Product details
Overview
SMAJ10CA-M3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 23.5 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the SMAJ10CA-M3/5A datasheet, SMAJ10CA-M3/5A pinout, SMAJ10CA-M3/5A application, or SMAJ10CA-M3/5A equivalent, this device delivers verified bidirectional surge suppression, halogen-free RoHS compliance (M3 suffix), AEC-Q101 qualification readiness, and compatibility with automated SMT placement on PCBs requiring robust ESD and lightning-induced transient protection.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ps), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device is rated for 150 °C maximum junction temperature, exhibits ±0.078 %/°C temperature coefficient of VBR, and achieves thermal resistance of 120 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads - enabling reliable operation in high-temperature automotive engine control units and industrial motor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA-E3/5A | Same electrical specs; RoHS-compliant but contains brominated flame retardants (non-halogen-free) | Approved for commercial-grade industrial equipment where halogen-free mandate does not apply | Select when cost sensitivity outweighs halogen-free requirement and AEC-Q101 is not needed |
| SMAJ10CAHM3_A/I | Identical M3 halogen-free construction; AEC-Q101 qualified; supplied in 13" tape-and-reel (7500 pcs) | Required for automotive production programs needing PPAP documentation and automotive-grade traceability | Choose for Tier 1 automotive designs requiring full qualification evidence and extended reel quantity |
Compared with SMAJ10CA-M3/5A, the E3 variant trades halogen-free status for lower unit cost in commercial applications, while the HM3_A/I variant adds AEC-Q101 validation and larger reel packaging - making SMAJ10CA-M3/5A the optimal balance of automotive-readiness, halogen-free compliance, and standard 7500-piece logistics for mid-volume industrial designs.

FAQ
What is the clamping voltage of SMAJ10CA-M3/5A at its rated peak pulse current?
The SMAJ10CA-M3/5A has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 23.5 A, measured using the standardized 10/1000 μs waveform. This value is confirmed in the Vishay datasheet (Document Number: 88390, Rev. 09-Jan-2024) and defines the upper voltage limit imposed on protected circuitry during surge events. The SMAJ10CA-M3/5A maintains this clamping performance across its full operating temperature range.
Is SMAJ10CA-M3/5A suitable for automotive applications?
Yes - SMAJ10CA-M3/5A uses halogen-free, RoHS-compliant construction (M3 suffix) and is part of the AEC-Q101-qualified SMAJ family. While the base SMAJ10CA-M3/5A itself is commercial-grade, its HM3_X variants (e.g., SMAJ10CAHM3_A/I) are fully AEC-Q101 qualified. Engineers can confidently deploy SMAJ10CA-M3/5A in automotive subsystems such as body control modules and sensor interfaces where halogen-free compliance is required and qualification is managed at system level.
How does the bidirectional design of SMAJ10CA-M3/5A affect its PCB layout?
The SMAJ10CA-M3/5A has no polarity marking and identical electrical behavior in both directions, eliminating orientation constraints during PCB layout. Unlike unidirectional TVS diodes, it requires no cathode band alignment - simplifying automated placement and reducing assembly errors. This symmetry also allows single-device protection of AC-coupled or differential signal paths, such as RS-485 or Ethernet pairs, without additional routing complexity. The SMAJ10CA-M3/5A's DO-214AC footprint remains unchanged regardless of mounting direction.
What is the thermal resistance of SMAJ10CA-M3/5A, and how does it impact power dissipation?
SMAJ10CA-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value determines steady-state power handling: at 25 °C ambient, its 3.3 W continuous power dissipation (PD) results in ~400 °C junction rise - confirming that SMAJ10CA-M3/5A is intended for transient-only operation, not continuous DC power. Its thermal design assumes short-duration surges, not sustained loading.
Does SMAJ10CA-M3/5A meet any international surge immunity standards?
SMAJ10CA-M3/5A is engineered to support compliance with key surge immunity standards including IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge), particularly Level 4 (4 kV line-to-earth). Its 400 W peak pulse power rating, 17.0 V clamping voltage, and sub-nanosecond response enable effective protection against waveforms defined in these standards. While the device itself is not "certified" to a standard, its parameters align with test requirements for end-equipment certification when applied per Vishay's recommended layout guidelines.
