Product details
Overview
SMCJ60AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 µs waveform. It clamps transients to ≤96.8 V at 15.5 A peak current and operates from –55 °C to +150 °C, targeting automotive power rail and industrial sensor interface protection.
For engineers reviewing the SMCJ60AHE3_A/I datasheet, SMCJ60AHE3_A/I pinout, SMCJ60AHE3_A/I application, or SMCJ60AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.45), 1.0 µA max reverse leakage at VWM, MSL Level 1 rating, and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages and low incremental surge resistance. Its unidirectional polarity features a cathode band marking and supports single-polarity DC line protection without AC coupling constraints.
The device is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and exhibits a positive temperature coefficient of VBR (+0.105 %/°C), enabling stable breakdown behavior across its –55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected lines. |
| VBR min/max | 66.7 V / 73.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold under surge conditions. |
| VC @ IPPM | 96.8 V - Clamped voltage at 15.5 A peak pulse current; determines maximum stress imposed on downstream circuitry during surge. |
| PPPM | 1500 W - Peak pulse power handling capability with 10/1000 µs waveform; quantifies energy absorption capacity per transient event. |
| ID @ VWM | 1.0 µA - Reverse leakage at rated standoff voltage; critical for low-power sensor or battery-backed circuits where standby current matters. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive or high-ambient industrial environments. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal footprint; supports automated placement and reflow soldering. |
Pinout & Package
SMCJ60AHE3_A/I is housed in an SMC (DO-214AB) package with two terminals: anode and cathode. The cathode is marked by a visible band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink | Connected to ground or low-impedance return path; carries full transient current during clamping operation. |
| Anode | Protected line connection | Connected to the signal or power line requiring protection; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies, meeting stress testing requirements for temperature cycling, humidity, and mechanical shock. |
| MSL Level 1 | Rated for unlimited floor life at ≤30 °C/85 % RH, eliminating bake-out requirements prior to reflow assembly. |
| Low clamping ratio (VC/VBR) | ≈1.45 - Minimizes overvoltage overshoot during clamping, reducing risk of damage to sensitive downstream ICs like microcontrollers or CAN transceivers. |
| Glass passivated junction | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives, critical for harsh-environment deployments. |
| 1500 W peak pulse rating | Withstands ISO 7637-2 Pulse 1, 2a, 3a/b, and IEC 61000-4-5 Level 4 surges without degradation when mounted per recommended pad layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60AHE3_A/I | Lower PPPM (400 W), same VWM/VBR, SMA package (smaller thermal mass). | Not suitable for ISO 7637-2 Pulse 5a load dump; limited to lower-energy transients like ESD or contact discharge. | Select only when space-constrained and surge energy is confirmed ≤400 W. |
| SMCJ60CAHE3_A/I | Bidirectional variant; identical VWM/VBR/PPPM but symmetrical clamping in both polarities. | Required for AC-coupled or floating signal lines (e.g., RS-485, CAN FD); unsuitable for DC-biased rails with defined polarity. | Choose when protecting bidirectional interfaces or where polarity reversal risk exists. |
Compared with SMAJ60AHE3_A/I and SMCJ60CAHE3_A/I, the SMCJ60AHE3_A/I delivers higher surge energy handling in a thermally robust SMC package while maintaining unidirectional polarity-making it optimal for automotive and industrial DC power rail protection where peak pulse power and AEC-Q101 compliance are mandatory.

FAQ
What is the clamping voltage of SMCJ60AHE3_A/I at its rated peak pulse current?
The SMCJ60AHE3_A/I has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current (IPPM) of 15.5 A using a 10/1000 µs waveform. This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC guidelines and represents the upper limit of voltage seen by protected circuitry during worst-case surge events.
Is SMCJ60AHE3_A/I qualified for automotive applications?
Yes, SMCJ60AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix in its ordering code. This certification confirms that the device has passed rigorous stress tests-including temperature cycling, humidity bias, mechanical shock, and high-temperature reverse bias-required for use in automotive powertrain, chassis, and body electronics systems.
What does the "_A/I" suffix mean in SMCJ60AHE3_A/I?
The "_A/I" suffix in SMCJ60AHE3_A/I denotes the revision level ("A") and packaging format ("I" = 13-inch diameter plastic tape and reel, 3500 units per reel). This matches Vishay's standard ordering nomenclature shown in the datasheet's Ordering Information table and confirms full compliance with RoHS and AEC-Q101 requirements.
How does the thermal resistance of SMCJ60AHE3_A/I affect its power derating?
SMCJ60AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W. When ambient temperature exceeds 25 °C, its power dissipation must be linearly derated-e.g., at 75 °C ambient, maximum continuous power drops to approximately 3.25 W (6.5 W × [1 − (75−25)/150]). Derating curves are provided in Figure 2 of the Vishay datasheet 88394.
Can SMCJ60AHE3_A/I be used in bidirectional signal protection?
No, SMCJ60AHE3_A/I is a unidirectional TVS diode and must not be used for bidirectional signal lines unless paired with a second device in anti-series configuration. For native bidirectional protection, select the SMCJ60CAHE3_A/I variant, which provides symmetrical clamping in both polarities and shares identical VWM, VBR, and PPPM ratings.
