Product details
Overview
SMBJ60CA-13-F from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in SMB package, designed for robust overvoltage protection in DC power lines and signal interfaces. It features 60 V reverse standoff voltage (VRWM), 66.7–76.7 V breakdown voltage (VBR), 96.8 V max clamping voltage (VC) at 6.2 A peak pulse current, and 600 W peak pulse power dissipation per 10/1000 µs waveform - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the SMBJ60CA-13-F datasheet, SMBJ60CA-13-F pinout, SMBJ60CA-13-F application, or SMBJ60CA-13-F equivalent, key selection criteria include clamping performance under 8.3 ms surge, bi-directional symmetry for AC-coupled or floating bus protection, thermal derating above +25°C, and RoHS-compliant matte tin termination compatibility with lead-free reflow profiles.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds VRWM (60 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated die ensures stable VBR tolerance and long-term reliability under repetitive stress.
The device is rated for non-repetitive 8.3 ms half-sine surges up to 100 A (IFSM), with thermal derating of 4.8 W/°C above +25°C ambient and steady-state power dissipation of 5.0 W at TL = +75°C - enabling use in thermally constrained PCB layouts with controlled trace width and copper pour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (per 10/1000 µs waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage | 60.0 V (maximum continuous DC or RMS voltage before significant leakage; sets operating margin) |
| Breakdown Voltage | 66.7–76.7 V (VBR range at 1.0 mA IT; confirms avalanche initiation threshold consistency) |
| Clamping Voltage | 96.8 V (max VC at 6.2 A IPP; determines protected circuit's worst-case overvoltage exposure) |
| Peak Pulse Current | 6.2 A (IPP at VC = 96.8 V; quantifies surge current handling under defined clamping condition) |
| Leakage Current | 5.0 µA max @ VRWM (low standby loss; critical for battery-powered or high-impedance sensing nodes) |
| Operating Temp Range | −55°C to +150°C (supports under-hood automotive and industrial environments without derating) |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case per UL 94V-0, 0.1 g mass, moisture sensitivity level 1. Terminals are matte tin-plated for lead-free solderability per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Bi-directional terminals | No polarity marking; symmetric I-V curve enables AC line or differential pair protection without orientation constraints |
| Cathode Band | N/A (bi-directional) | Not present - distinguishes SMBJ60CA from unidirectional SMBJ60A; eliminates assembly error risk in bidirectional applications |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables protection against IEC 61000-4-5 Level 4 (4 kV surge) on 12–48 V DC rails with margin |
| Glass passivated die | Ensures <±5% VBR drift after 1000x surge cycles; critical for long-life industrial deployments |
| Bi-directional configuration | Supports protection of RS-485, CAN FD, or Ethernet PHY lines without external series components |
| RoHS & halogen-free | Meets IPC-1752A Tier 1 reporting requirements and EU ELV Directive for automotive supply chains |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protects 24 V digital input channels against induced lightning surges and relay coil flyback in factory automation cabinets. IC Role / Device Role / Timing Role: Shunt TVS placed between channel and ground, triggered within <1 ns to clamp transients below 100 V. Use Value: Prevents microcontroller GPIO latch-up and extends mean time between failures (MTBF) by >5× versus Zener-only solutions. | Use Scenario: Safeguards LIN bus transceivers and door module sensors from load dump and jump-start events in 12 V vehicle networks. IC Role / Device Role / Timing Role: Bi-directional clamping element across LIN data line and ground, absorbing ±100 V/50 ms pulses per ISO 7637-2 Pulse 5a. Use Value: Maintains bus communication integrity during cold-crank conditions where system voltage dips to 6 V then spikes to 35 V. |
| DC Power Supply Input Stage | RS-485 Transceiver Interface |
Use Scenario: Installed at front-end of 48 V telecom power supply to suppress EFT bursts and capacitive coupling from adjacent AC mains traces. IC Role / Device Role / Timing Role: First-line defense parallel to bulk capacitor, activated before upstream fuse opens during 1 kV/50 Ω surge. Use Value: Reduces required input capacitor derating by 20%, lowering BOM cost while meeting EN 61000-4-4 Level 4 immunity. | Use Scenario: Mounted directly at RS-485 connector pins to protect half-duplex transceivers (e.g., MAX13487) from cable discharge events. IC Role / Device Role / Timing Role: Symmetric clamping device across A/B differential pair and ground, limiting common-mode transients to <100 V. Use Value: Eliminates need for discrete resistor-capacitor snubbers, reducing PCB area by 35% and improving EMC radiated emissions margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-13-F | Unidirectional; cathode-marked; 5.0 µA IR @ VRWM vs. same for SMBJ60CA | Requires correct polarity placement; unsuitable for AC-coupled or floating differential buses | Select only when protecting grounded DC rails with known polarity (e.g., +12 V to GND). |
| SMCJ60CA | Same electrical specs but SMC package (larger footprint, 1.5 g mass, 1500 W PPK) | Higher thermal mass supports repeated surges; requires 30% more PCB area | Choose when surge repetition rate exceeds 1 pulse/minute or ambient exceeds +105°C. |
Compared with SMBJ60A-13-F, SMBJ60CA-13-F enables polarity-agnostic layout and AC line protection; versus SMCJ60CA, it trades peak power headroom for space-constrained designs where 600 W suffices and board real estate is premium.

FAQ
What is the difference between SMBJ60CA-13-F and SMBJ60A-13-F?
SMBJ60CA-13-F is bi-directional with symmetric clamping for AC or floating circuits, while SMBJ60A-13-F is unidirectional with a cathode band and only clamps positive transients relative to its marked cathode. Both share identical VRWM (60 V), VBR (66.7–76.7 V), and VC (96.8 V), but SMBJ60A cannot protect negative-going surges without additional components.
Does SMBJ60CA-13-F meet AEC-Q200 for automotive use?
No - SMBJ60CA-13-F is not AEC-Q200 qualified. Diodes offers the automotive-grade P6SMBJ60CA variant (with extended temperature screening and PPAP documentation) for qualified automotive applications. This commercial-grade part is suitable for non-safety-critical automotive subsystems where qualification is not mandated.
What is the recommended PCB pad layout for SMBJ60CA-13-F?
Use the SMB outline per Diodes' package drawing: 5.00–5.59 mm length (E), 3.30–3.94 mm width (A), 1.96–2.21 mm height (C). Thermal pads should connect both terminals to ≥1 cm² internal copper planes via ≥4 thermal vias (0.3 mm diameter) to improve surge heat dissipation and reduce clamping voltage overshoot during fast transients.
Can SMBJ60CA-13-F be used in parallel for higher surge current handling?
No - paralleling TVS diodes causes current imbalance due to VBR tolerance (±7.5%) and thermal runaway risk. For >6.2 A IPP, select a single higher-power device like SMCJ60CA (1500 W) or SMAJ60CA (400 W), or implement staged protection with upstream MOV + downstream TVS for coordinated clamping.
