Product details
Overview
SMBJ60CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 60 V standoff voltage (VWM), 66.7–73.7 V breakdown range (VBR at 1 mA), 96.8 V maximum clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the SMBJ60CA-E3/5B datasheet, SMBJ60CA-E3/5B pinout, SMBJ60CA-E3/5B application, or SMBJ60CA-E3/5B equivalent, this part delivers verified bidirectional surge suppression with MSL Level 1 moisture sensitivity, RoHS-compliant matte tin terminations, and AEC-Q101 qualification availability - critical for automotive body electronics, industrial PLC inputs, and telecom line protection where polarity-agnostic transient immunity is required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast sub-nanosecond response to transients exceeding 1 kV/µs.
Thermal performance is defined by RθJA = 100 °C/W (on 0.2" × 0.2" copper pads) and RθJL = 20 °C/W, supporting reliable operation up to TJ = +150 °C. The device meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge test standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for safe DC bias in protected circuit. |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 96.8 V at 6.2 A - Clamped voltage under 10/1000 µs surge; defines worst-case stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability; supports repetitive 0.01% duty cycle surges per JEDEC standards. |
| IPPM | 6.2 A - Peak surge current corresponding to VC; directly determines PCB trace sizing and fuse coordination. |

Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals function as anode and cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal conducts when reverse-biased relative to the other; no fixed polarity - enables AC line or floating node protection. |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completing symmetrical conduction path; identical electrical behavior to Terminal 1. |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) when properly mounted on recommended 5.0 mm × 5.0 mm copper pads. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without prebaking; eliminates moisture-related popcorning risk in SMT assembly. |
| UL 497B recognized (QVGQ2) | Validated for telecom and industrial signal-line protection per safety standard - reduces certification burden in end equipment. |
| RoHS-compliant matte tin plating | Ensures solderability per J-STD-002 and whisker resistance per JESD 201 Class 2 - critical for long-life industrial deployments. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to 24 V supply switching noise and relay coil flyback. IC Role / Device Role / Timing Role: Bidirectional TVS placed between signal line and ground to clamp ±1 kV transients before reaching ADC input or op-amp buffer. Use Value: Prevents sensor signal corruption and microcontroller reset events caused by >100 V spikes induced by nearby solenoid actuation. |
Use Scenario: Safeguarding LIN bus transceiver I/O pins against load dump and jump-start induced surges in door module ECUs. IC Role / Device Role / Timing Role: Standoff-rated TVS shunting transient energy directly at connector entry point, upstream of transceiver ESD diodes. Use Value: Maintains LIN communication integrity during 12 V system faults by limiting bus voltage to <100 V for <100 ns - within transceiver absolute max rating. |
| Telecom Line Card Protection | PLC Digital Input Stage |
|
Use Scenario: Shielding RS-485 transceiver terminals from lightning-induced surges on outdoor data links. IC Role / Device Role / Timing Role: Bidirectional TVS connected across differential pair (A–B) and to ground, providing common-mode and differential-mode clamping. Use Value: Limits differential voltage excursion to ≤96.8 V during 10/1000 µs surges - preserving transceiver isolation barrier and preventing latch-up. |
Use Scenario: Securing 24 V DC digital input channels in programmable logic controllers against field wiring misconnections and inductive load kickback. IC Role / Device Role / Timing Role: TVS placed between input terminal and chassis ground, absorbing >600 W surge energy before reaching optocoupler input LED. Use Value: Extends input stage MTBF by eliminating optocoupler forward-voltage overstress and LED degradation from repeated 500 V transients. |
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-M3/5B | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package; same thermal and surge ratings. | No functional difference; selected when halogen-free compliance is mandated by OEM environmental policy. | Direct drop-in replacement where halogen-free materials are required; no layout or validation changes needed. |
| SMCJ60CA-E3/2A | Same VWM/VC specs but in larger SMC (DO-214AB) package; higher PPPM = 1500 W and IPPM = 15.4 A due to improved thermal mass. | Used where higher surge margin is needed (e.g., primary-side AC input protection), but requires larger PCB area and different pad layout. | Select when system-level surge testing exceeds 600 W requirements; not pin-compatible - redesign required. |
Compared with SMBJ60CA-E3/5B, the M3/5B variant offers identical protection performance with halogen-free construction, while the SMCJ60CA-E3/2A provides 2.5× higher surge capacity at the cost of footprint and layout compatibility - making SMBJ60CA-E3/5B optimal for space-constrained 600 W-class protection.

FAQ
What is the standoff voltage rating of SMBJ60CA-E3/5B?
The SMBJ60CA-E3/5B has a maximum reverse standoff voltage (VWM) of 60 V, meaning it remains non-conductive up to this DC or RMS voltage level while maintaining reverse leakage below 1 µA. This rating ensures compatibility with 48 V industrial systems and 24 V automotive domains where sustained overvoltage must be avoided before clamping initiates.
Is SMBJ60CA-E3/5B suitable for automotive applications?
Yes - while the base SMBJ60CA-E3/5B is commercial-grade, Vishay offers AEC-Q101 qualified variants (e.g., SMBJ60CAHE3_B/I) with identical electrical specs. The SMBJ60CA-E3/5B itself shares the same die, package, and thermal design; only the test screening differs. For non-safety-critical body electronics, SMBJ60CA-E3/5B is widely deployed with customer qualification.
How does SMBJ60CA-E3/5B differ from unidirectional SMBJ60A-E3/5B?
The SMBJ60CA-E3/5B is bidirectional with symmetrical VBR and clamping in both polarities, whereas SMBJ60A-E3/5B is unidirectional and conducts only when cathode is positive relative to anode. The "CA" suffix explicitly denotes bidirectional functionality - critical for protecting AC signals, differential pairs, or floating nodes where polarity reversal occurs.
What is the clamping voltage of SMBJ60CA-E3/5B under surge conditions?
The SMBJ60CA-E3/5B clamps to a maximum of 96.8 V when subjected to its rated 6.2 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is measured at the device terminals and represents the worst-case voltage imposed on protected circuitry during a surge event - a key parameter for verifying downstream IC survivability.
Does SMBJ60CA-E3/5B require special PCB layout considerations?
Yes - to achieve rated 600 W pulse power, Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Narrow traces or insufficient copper reduce heat dissipation, lowering actual surge capability. Thermal vias under pads and ground-plane connection are recommended for high-reliability designs, especially above 85 °C ambient.
