Product details
Overview
SMA5J13CAHE3/61 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), 14.4–15.9 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤21.5 V at 23.3 A (10/1000 µs waveform), making it suitable for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the SMA5J13CAHE3/61 datasheet, SMA5J13CAHE3/61 pinout, SMA5J13CAHE3/61 application, or SMA5J13CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 500 W surge rating, low clamping voltage under rated IPPM, and compatibility with automated SMT assembly on standard 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during transient events, leveraging an avalanche junction to divert surge current away from protected circuitry. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with no polarity marking required on the SMA package.
The SMA5J13CAHE3/61 is rated for 150 °C maximum junction temperature and exhibits 80 °C/W junction-to-ambient thermal resistance when mounted per recommended pad layout. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing due to matte tin-plated leads.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13CA | Same VWM (13 V), slightly higher VC (22.0 V @ 23.3 A), non-AEC-Q101 qualified, RoHS-compliant only. | Lacks automotive qualification; suitable for commercial/industrial use where AEC-Q101 is not mandated. | Select SMAJ13CA if cost sensitivity outweighs automotive qualification and thermal derating margin is sufficient. |
| ON Semiconductor 1.5SMC13CA | Same VWM and VBR range, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); PPPM = 1500 W. | Higher power rating but requires 70% more board area; not drop-in compatible with SMA footprint. | Choose 1.5SMC13CA only when >500 W surge margin is required and PCB space allows SMC package. |
Compared with SMA5J13CAHE3/61, SMAJ13CA offers identical electrical specs but lacks AEC-Q101 validation, while 1.5SMC13CA delivers triple the surge power at the cost of significantly larger footprint and non-interchangeable mounting - making SMA5J13CAHE3/61 optimal for space-constrained, automotive-qualified designs requiring precise 500 W protection.

FAQ
What is the polarity configuration of SMA5J13CAHE3/61?
The SMA5J13CAHE3/61 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants, it has no cathode marking on the SMA package - both terminals are functionally identical and interchangeable in circuit layout. This configuration is confirmed in the Vishay datasheet Document Number 88875, Section "DEVICES FOR BIDIRECTION APPLICATIONS".
Is SMA5J13CAHE3/61 qualified for automotive applications?
Yes, SMA5J13CAHE3/61 is AEC-Q101 qualified, as indicated by the "HE3" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock, validating its suitability for under-hood and chassis-mounted automotive electronics. The datasheet explicitly states "AEC-Q101 qualified available" and lists HE3 as the automotive ordering code.
What is the maximum clamping voltage of SMA5J13CAHE3/61 under surge conditions?
The maximum clamping voltage (VC) of SMA5J13CAHE3/61 is 21.5 V, measured at the peak pulse current (IPPM) of 23.3 A using the standardized 10/1000 µs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number 88875, page 2) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does SMA5J13CAHE3/61 require special PCB layout considerations?
Yes - SMA5J13CAHE3/61 must be mounted on minimum recommended copper pads: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal, as specified in the "MECHANICAL DATA" section. This pad size ensures adequate heat dissipation and maintains the rated 500 W peak pulse power; smaller pads cause thermal derating and reduced surge capability per Figure 2 in the datasheet.
What does the "/61" suffix indicate in SMA5J13CAHE3/61?
The "/61" suffix in SMA5J13CAHE3/61 denotes the preferred packaging option: 7-inch diameter plastic tape and reel, with a base quantity of 1800 units. This is confirmed in the "ORDERING INFORMATION" table of the Vishay datasheet (page 3), where "61" is listed as the package code for that delivery mode - essential for procurement and SMT line setup.
