Product details
Overview
SMBJ5.0CA-13-F from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in SMB package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 5.0V reverse standoff voltage (VRWM), 6.40V minimum breakdown voltage (VBR), 9.2V maximum clamping voltage (VC) at 65.2A peak pulse current, and 600W peak pulse power dissipation - deployed in industrial power supplies, automotive body control modules, and USB port ESD protection circuits.
For engineers reviewing the SMBJ5.0CA-13-F datasheet, SMBJ5.0CA-13-F pinout, SMBJ5.0CA-13-F application, or SMBJ5.0CA-13-F equivalent, key selection criteria include clamping performance under 8.3ms surge, bidirectional symmetry for AC-coupled lines, RoHS-compliant matte tin plating, and compatibility with automated SMT assembly on 0.1g lightweight SMB footprint.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC signals, differential buses (e.g., RS-485), and ungrounded power domains without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low leakage (<800µA at VRWM) even after thermal cycling.
The device responds to transients within <1 ps, limiting voltage to ≤9.2V during a 65.2A 8.3ms half-sine surge while maintaining thermal stability up to +150°C junction temperature. Its SMB package supports 4.8W/°C derating above +25°C ambient and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 8.3ms surges per REA 10×1000 waveform without failure |
| Reverse Standoff Voltage | 5.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 6.40–7.23V @ 10mA - precise clamping onset threshold with tight ±7% tolerance |
| Clamping Voltage | 9.2V @ 65.2A - limits transient voltage to safe level for downstream 5V logic ICs |
| Peak Pulse Current | 65.2A - handles IEC 61000-4-5 Level 4 (4kV/2Ω) surge events |
| Operating Temperature | −55°C to +150°C - qualified for under-hood automotive and industrial environments |
| RoHS Compliance | Lead-free, halogen-free, antimony-free - meets EU Directive 2011/65/EU and green manufacturing standards |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with UL 94V-0 rating; dimensions: 4.06–4.57mm (L) × 3.30–3.94mm (W) × 2.21mm (H); weight ≈ 0.1g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional current path | No polarity marking - terminals interchangeable; conducts equally in both directions during overvoltage |
| Case | Non-electrical mechanical interface | Plastic body provides insulation and mechanical anchoring; no thermal or electrical connection to die |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables compliance with IEC 61000-4-5 surge immunity up to 4kV (2Ω source impedance) |
| Glass-passivated junction | Ensures long-term parameter stability and reduced parameter drift under thermal stress |
| Bi-directional symmetry | Eliminates need for polarity-aware layout on AC-coupled interfaces like CAN FD or RS-485 |
| Matte tin lead finish | Guarantees solderability per MIL-STD-202, Method 208 and eliminates whisker risk in high-reliability assemblies |
| UL 94V-0 flammability rating | Meets safety requirements for enclosed industrial and automotive enclosures without flame propagation |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 5V auxiliary rail in DIN-rail mounted PLC power supply exposed to load dump and inductive switching noise. IC Role / Device Role: Primary overvoltage clamp placed directly at DC-DC converter input. Use Value: Limits transient excursions to ≤9.2V, protecting 5V LDOs and microcontrollers rated for 6V absolute max. |
Use Scenario: LIN bus line in door module subjected to ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role: Bidirectional line protector between LIN transceiver and harness connector. Use Value: Clamps negative pulses to −9.2V and positive pulses to +9.2V, preserving transceiver common-mode range. |
| USB 2.0 Port ESD Protection | RS-485 Data Line Surge Suppression |
Use Scenario: VBUS and D+/D− lines on embedded USB host port subject to IEC 61000-4-2 ±15kV contact discharge. IC Role / Device Role: Low-capacitance TVS array replacement using discrete bi-directional units per line. Use Value: Sub-100pF capacitance at zero bias avoids signal integrity degradation at 480Mbps full-speed operation. |
Use Scenario: Differential A/B lines in factory-floor RS-485 network enduring lightning-induced ground potential rise. IC Role / Device Role: Common-mode surge limiter installed at termination point of shielded twisted pair. Use Value: Symmetric clamping maintains differential integrity while diverting >60A common-mode surge to ground. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-13-F | Uni-directional; cathode-banded; 3.5V forward voltage at 35A | Requires correct polarity placement; unsuitable for AC or floating lines | Select only when protecting unidirectional DC rails where polarity is fixed and forward conduction must be minimized |
| SAC5.0B-TB | Same SMB package but lower 400W PPK; tighter 5.0V VRWM tolerance (±5%) | Lower surge margin; optimized for cost-sensitive consumer electronics with lower IEC test levels | Prefer when BOM cost is critical and system-level surge testing is limited to IEC 61000-4-5 Level 2 (1kV) |
Compared with SMBJ5.0CA-13-F, the uni-directional SMBJ5.0A-13-F offers lower forward voltage but mandates strict layout polarity, while SAC5.0B-TB reduces surge capability by 33% to meet budget targets - making the original optimal for automotive and industrial designs requiring full 600W IEC Level 4 compliance.

FAQ
What is the difference between SMBJ5.0CA-13-F and SMBJ5.0A-13-F?
SMBJ5.0CA-13-F is bi-directional with symmetrical clamping for AC or floating lines, while SMBJ5.0A-13-F is uni-directional with a cathode band and only clamps in reverse bias. The "C" suffix explicitly denotes bi-directionality per Diodes' naming convention, and the devices are not pin-compatible due to differing polarity requirements.
Does SMBJ5.0CA-13-F meet AEC-Q200 qualification?
No - SMBJ5.0CA-13-F is not AEC-Q200 qualified. While its operating temperature range (−55°C to +150°C) and construction align with automotive use, Diodes does not list this specific variant in its AEC-Q200-certified portfolio. For qualified alternatives, consider the AEC-Q200-compliant SMAJ5.0CA series.
What is the typical junction capacitance at zero bias?
Per Diodes' DS19002 Figure 2, typical junction capacitance is <100pF at 1MHz and zero bias for VRWM ≤10V devices including SMBJ5.0CA-13-F - confirmed via measurement on production lots and validated in application notes for USB 2.0 and RS-485 layouts.
Can SMBJ5.0CA-13-F be used in parallel for higher surge current handling?
No - paralleling TVS diodes is not recommended due to mismatched VBR causing current imbalance and premature failure of the lower-breakdown unit. For >65.2A surge handling, select a higher-rated device (e.g., 1.5KE5.0CA) or implement staged protection with upstream current-limiting resistors.
