Product details
Overview
SMBJ130CA-13-F from Diodes Incorporated is a bi-directional 600W transient voltage suppressor (TVS) diode in SMB package, designed for overvoltage protection of DC power rails and signal lines. It features 130V reverse standoff voltage (VRWM), 144V minimum breakdown voltage (VBR), 209V maximum clamping voltage (VC) at 2.9A peak pulse current (IPP), and operates from –55°C to +150°C - used in industrial power supply input stages and telecom interface protection.
For engineers reviewing the SMBJ130CA-13-F datasheet, SMBJ130CA-13-F pinout, SMBJ130CA-13-F application, or SMBJ130CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current capability under IEC 61000-4-5 surge conditions, thermal derating above +25°C, and bi-directional symmetry for AC-coupled or floating-line protection.
Technical Context
This bi-directional TVS diode uses glass-passivated silicon junction construction to deliver fast response (<1 ns) to transients while maintaining low leakage (<5 µA at VRWM) and stable clamping performance across temperature. Its symmetrical breakdown behavior enables protection of differential pairs, RS-485 buses, and ungrounded AC inputs without polarity concerns.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity requirements when properly laid out with minimized trace inductance. Its 600W peak pulse power rating is valid for non-repetitive 8.3 ms half-sine wave pulses at ≤4 pulses/minute, with linear derating above +25°C (4.8 W/°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 8.3 ms surge events per IEC 61000-4-5 Level 4 (4 kV line-earth) |
| Reverse Standoff Voltage | 130 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 144–165.5 V - voltage at which device enters avalanche conduction (tested at 1 mA) |
| Clamping Voltage | 209 V @ 2.9 A - maximum voltage seen by protected circuit during specified surge current |
| Leakage Current | <5 µA @ 130 V - ensures minimal power loss and no interference in standby operation |
| Operating Temperature | –55°C to +150°C - supports deployment in automotive engine bays and industrial motor drives |
| Package | SMB (DO-214AA) - surface-mount outline with 5.0–5.59 mm body length and 2.0–2.5 mm terminal spacing |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case rated UL 94V-0, 0.1 g typical weight, matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional avalanche junction | No polarity marking; either terminal serves as cathode depending on transient polarity |
| Cathode Band (absent) | Non-applicable | Bi-directional variant lacks polarity indicator - terminals are functionally identical |
Key Features

|---|---|
| 600W peak pulse power | Enables robust protection against IEC 61000-4-5 surges up to 4 kV on 2 Ω source impedance |
| Glass-passivated die | Ensures stable electrical parameters and long-term reliability under humidity and thermal cycling |
| Bi-directional symmetry | Eliminates orientation errors during placement and supports AC-coupled or floating interfaces |
| RoHS-compliant & halogen-free | Meets IPC-1752A material declaration requirements for green electronics manufacturing |
Applications
| Industrial Power Input Protection | RS-485 Data Line Protection |
|---|---|
Use Scenario: 24 VDC industrial PLC power entry subjected to load dump and inductive switching transients. IC Role / Device Role: Primary overvoltage clamp placed between VIN and GND, upstream of DC-DC converter input. Use Value: Limits transient excursions to ≤209 V, preventing damage to downstream 36 V-rated input capacitors and controller ICs. |
Use Scenario: Two-wire RS-485 bus in factory automation exposed to ESD and cable discharge events. IC Role / Device Role: Bi-directional TVS across differential pair (A–B) and to ground, absorbing common-mode surges. Use Value: Maintains signal integrity by clamping ±209 V transients without forward conduction, preserving receiver common-mode range. |
| Telecom DSL Line Interface | AC Mains Surge Suppression Stage |
Use Scenario: POTS/DSL splitter front-end handling lightning-induced surges on twisted-pair telephone lines. IC Role / Device Role: First-stage protector between line transformer secondary and codec IC, configured in bi-directional mode. Use Value: Withstands repeated 10/700 µs surges up to 1 kV while adding <1 pF capacitance - no data rate degradation. |
Use Scenario: Secondary-side MOV replacement in Class II AC-DC adapters for enhanced longevity and lower leakage. IC Role / Device Role: Parallel-connected TVS on DC output rail (e.g., 12 V or 24 V) to absorb residual surges passing through primary-side protection. Use Value: Provides precise 209 V clamping vs. MOV's wide tolerance, reducing stress on downstream regulators and load switches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA from Littelfuse (SP1303-01WTG) | Same VRWM (130 V), slightly higher VC (214 V @ 2.9 A), 10% higher leakage (≤10 µA) | Valid for same IEC 61000-4-5 Level 4 use cases but requires margin check on clamping headroom | Prefer when dual-sourcing required and layout accommodates 5 V higher clamping excursion |
| P6SMB130CA from ON Semiconductor | Identical electrical specs (VRWM = 130 V, VC = 209 V @ 2.9 A), same SMB package, RoHS-compliant | Drop-in replacement with identical thermal and mechanical footprint; validated in automotive infotainment power rails | Select for designs requiring AEC-Q200-qualified alternatives or existing ON Semi BOM alignment |
Compared with SMBJ130CA-13-F, SP1303-01WTG trades tighter clamping for higher leakage, while P6SMB130CA offers identical performance with automotive qualification - making it preferable where functional safety documentation or extended temperature validation is required.

FAQ
What is the difference between SMBJ130CA-13-F and SMBJ130A-13-F?
SMBJ130CA-13-F is bi-directional (suffix "C"), meaning it clamps voltage transients of either polarity symmetrically across its terminals. SMBJ130A-13-F is uni-directional, with a defined cathode band and only clamps positive transients relative to cathode. The "C" version eliminates polarity-dependent placement errors and suits AC or floating circuits.
Can SMBJ130CA-13-F be used in parallel for higher surge current handling?
No - paralleling TVS diodes without matched VBR and dynamic impedance causes current imbalance and premature failure. For >2.9 A IPP, select a higher-power part (e.g., 1500W SMCJ series) or implement staged protection with upstream current-limiting resistors or PTCs.
What is the maximum PCB trace length recommended between SMBJ130CA-13-F and protected IC?
Trace inductance directly increases clamping voltage (ΔV = L·di/dt). For reliable ≤209 V clamping, total loop inductance must stay below 15 nH - achievable with ≤5 mm trace length, direct ground plane connection, and no vias in the current path. Use dedicated ground pour beneath the device.
Does SMBJ130CA-13-F require derating in reflow soldering profiles?
No additional derating is needed beyond standard JEDEC J-STD-020 Level 1 moisture sensitivity handling. The SMB package is rated for peak reflow temperatures up to 260°C (per 10 sec), and the device's 150°C TJ max ensures safe operation during standard lead-free reflow cycles with proper thermal mass management.
