Product details
Overview
SMBJ36CA-13-F from Diodes Incorporated is a bi-directional 600W surface-mount transient voltage suppressor (TVS) diode with 36V reverse standoff voltage, 40.0–46.0V breakdown voltage at 1mA, and 58.1V maximum clamping voltage at 10.3A peak pulse current. It features glass-passivated die construction, UL 94V-0 molded plastic SMB package, and is designed for overvoltage protection in DC power rails and I/O interfaces of industrial control systems.
For engineers reviewing the SMBJ36CA-13-F datasheet, SMBJ36CA-13-F pinout, SMBJ36CA-13-F application, or SMBJ36CA-13-F equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak pulse current capability under 8.3ms surge, bi-directional symmetry for AC-coupled lines, and RoHS-compliant matte tin lead finish for lead-free reflow compatibility.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection of AC signal paths and ungrounded data lines without polarity constraints. Its glass-passivated junction ensures stable leakage (<5µA at 36V) and repeatable breakdown behavior over temperature (-55°C to +150°C).
The device responds to transients with sub-nanosecond turn-on time, clamping surges up to 600W (8.3ms half-sine) while limiting voltage to ≤58.1V. Thermal derating follows 4.8W/°C above +25°C ambient, with steady-state dissipation rated at 5.0W at +75°C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 8.3ms surge events per REA 10×1000 waveform without failure |
| Reverse Standoff Voltage | 36V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 40.0–46.0V @ 1mA - precise VBR window ensures reliable triggering above normal operating voltage |
| Clamping Voltage | 58.1V @ 10.3A - limits transient voltage seen by downstream circuitry during worst-case surge |
| Leakage Current | ≤5.0µA @ 36V - negligible standby power loss and no interference with high-impedance sensing nodes |
| Package | SMB - standardized surface-mount outline (5.00–5.59mm length, 3.30–3.94mm width) compatible with automated placement |
| Operating Temperature | -55°C to +150°C - validated for under-hood automotive, industrial motor drives, and outdoor power electronics |
Pinout & Package
Two-terminal SMB package: anode and cathode terminals are symmetrical for bi-directional operation; no polarity marking required. Case is molded plastic (UL 94V-0), weight ≈0.1g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (positive polarity) | Conducts surge current into device during positive overvoltage event; tied to protected line |
| Cathode | Transient current entry point (negative polarity) | Conducts surge current into device during negative overvoltage event; tied to protected line |
Key Features
| Feature | Design Value |

| Bi-directional symmetry | Enables single-device protection of AC-coupled interfaces (RS-485, CAN, Ethernet PHY) without external polarity logic |
| RoHS-compliant matte tin plating | Supports Pb-free reflow profiles (JEDEC J-STD-020) with no voiding or dewetting risk on OSP or ENIG PCB finishes |
| UL 94V-0 flammability rating | Meets safety requirements for enclosed industrial enclosures and Class 2 power-limited circuits |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
|
Use Scenario: Protects 24V digital input channels in programmable logic controllers against induced surges from relay coil flyback and ESD events. IC Role / Device Role / Timing Role: Bi-directional TVS placed between field input and optocoupler input, clamping transients before they reach isolation barrier. Use Value: Maintains signal integrity with <5µA leakage at 24V, ensuring accurate logic-level detection while surviving repeated 1kV/500A surge tests. |
Use Scenario: Shields LIN bus transceivers and sensor supply lines in body control modules from battery dump and load-dump transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12V rail feeding LIN PHY and Hall-effect sensors. Use Value: Clamps 36V standoff to ≤58.1V within nanoseconds, preventing latch-up in 3.3V/5V microcontrollers powered from same rail. |
| Telecom Power Feeds | Renewable Energy Monitoring |
|
Use Scenario: Guards PoE-powered remote units (e.g., IP cameras) against induced surges on 48V DC feed lines from nearby lightning strikes. IC Role / Device Role / Timing Role: Secondary-stage TVS after primary GDT, absorbing residual energy not shunted by upstream protection. Use Value: 600W rating handles residual 10/700µs telecom surges; bi-directionality accommodates polarity reversal during fault conditions. |
Use Scenario: Protects RS-485 communication lines between solar inverters and monitoring gateways exposed to outdoor surge environments. IC Role / Device Role / Timing Role: Bi-directional TVS on differential A/B lines, referenced to local ground plane near connector entry. Use Value: Symmetric clamping (±58.1V) preserves common-mode noise rejection while limiting differential overvoltage to safe levels for transceiver inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA-T | Same electrical specs; tape-and-reel packaging differs (5,000/reel vs. 3,000/reel); identical SMB case and RoHS compliance | No functional difference; suited for high-volume SMT lines requiring larger reels | Select when optimizing for feeder change frequency and line uptime in mass production |
| SMCJ36CA-13-F | Higher 1500W peak power rating; larger SMC package (7.11 × 6.22 mm); same 36V standoff and bi-directional configuration | Better suited for higher-energy threats (e.g., ISO 7637-2 Pulse 5a); requires larger PCB footprint and thermal relief | Choose when system-level testing reveals insufficient margin with 600W rating or when board layout allows SMC footprint |
Compared with SMBJ36CA-T, the -13-F variant offers tighter reel quantity alignment with mid-volume production runs; versus SMCJ36CA-13-F, it trades surge capacity for compactness-critical where space-constrained PCBs must meet IEC 61000-4-2/4-4 but not full ISO 7637-2 Level 5.

FAQ
What is the meaning of the 'C' in SMBJ36CA?
The 'C' suffix denotes bi-directional functionality. Unlike uni-directional SMBJ36A, the SMBJ36CA provides symmetrical clamping for both positive and negative transients, making it suitable for AC-coupled lines such as RS-485, CAN, or audio interfaces where polarity is undefined or reversible.
Can SMBJ36CA-13-F be used in place of a uni-directional TVS?
Yes, but only if the circuit does not rely on DC blocking or polarity-sensitive conduction. The bi-directional device will conduct during both voltage polarities, so it must not be placed in series with DC-biased paths where reverse conduction would cause malfunction. For pure overvoltage clamping on floating or AC lines, it is fully interchangeable.
What is the maximum allowable PCB pad temperature during reflow soldering?
The SMBJ36CA-13-F is qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Peak temperature must not exceed 260°C for ≤10 seconds, with ramp rates ≤3°C/s. The matte tin finish ensures wetting reliability on OSP, ENIG, and immersion silver PCB finishes without intermetallic formation issues.
How does its clamping performance compare to SMAJ36CA?
SMBJ36CA delivers 600W peak power and 58.1V clamping at 10.3A, whereas SMAJ36CA is rated for 400W and clamps at 58.1V only up to 6.9A. The SMBJ's larger package enables higher surge handling and better thermal dissipation-critical for applications exposed to repeated or high-energy transients like industrial motor drives.
