Product details
Overview
SMCJ60CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), and clamps transients to ≤96.8 V at 15.5 A IPPM - deployed on power rails and signal lines of automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ60CAHE3_A/I datasheet, SMCJ60CAHE3_A/I pinout, SMCJ60CAHE3_A/I application, or SMCJ60CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, 1500 W surge rating with low clamping ratio (VC/VBR ≈ 1.45), and compatibility with automated SMT assembly on 8 mm × 8 mm copper pads.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 60 V; during transient events exceeding VBR, it avalanches symmetrically in both directions to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The device meets MSL Level 1 (260 °C reflow peak) and is qualified to AEC-Q101 for automotive underhood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 66.7 V / 73.7 V at IT = 1 mA - defines precise avalanche onset window for predictable protection threshold |
| VC @ IPPM | 96.8 V at 15.5 A - clamping voltage under 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 1500 W - peak transient energy absorption capability without failure |

| TJ max | +150 °C - enables use in engine control units and industrial power converters with high ambient temps |
| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint |
Pinout & Package
SMCJ60CAHE3_A/I uses the SMC (DO-214AB) package: a 2-terminal, non-polarized surface-mount case with matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no cathode/anode marking; terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Surge Input / Line Side | Connects to unprotected line (e.g., 12 V battery rail or CAN bus); conducts surge current bidirectionally |
| Terminal 2 | Surge Return / Load Side | Connects to protected load (e.g., MCU power input); completes low-impedance path to ground during clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., RS-485, CAN FD) without polarity concerns |
| AEC-Q101 qualification | Validated for automotive underhood environments including thermal cycling, humidity, and mechanical shock per JESD22 standards |
| Low clamping ratio (VC/VBR) | 1.45 - minimizes overvoltage margin between breakdown and clamp, reducing stress on protected MOSFETs and gate drivers |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without popcorn cracking or delamination |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to moisture-induced parameter drift in humid industrial settings |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/57T | Lower PPPM (400 W), same VWM/VBR range, SMA package (smaller footprint, lower thermal mass) | Suitable for space-constrained consumer PCBs but not for automotive load dump where 1500 W is required | Select only when surge energy is ≤400 W and board area is critical; verify thermal derating at 75 °C ambient. |
| SMCJ60CAHM3_A/I | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3) | No functional difference; HM3 used where halogen-free compliance is mandated (e.g., EU WEEE, specific OEM specs) | Direct material substitution when halogen-free requirement applies; same layout, thermal, and reliability behavior. |
Compared with SMCJ60CAHE3_A/I, SMAJ60CA-E3/57T offers reduced surge capacity in a smaller package, while SMCJ60CAHM3_A/I provides identical protection with halogen-free construction - making the HE3 variant optimal for general automotive and industrial use where RoHS suffices.

FAQ
What is the clamping voltage of SMCJ60CAHE3_A/I at its rated peak pulse current?
The SMCJ60CAHE3_A/I clamps to a maximum of 96.8 V when subjected to its rated peak pulse current of 15.5 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads), and represents the upper limit of voltage seen by protected circuitry during worst-case surge events. The SMCJ60CAHE3_A/I achieves this with a clamping ratio of approximately 1.45 relative to its minimum breakdown voltage.
Is SMCJ60CAHE3_A/I suitable for automotive underhood applications?
Yes, the SMCJ60CAHE3_A/I is AEC-Q101 qualified and explicitly rated for automotive underhood use. Its operating junction temperature range of –55 °C to +150 °C, MSL Level 1 reflow compatibility, and validation against mechanical shock, temperature cycling, and humidity testing make it appropriate for engine control units, transmission controllers, and ADAS power supplies. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per Vishay's ordering nomenclature.
How does the bidirectional configuration of SMCJ60CAHE3_A/I affect its placement on a PCB?
The bidirectional configuration of SMCJ60CAHE3_A/I eliminates polarity sensitivity, allowing it to be placed across any two nodes requiring symmetrical overvoltage protection - such as differential data lines (CAN, RS-485) or AC-coupled analog paths. Unlike unidirectional TVS diodes, the SMCJ60CAHE3_A/I has no cathode band marking and functions identically regardless of orientation, simplifying layout and reducing assembly errors in high-volume manufacturing.
What is the maximum leakage current of SMCJ60CAHE3_A/I at its standoff voltage?
The SMCJ60CAHE3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 µA when biased at its 60 V standoff voltage (VWM) and tested at 25 °C. This ultra-low leakage ensures minimal power loss in battery-backed systems and avoids signal distortion in high-impedance sensor interfaces. Leakage remains below 5 µA even at elevated temperatures up to 125 °C, supporting reliable operation in thermally demanding environments.
Can SMCJ60CAHE3_A/I be used in parallel to increase surge handling capacity?
No, SMCJ60CAHE3_A/I should not be paralleled to increase surge rating. Due to inherent VBR tolerances (±5.5% for this part), uneven current sharing will occur during transients, causing one device to absorb most of the energy and potentially fail prematurely. For higher power requirements, select a single TVS with greater PPPM (e.g., 3000 W series) or implement staged protection with upstream MOVs and downstream SMCJ60CAHE3_A/I as a precision clamp.
