Product details
Overview
SMA5J13CA-E3/5A from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), 500 W peak pulse power (10/1000 µs), clamping voltage of 21.5 V at 23.3 A IPPM, and operates from –55 °C to +150 °C - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J13CA-E3/5A datasheet, SMA5J13CA-E3/5A pinout, SMA5J13CA-E3/5A application, or SMA5J13CA-E3/5A equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating, DO-214AC thermal performance (RθJA = 80 °C/W), AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical avalanche structure enables identical clamping behavior in both polarities, supporting robust protection against ESD, lightning-induced transients, and inductive switching spikes without polarity sensitivity.
The device is rated for 500 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal derating above 25 °C per Figure 2. Mounting on minimum recommended 0.2" × 0.2" copper pads ensures effective heat dissipation, critical for sustaining repetitive surge events in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 14.4 V min / 15.9 V max at 1 mA - precise avalanche initiation range ensuring predictable turn-on during overvoltage |
| VC (Clamping Voltage) | 21.5 V at IPPM = 23.3 A - limits protected circuit voltage during worst-case 500 W surge, enabling safe IC/MOSFET operation |
| PPPM (Peak Pulse Power) | 500 W (10/1000 µs) - energy-handling capacity for transient suppression in automotive load-dump and ISO 7637-2 compliance |
| ID (Reverse Leakage) | 1.0 µA max at VWM - negligible standby current preserving signal integrity and battery life in always-on systems |
| TJ max | +150 °C - supports under-hood automotive placement and industrial ambient temperature extremes |
| RθJA | 80 °C/W - thermal resistance from junction to ambient on standard PCB pad layout; guides heatsinking requirements |

Use Value: Maintains signal integrity during 12 V system load-dump events (ISO 16750-2) while surviving >1000 surges at rated IPPM due to robust junction construction. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Fast-response transient suppressor across input terminals, limiting voltage to ≤21.5 V during 10/1000 µs surges up to 23.3 A. Use Value: Prevents false triggering and latch-up in microcontroller GPIOs by clamping within 1 ns, with minimal capacitance impact on 10 kHz–1 MHz signal bandwidth. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary-side surge protection on Ethernet PHY power rails and data lines in PoE-powered switches and base stations. IC Role / Device Role / Timing Role: Bidirectional TVS placed between VDD and GND near PHY IC, absorbing coupled transients from cabling and AC/DC converter noise. Use Value: Withstands repeated 500 W surges without degradation, meeting GR-1089-CORE telecom immunity requirements while maintaining <1 µA leakage at 13 V. |
Use Scenario: Input-stage overvoltage protection in USB-C PD adapters and wall chargers subjected to mains-borne surges and hot-plug transients. IC Role / Device Role / Timing Role: Primary clamping device across bulk capacitor input, diverting energy before it reaches primary-side controller and transformer. Use Value: Enables compact design via DO-214AC footprint and eliminates need for external series impedance due to low Rincremental, reducing BOM count and board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Lower PPPM (400 W), higher VC (23.2 V at 17.3 A), same VWM/VBR range and DO-214AC package | Less suitable for ISO 7637-2 Pulse 5a/b or IEC 61000-4-5 Level 4; adequate for consumer-grade ESD-only protection | Select SMAJ13CA only when surge energy demand is ≤400 W and layout constraints prohibit larger packages |
| SMBJ13CA | Same VWM/VBR/VC specs but in SMB (DO-214AA) package; 600 W PPPM rating and lower RθJA (60 °C/W) | Better thermal performance and higher surge margin, but 25 % larger footprint; requires revised pad layout | Choose SMBJ13CA when sustained surge repetition or elevated ambient temperatures (>105 °C) demand superior thermal dissipation |

FAQ
What is the polarity configuration of SMA5J13CA-E3/5A?
The SMA5J13CA-E3/5A is a bidirectional TVS diode with symmetrical avalanche characteristics - it has no cathode/anode designation and clamps identically for positive and negative transients. Unlike unidirectional variants (e.g., SMA5J13A), this part carries the "CA" suffix and lacks polarity marking on the SMA package body.
Does SMA5J13CA-E3/5A meet AEC-Q101 requirements?
The base SMA5J13CA-E3/5A is commercial-grade and RoHS-compliant. However, Vishay offers AEC-Q101 qualified versions under ordering codes SMA5J13CAHE3_X (RoHS + AEC-Q101) or SMA5J13CAHM3_X (halogen-free + AEC-Q101), where "_X" denotes revision letter. SMA5J13CA-E3/5A itself is not AEC-Q101 certified unless ordered with HE3 or HM3 suffix.
What is the maximum clamping voltage for SMA5J13CA-E3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J13CA-E3/5A is 21.5 V, measured at the peak pulse current (IPPM) of 23.3 A using a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can SMA5J13CA-E3/5A be used in place of SMAJ13CA?
SMA5J13CA-E3/5A is not a direct drop-in replacement for SMAJ13CA due to differences in surge capability: SMA5J13CA-E3/5A delivers 500 W PPPM versus 400 W for SMAJ13CA, and clamps at 21.5 V vs. 23.2 V. While both share the same VWM (13 V) and DO-214AC package, the improved performance of SMA5J13CA-E3/5A may require layout review if substituting into an existing SMAJ13CA design.
What PCB pad layout is required for optimal thermal performance of SMA5J13CA-E3/5A?
Vishay specifies mounting SMA5J13CA-E3/5A on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve the rated RθJA of 80 °C/W. Reducing pad size increases thermal resistance and reduces surge current handling; use internal copper planes and thermal vias beneath pads if operating near TJ max (150 °C) or under repetitive surge conditions.
