Product details
Overview
SMCJ60CA from Taiwan Semiconductor is a bidirectional 1500W transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 60V working stand-off voltage (VWM), 66.7–73.7V breakdown voltage (VBR), and 96.8V maximum clamping voltage (VC) at 16A peak pulse current - designed for automotive load-dump and ISO 7637-2 Pulse 1/2a/2b/3a/3b protection in power supply rails and CAN/LIN interfaces.
For engineers reviewing the SMCJ60CA datasheet, SMCJ60CA pinout, SMCJ60CA application, or SMCJ60CA equivalent, this device is selected for high-energy ESD and electrical fast transient (EFT) immunity in industrial control I/O, automotive body electronics, DC-DC converter input stages, and telecom power entry circuits where sub-1ps response time and <1µA leakage above 10V are critical.
Technical Context
The SMCJ60CA employs a glass-passivated silicon junction optimized for bidirectional surge suppression, meeting ISO 7637-2 test requirements across all defined pulses without external polarity management. Its unidirectional counterpart (SMCJ60A) shares identical VWM, VBR, and VC specs but lacks reverse-direction conduction capability.
Thermal performance is defined by RθJA = 55°C/W and RθJC = 10°C/W, enabling reliable operation up to TJ = +150°C. The device sustains 200A non-repetitive forward surge (IFSM) and delivers 1500W peak pulse power (PPK) under 1ms 10/1000µs waveform per Fig.5.
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 @ IT = 1 mA - Confirmed breakdown threshold range ensuring predictable turn-on during transients |
| VC @ IPPM | 96.8 V @ 16 A - Clamped voltage seen by protected circuit during worst-case 1500W surge |
| PPK | 1500 W - Peak pulse power handling per 1ms 10/1000µs waveform, derated above 25°C ambient |
| IR @ VWM | <1 µA - Reverse leakage at rated stand-off, minimizing standby power loss in battery-backed systems |
| TJ max | +150 °C - Maximum junction temperature supporting under-hood automotive deployment |
| Package | DO-214AB (SMC) - Surface-mount outline with 0.210g mass, UL 94V-0 molding, and JESD201 Class 2 whisker resistance |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with coplanar matte tin-plated leads; cathode band marking denotes polarity for unidirectional variants only - SMCJ60CA is bidirectional and symmetric, with both terminals electrically identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | Either terminal serves as clamping node; no polarity dependency enables simplified PCB layout in AC-coupled or floating bus lines |
| Case | Non-electrical mechanical interface | No internal thermal or electrical connection to die; heatsinking requires direct pad-to-copper contact beneath center tab |
Key Features
| Feature | Design Value |
|---|---|
| ISO 7637-2 compliance | Validated for Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect/load dump), and Pulse 3a/3b (EFT), eliminating need for additional filtering in automotive ECUs |
| Sub-1ps response time | Typically <1.0 ps from 0 V to VBR min - ensures clamping activation before transient energy couples into downstream ICs |
| Moisture sensitivity level 1 | Unlimited floor life at ≤30°C/60% RH - supports standard SMT assembly without dry-pack or baking requirements |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets RoHS and automotive OEM material declarations for flame-retardant PCB assemblies |
| 1500W peak power rating | Sustains 16A peak impulse current (IPPM) at 96.8V clamping - protects 12V/24V systems against 100V load-dump events per ISO 16750-2 |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from battery line transients during ignition cycling and alternator load dump.

IC Role / Device Role / Timing Role: TVS placed across input bulk capacitor terminals, clamping transients before they propagate to controller IC (e.g., LM5116) and gate drivers. Use Value: Eliminates need for oversized input capacitance or redundant overvoltage lockout, preserving efficiency and enabling compact 12V→3.3V designs for edge AI modules. |
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 (Bourns) | Same DO-214AA (SMB) package, lower PPK = 600W, VC = 96.8V @ 6.5A | Lower surge capacity limits use to sub-100V transients; unsuitable for ISO 7637-2 Pulse 2b load dump | Select only when space-constrained layouts require SMB footprint and energy threats are limited to IEC 61000-4-2/4-4 |
| 1.5KE60CA (ON Semiconductor) | Through-hole DO-201AD package, PPK = 1500W, VC = 96.8V @ 16A, same VWM/VBR | Requires wave soldering or hand assembly; incompatible with fully SMT production lines | Choose only for legacy through-hole designs or prototyping where rework tolerance outweighs automated placement needs |
Compared with SMBJ60CA and 1.5KE60CA, the SMCJ60CA uniquely combines 1500W surface-mount capability, ISO 7637-2 qualification, and DO-214AB thermal performance - making it the preferred choice for automotive-grade SMT power rail protection where board density and regulatory compliance are co-prioritized.

FAQ
What is the clamping voltage of SMCJ60CA at its rated peak pulse current?
The SMCJ60CA has a maximum clamping voltage (VC) of 96.8 V at 16 A peak pulse current (IPPM), measured under the standardized 10/1000 µs waveform per Fig.5 in the datasheet. This value ensures protected circuits experience no more than 96.8 V during a full 1500W transient event, directly supporting design margin calculations for 12V and 24V systems.
Is SMCJ60CA unidirectional or bidirectional, and how does that affect circuit placement?
The SMCJ60CA is a bidirectional TVS diode, meaning it provides symmetrical clamping in both polarities without polarity marking or orientation constraints. Unlike unidirectional SMCJ60A, the CA suffix confirms dual-path conduction - allowing placement across any two nodes (e.g., signal-to-ground or differential lines) without regard to anode/cathode direction, simplifying layout and reducing assembly errors.
Does SMCJ60CA meet automotive transient immunity standards such as ISO 7637-2?
Yes, the SMCJ60CA is explicitly validated to meet ISO 7637-2 for Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect and load dump), and Pulse 3a/3b (EFT), as stated in the FEATURES section of the datasheet. Its 1500W rating and 96.8V clamping enable compliance with Pulse 2b's 100V/10Ω requirement in 12V systems without additional components.
What is the maximum junction temperature and thermal resistance of SMCJ60CA?
The SMCJ60CA has a maximum junction temperature (TJ) of +150°C and thermal resistances of RθJA = 55°C/W (junction-to-ambient) and RθJC = 10°C/W (junction-to-case). These values are measured under standard JEDEC conditions and confirm suitability for under-hood automotive environments and thermally dense industrial PCBs when mounted on ≥1 sq-in copper pour.
How does the leakage current of SMCJ60CA impact low-power battery-operated designs?
The SMCJ60CA exhibits maximum reverse leakage current (IR) of <1 µA at its 60V working stand-off voltage (VWM), measured at 25°C. This ultra-low leakage ensures negligible drain on 12V/24V battery systems - critical for always-on automotive modules (e.g., telematics, alarm controllers) where annual self-discharge must remain below 10mAh to avoid parasitic battery depletion.
