 500 W surge; defines worst-case voltage seen by protected circuitry. |
| PPK | 500 W - Peak pulse power handling per 10/1000 µs waveform; meets ISO 7637-2 Pulse 5a/b severity levels. |
| TJ max | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| IR @ VWM | <1 µA - Reverse leakage current at rated stand-off voltage; minimizes quiescent power loss in battery-critical systems. |

Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking omitted (bidirectional symmetry). Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Polarity is non-applicable; terminals are electrically identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge conduction path | Either terminal serves as input/output; no polarity dependency simplifies PCB layout and eliminates orientation errors. |
| Lead 1 / Lead 2 | Transient energy dissipation interface | Direct connection to protected line and ground; low-inductance path required to maintain clamping speed <5 ns. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
| 500 W 10/1000 µs surge rating | Withstands repetitive load dump and inductive switching events in 12 V/24 V vehicle electrical systems. |
| <5 ns response time (bidirectional) | Ensures clamping activation before transient energy couples into sensitive analog or digital inputs. |
| RoHS & halogen-free (IEC 61249-2-21) | Complies with automotive environmental regulations and supports lead-free reflow and wave soldering processes. |
| DO-204AC mechanical robustness | UL 94V-0 molding compound and 0.375" lead length thermal derating support high-power dissipation in constrained spaces. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA | Same VWM (60 V), but SMB package (surface-mount); lower PPK (600 W), higher VC (103 V @ 5.8 A). | Requires PCB redesign for SMT placement; better suited for space-constrained board-level protection vs. cable-entry points. | Select SMBJ60CA when automated assembly and footprint reduction outweigh axial lead serviceability needs. |
| P6KE60CA | Same DO-15 package and bidirectional function; lower PPK (600 W), higher VC (107 V @ 5.6 A), no AEC-Q101 qualification. | Lacks automotive qualification; suitable for industrial/commercial systems where extended temperature validation is not required. | Choose P6KE60CA for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMBJ60CA and P6KE60CA, the SA60CAH uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and guaranteed 500 W surge rating with ≤107 V clamping-making it the preferred choice for production automotive modules requiring traceable reliability and legacy assembly support.

FAQ
What is the clamping voltage of SA60CAH under full-rated surge current?
The SA60CAH has a maximum clamping voltage (VC) of 107 V at 4.9 A peak pulse current (IPPM), measured per 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 500 W transient event and is confirmed in the official TSC SA Series datasheet revision L2105, Table on page 4.
Is SA60CAH unidirectional or bidirectional?
The SA60CAH is a bidirectional TVS diode, indicated by the "CA" suffix per TSC's ordering nomenclature. Its breakdown and clamping behavior are symmetrical in both polarities, making it suitable for AC-coupled or polarity-agnostic DC protection without orientation constraints.
Does SA60CAH meet AEC-Q101 requirements?
Yes, SA60CAH is explicitly AEC-Q101 qualified, as stated in the "FEATURES" section of the TSC SA Series datasheet (Version L2105). The "H" suffix in the part number denotes AEC-Q101 qualification, covering stress tests including temperature cycling, high-temperature reverse bias, and ESD.
What is the maximum operating temperature for SA60CAH?
The SA60CAH has a maximum junction temperature (TJ) of +175 °C and a storage temperature range of –55 °C to +175 °C. This rating enables deployment in under-hood automotive locations and high-ambient industrial enclosures without thermal derating penalties.
What package type does SA60CAH use?
The SA60CAH uses the DO-204AC (DO-15) axial-leaded package, as confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections of the TSC SA Series datasheet. It features pure tin-plated leads, UL 94V-0 molding compound, and a nominal weight of 0.400 g.
