Product details
Overview
SMCJ60CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 60 V standoff voltage (VWM), 96.8 V maximum clamping voltage at 15.5 A peak pulse current, and 1500 W peak pulse power rating for 10/1000 µs waveform. It protects sensitive ICs, MOSFETs, and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial power electronics.
For engineers reviewing the SMCJ60CAHM3/I datasheet, SMCJ60CAHM3/I pinout, SMCJ60CAHM3/I application, or SMCJ60CAHM3/I equivalent, this device is selected for high-energy surge immunity in DC power rails, bidirectional data line protection, and AEC-Q101-compliant automotive subsystems requiring halogen-free, RoHS-compliant components with MSL Level 1 reliability.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical breakdown (VBR min/max = 66.7 V / 73.7 V at 1 mA), clamping (VC = 96.8 V at IPPM), and leakage (ID ≤ 1.0 µA at VWM = 60 V) characteristics in either direction. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance under repetitive transient stress.
Designed for surface-mount automation, the SMCJ60CAHM3/I uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 2 whisker resistance. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - validated for automotive-grade temperature cycling (-55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 48 V systems. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed bidirectional breakdown range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 96.8 V at 15.5 A - Clamped voltage during 10/1000 µs surge; limits downstream voltage stress to <97 V under full-rated energy. |

Pinout & Package
SMCJ60CAHM3/I is housed in an SMC (DO-214AB) surface-mount package with two terminals: no polarity marking for bidirectional operation. Leads are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (positive half-cycle) | Accepts surge current during positive voltage excursions; forms symmetrical conduction path with cathode. |
| Cathode | Transient current entry point (negative half-cycle) | Accepts surge current during negative voltage excursions; completes bidirectional clamping loop with anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM performance in both directions - eliminates need for polarity-aware placement in AC-coupled or floating signal paths. |
| 1500 W peak pulse power | Withstands 10/1000 µs surges up to 15.5 A - exceeds IEC 61000-4-5 Level 4 requirements for industrial and automotive applications. |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock - supports Tier-1 BOM inclusion without requalification. |
| Halogen-free & RoHS | HM3 suffix confirms compliance with JEDEC JS709E and EU RoHS Directive 2011/65/EU - satisfies global environmental procurement mandates. |
| MSL Level 1 | No floor life limitation; compatible with standard reflow profiles up to 260 °C peak - simplifies SMT manufacturing and avoids moisture sensitivity handling. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Use Value: Absorbs 1500 W surge energy without degradation, enabling compliance with GR-1089-CORE and ITU-T K.20/21 standards. | Use Scenario: Shielding microcontroller I/O and gate driver circuits in solar string inverters exposed to grid-switching transients and PV array fault currents. IC Role / Device Role / Timing Role: Secondary-stage clamping device on isolated 3.3 V/5 V control rails downstream of isolated DC-DC converters. Use Value: Operates reliably from -40 °C to +125 °C ambient with no parameter drift, supporting long-term field deployment in outdoor enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC50-60CA | Lower PPPM (500 W), same VWM (60 V), smaller SMA package (DO-214AC) | Not rated for AEC-Q101; limited to commercial-grade consumer/industrial use | Select when space-constrained layouts require smaller footprint and surge energy demand is ≤500 W. |
| SMCJ60CAHE3/I | Same electrical specs and SMC package; RoHS-compliant but not halogen-free (E3 vs HM3) | Lacks halogen-free certification; unsuitable for automotive OEMs with strict material declarations | Choose for cost-sensitive industrial designs where halogen-free compliance is not mandated. |
Compared with SAC50-60CA and SMCJ60CAHE3/I, the SMCJ60CAHM3/I uniquely combines 1500 W surge capability, AEC-Q101 qualification, and halogen-free construction - making it the only option qualified for high-reliability automotive power rail protection without trade-offs in energy rating or environmental compliance.

FAQ
What does the 'CA' suffix indicate in SMCJ60CAHM3/I?
The 'CA' suffix in SMCJ60CAHM3/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression in both forward and reverse directions. This eliminates polarity concerns during PCB placement and enables use on AC-coupled lines, floating grounds, or differential buses where voltage polarity may reverse. Unlike unidirectional variants (e.g., SMCJ60A), SMCJ60CAHM3/I has no cathode band marking.
Is SMCJ60CAHM3/I suitable for automotive applications?
Yes, SMCJ60CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - meeting stringent automotive reliability and environmental requirements. It operates across -55 °C to +150 °C junction temperature and is validated for thermal cycling, humidity bias, and mechanical shock, making it appropriate for engine control units, ADAS modules, and body electronics.
What is the clamping voltage of SMCJ60CAHM3/I at its rated peak pulse current?
The clamping voltage (VC) of SMCJ60CAHM3/I is 96.8 V at its rated peak pulse current (IPPM) of 15.5 A, measured using the standard 10/1000 µs double-exponential waveform. This value represents the maximum voltage seen by downstream circuitry during a full-rated surge event and is critical for ensuring protected components remain within their absolute maximum ratings.
How does the HM3 suffix differ from E3 or HE3 in Vishay's SMCJ series?
The HM3 suffix in SMCJ60CAHM3/I specifies halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. In contrast, E3 indicates RoHS-compliant commercial grade only, while HE3 adds AEC-Q101 qualification but retains standard brominated flame retardants. HM3 meets stricter material declarations required by Tier-1 automotive suppliers and aligns with JEDEC JS709E halogen-free definitions.
Can SMCJ60CAHM3/I be used in place of a unidirectional TVS like SMCJ60AHM3/I?
No - SMCJ60CAHM3/I is bidirectional and lacks polarity marking, whereas SMCJ60AHM3/I is unidirectional with a cathode band. Substituting them requires verifying circuit topology: SMCJ60CAHM3/I is appropriate for AC or floating rails, but will not provide correct forward conduction behavior in DC-biased unidirectional paths. Always confirm schematic polarity and clamping direction before replacement.
