Product details
Overview
SMCJ60CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 60 V standoff voltage (VWM), 96.8 V maximum clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the SMCJ60CAHE3/57T datasheet, SMCJ60CAHE3/57T pinout, SMCJ60CAHE3/57T application, or SMCJ60CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical bidirectional conduction enabling suppression of both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C peak.
The thermal design relies on low RθJL (15 °C/W) and moderate RθJA (75 °C/W), requiring PCB copper pad area per datasheet recommendation (0.31" × 0.31") to sustain 1500 W surge pulses. It meets UL 497B recognition and complies with ANSI/IEEE C62.35 surge test standards.

Pinout & Package
SMCJ60CAHE3/57T uses the SMC (DO-214AB) package: a two-terminal, non-polarized surface-mount case with matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no cathode marking; terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Provides low-impedance path for negative-going surges when referenced to system ground |
| Cathode | Transient return path (bidirectional) | Provides low-impedance path for positive-going surges; electrically identical to Anode in CA devices |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS subsystems |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio TVS devices |
| MSL Level 1 rating | Permits standard SMT reflow without baking, reducing manufacturing overhead |
| UL 497B recognition | Confirms compliance for telecom and industrial surge protection applications per safety standard |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/61 | Lower PPPM (400 W), smaller SMA package, same VWM/VC specs | Not suitable for high-energy automotive load dump; limited to consumer-grade signal line protection | Select when board space is constrained and surge energy is ≤400 W |
| 1.5KE60CA | Through-hole DO-201 package, identical electrical specs but higher RθJA (100 °C/W) | Requires larger PCB real estate and manual or wave-solder process; not AEC-Q101 qualified | Select only for legacy through-hole designs where rework to SMT is impractical |
Compared with SMAJ60CA-E3/61 and 1.5KE60CA, the SMCJ60CAHE3/57T delivers 3.75× higher surge power handling in an AEC-Q101-qualified SMT package, enabling robust protection in space-constrained automotive and industrial PCBs without thermal derating penalties.

FAQ
What is the standoff voltage rating of the SMCJ60CAHE3/57T?
The SMCJ60CAHE3/57T has a standoff voltage (VWM) of 60 V, meaning it remains non-conductive under normal operating conditions up to this reverse voltage. This value is confirmed in the Vishay datasheet Document Number 88394, Table on page 2, and defines the maximum continuous DC or RMS voltage the device can block before entering avalanche breakdown.
Is the SMCJ60CAHE3/57T suitable for automotive applications?
Yes, the SMCJ60CAHE3/57T is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 09-Jan-2024. Its construction includes glass-passivated junctions, MSL Level 1 rating, and operation up to +150 °C junction temperature - all validated for automotive powertrain, body electronics, and ADAS subsystems.
What does the "CA" suffix indicate in SMCJ60CAHE3/57T?
The "CA" suffix denotes a bidirectional configuration: the SMCJ60CAHE3/57T provides symmetrical clamping for both positive and negative transients, with identical electrical characteristics in either direction. This eliminates polarity concerns during placement and enables use on AC-coupled or floating nodes, unlike unidirectional "A" variants.
What is the maximum clamping voltage of the SMCJ60CAHE3/57T at rated surge current?
The SMCJ60CAHE3/57T clamps to a maximum of 96.8 V when subjected to its rated 15.5 A peak pulse current (IPPM) with a 10/1000 μs waveform. This VC value is measured per ANSI/IEEE C62.35 and ensures downstream components see controlled overvoltage during surge events.
Does the SMCJ60CAHE3/57T require a heatsink for standard operation?
No external heatsink is required for transient suppression duty, as the SMCJ60CAHE3/57T is rated for 6.5 W steady-state power dissipation on an infinite heatsink at TA = 50 °C. In typical surge applications, energy is absorbed capacitively and dissipated thermally over milliseconds - PCB copper pads (0.31" × 0.31" per terminal) provide sufficient thermal mass per Vishay's recommended layout.
