Product details
Overview
SMAJ130CA-13 from Diodes Incorporated is a bi-directional 400W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 130V reverse standoff voltage (VRWM), 144–159V breakdown voltage (VBR), 209V maximum clamping voltage (VC) at 1.9A peak pulse current (IPP), and operates from –55°C to +150°C - used in industrial power supply input stages and telecom line card surge protection.
For engineers reviewing the SMAJ130CA-13 datasheet, SMAJ130CA-13 pinout, SMAJ130CA-13 application, or SMAJ130CA-13 equivalent, key selection criteria include clamping voltage margin vs. protected IC VCC rating, unidirectional/bi-directional polarity requirement, peak pulse power derating above 25°C, and compatibility with automated SMT assembly using SMA package footprint.
Technical Context
This bi-directional TVS diode uses glass-passivated junction construction to achieve fast response time (<1 ps) and stable clamping under repetitive transients. Its symmetrical I-V characteristic enables protection against both positive and negative polarity surges without external polarity management.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) standards when applied with appropriate PCB layout and series impedance. Clamping performance is specified at 1.0mA test current (IT) and validated with 8.3ms half-sine waveform per JEDEC method.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 8.3ms surge events without failure under defined thermal conditions |
| Reverse Standoff Voltage (VRWM) | 130V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 144–159V @ 1.0mA - onset of avalanche conduction; defines minimum clamping threshold |
| Max Clamping Voltage (VC) | 209V @ 1.9A IPP - upper voltage limit seen by downstream circuit during rated surge |
| Operating Temperature | –55°C to +150°C - supports deployment in automotive engine bays and industrial motor drives |
| Package | SMA (DO-214AC) - standardized 2-pin SMT outline with 4.80–5.59mm body length and 2.01–2.30mm terminal spacing |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with UL 94V-0 flammability rating and cathode band omitted (bi-directional configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Bi-directional avalanche terminals | Interchangeable; no polarity marking; conducts symmetrically for ± transients |
| Case | Non-electrical mechanical structure | No internal connection; serves only as thermal path and mounting interface |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enables stable, low-leakage avalanche behavior across temperature and lifetime |
| 400W peak pulse rating | Supports Level 4 IEC 61000-4-5 (4kV/2Ω) surge testing on 12–48V DC rails |
| RoHS-compliant matte tin plating | Ensures solderability per MIL-STD-202 Method 208 and compatibility with lead-free reflow |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected 150V-rated MOSFETs or gate drivers |
Applications
| Industrial PLC I/O Protection | Telecom Line Card Surge Suppression |
|---|---|
Use Scenario: Protects 24V digital input modules from induced lightning surges on field wiring. IC Role / Device Role / Timing Role: Bi-directional TVS placed between signal line and ground, clamping transients before they reach optocoupler input stage. Use Value: Limits voltage to ≤209V during 1.9A surge, preserving optocoupler CTR and isolation barrier integrity. | Use Scenario: Shields Ethernet PHY interface pins on DSLAM line cards from AC power cross-talk and EFT bursts. IC Role / Device Role / Timing Role: Parallel-connected TVS on differential pairs, suppressing common-mode surges without distorting 100MHz signal integrity. Use Value: Sub-1ps response ensures clamping occurs before PHY receiver latch windows, preventing bit errors. |
| Automotive Body Control Module (BCM) | Renewable Energy Inverter DC Link |
Use Scenario: Guards LIN bus transceiver pins against load dump and ISO 7637-2 pulse 5a/b transients. IC Role / Device Role / Timing Role: Bi-directional clamp referenced to vehicle chassis ground, absorbing bidirectional spikes on 12V supply rail. Use Value: Withstands 150°C ambient and maintains <5µA leakage at 130V, ensuring low-power sleep mode reliability. | Use Scenario: Protects IGBT gate driver inputs from switching-induced dv/dt coupling on 600V DC link in solar inverters. IC Role / Device Role / Timing Role: Mounted directly at driver IC package, shunting high-frequency ringing before it couples into logic thresholds. Use Value: 209V clamping prevents false triggering of gate drivers rated for 250V absolute max, improving system uptime. |
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-13 | Same VRWM/VBR/VC specs but 600W PPK rating and SMB (DO-214AA) package - 25% larger footprint | Better suited for higher-energy surges where board space allows larger package | Select when surge test level exceeds 400W or thermal mass requirements demand lower junction temperature rise |
| SMCJ130CA-13 | Same electrical specs, 1500W PPK, SMC (DO-214AB) package - 50% larger than SMA | Used in primary-side AC/DC front-end protection where energy absorption dominates size constraints | Choose when protecting upstream rectifier bridges or meeting IEC 61000-4-5 Level 5 (10kV/2Ω) |
Compared with SMBJ130CA-13 and SMCJ130CA-13, the SMAJ130CA-13 delivers optimal balance of 400W surge handling, compact SMA footprint, and cost efficiency for secondary-side 24–48V DC protection - making it preferred for space-constrained industrial and telecom modules.

FAQ
What does the "C" suffix in SMAJ130CA-13 indicate?
The "C" denotes bi-directional functionality: the device provides symmetrical clamping for both positive and negative voltage transients without polarity sensitivity. Unlike unidirectional variants (e.g., SMAJ130A-13), it lacks a cathode band marking and exhibits matched VBR in either direction, enabling simplified layout on AC-coupled or floating signal lines.
How is the 209V clamping voltage measured and what does it mean for circuit design?
The 209V clamping voltage (VC) is measured at 1.9A peak pulse current (IPP) using an 8.3ms half-sine waveform per JEDEC test method. This value represents the maximum voltage imposed on protected circuitry during that specific surge event - designers must ensure all downstream components have voltage ratings exceeding 209V to avoid damage or malfunction.
Can SMAJ130CA-13 be used in place of a unidirectional TVS like SMAJ130A-13?
Yes, but only if the application requires bi-directional protection or has no DC bias - for example, AC signal lines or floating grounds. In DC-biased circuits (e.g., 130V supply rail), using the bi-directional version may allow forward conduction during normal operation, causing excessive leakage or thermal stress; unidirectional types are preferred for such cases.
What is the thermal derating behavior above 25°C ambient?
Per Figure 1 in the datasheet, peak pulse power derates linearly from 100% at 25°C to ~50% at 125°C ambient. At 75°C, it retains ~80% of 400W rating. This reflects junction-to-ambient thermal resistance limitations - effective PCB copper pour and airflow must be considered to maintain clamping performance under sustained high-temperature operation.
