Product details
Overview
SMA5J13CAHE3/5A 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 stand-off voltage (VWM), 21.5 V maximum clamping voltage (VC) at 23.3 A peak pulse current (IPPM), and 500 W peak pulse power (10/1000 µs waveform), commonly deployed to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMA5J13CAHE3/5A datasheet, SMA5J13CAHE3/5A pinout, SMA5J13CAHE3/5A application, or SMA5J13CAHE3/5A equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, thermal resistance (RθJA = 80 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 14.4 V and 15.9 V at 1 mA test current. Its low incremental surge resistance enables rapid voltage clamping during fast transients such as ISO 7637-2 pulses or IEC 61000-4-5 surges.
The device is rated for junction temperatures from −55 °C to +150 °C, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and uses glass-passivated silicon junction construction for stable leakage performance (<1.0 µA at VWM) and long-term reliability under repetitive surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Voltage at which device enters avalanche breakdown; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 21.5 V at 23.3 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 500 W - Maximum non-repetitive surge energy absorption capability; validates suitability for automotive load-dump immunity. |
| IPPM (Peak Pulse Current) | 23.3 A - Surge current level at which VC is measured; used with PCB trace impedance to estimate actual clamping behavior. |
| TJmax | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| RθJA | 80 °C/W - Thermal resistance from junction to ambient; informs derating requirements when mounted on standard 5 mm × 5 mm pads. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Case conforms to UL 94 V-0 flammability rating; matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 mechanical robustness standards.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13CA-M3/5A | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected where halogen-free material compliance is mandated by OEM or regional regulation. | Direct substitution if halogen-free content is required; same thermal and surge performance. |
| SMCJ13CAHE3/5A | Same VWM/VC ratings but in larger SMC (DO-214AB) package; higher IPPM (33.3 A) and PPPM (1500 W). | Used where higher surge energy handling is needed (e.g., main power rail vs. signal line); requires larger PCB footprint. | Select when system-level surge testing exceeds 500 W; not drop-in due to different package and pad layout. |
Compared with SMA5J13CAHE3/5A, the M3/5A offers identical protection performance with halogen-free materials, while the SMCJ13CAHE3/5A provides 3× higher surge capacity at the cost of board space-enabling tiered design strategies from signal-line to power-rail protection.

FAQ
What does the "CA" suffix indicate in SMA5J13CAHE3/5A?
The "CA" suffix denotes a bidirectional configuration: SMA5J13CAHE3/5A provides symmetrical clamping in both forward and reverse directions, with identical VBR, VC, and IPPM characteristics regardless of polarity. This eliminates orientation constraints during PCB layout and supports AC-coupled or floating signal line protection-unlike unidirectional "A" variants that require cathode alignment.
Is SMA5J13CAHE3/5A qualified for automotive use?
Yes, SMA5J13CAHE3/5A carries AEC-Q101 qualification, confirmed in Vishay's ordering code "HE3" (RoHS-compliant + AEC-Q101). It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance per AEC-Q101 Rev D, making it suitable for under-hood and chassis-mounted automotive modules.
What is the maximum clamping voltage of SMA5J13CAHE3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J13CAHE3/5A is 21.5 V, measured at 23.3 A peak pulse current using the standardized 10/1000 µs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMA (DO-214AC) package affect thermal performance of SMA5J13CAHE3/5A?
The SMA package delivers a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value assumes optimal PCB layout per Vishay's recommended pad dimensions; reducing pad area increases RθJA, lowering allowable surge repetition rate and requiring derating above 25 °C ambient per fig. 2 in the datasheet.
Can SMA5J13CAHE3/5A replace SMA5J13AHE3/5A in a design?
No-SMA5J13CAHE3/5A is bidirectional while SMA5J13AHE3/5A is unidirectional. Substituting them without layout review risks incorrect clamping behavior on AC or floating nodes. The unidirectional version has a cathode band and conducts only in reverse bias; the CA variant has no polarity marking and clamps equally in both directions.
