Product details
Overview
SMAJ16CA-M3/61 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 16 V standoff voltage (VWM), 26.0 V maximum clamping voltage at 15.4 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMAJ16CA-M3/61 datasheet, SMAJ16CA-M3/61 pinout, SMAJ16CA-M3/61 application, or SMAJ16CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while fast response time (<1.0 ps) limits transient energy delivered to downstream components.
The device delivers 400 W peak pulse power up to 78 V, derating to 300 W above that threshold; thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), supporting reliable operation under repetitive surge conditions when mounted per recommended pad layout.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs M3) | Preferred for commercial-grade non-automotive designs where halogen content is unrestricted | Select E3 for cost-sensitive consumer applications; M3 required for automotive or green-certified industrial products |
| SMBJ16CA-M3 | Higher 600 W PPPM rating; larger SMB (DO-214AA) package; same VWM/VC | Better suited for higher-energy surges (e.g., IEC 61000-4-5 Level 5); requires larger PCB area | Choose SMBJ16CA-M3 when system-level testing demands >400 W surge handling; SMAJ16CA-M3 fits space-constrained layouts |
Compared with SMAJ16CA-E3/61, the M3 variant adds halogen-free compliance without performance trade-offs; versus SMBJ16CA-M3, SMAJ16CA-M3 offers identical clamping performance in a 30 % smaller footprint - critical for dense PCBs in automotive ECUs and IoT edge nodes.

FAQ
What is the clamping voltage of SMAJ16CA-M3/61 at its rated peak pulse current?
The SMAJ16CA-M3/61 has a maximum clamping voltage (VC) of 26.0 V at its specified peak pulse current (IPPM) of 15.4 A, measured under the standard 10/1000 μs waveform. This value ensures downstream ICs see limited overvoltage during surge events, and it is validated per JEDEC test conditions with proper PCB thermal management.
Is SMAJ16CA-M3/61 suitable for automotive applications?
SMAJ16CA-M3/61 is halogen-free and RoHS-compliant but not AEC-Q101 qualified in this specific M3/61 configuration. For automotive use, select the HM3 variant (e.g., SMAJ16CAHM3_A/H), which carries full AEC-Q101 qualification. The SMAJ16CA-M3/61 remains appropriate for non-safety-critical automotive subsystems where qualification is not mandated.
How does the bidirectional nature of SMAJ16CA-M3/61 affect its circuit placement?
Because SMAJ16CA-M3/61 is bidirectional, it has no cathode marking and can be placed across any two nodes needing symmetrical overvoltage protection - such as differential signal pairs (RS-485, CAN), AC power rails, or ungrounded sensor outputs. No orientation check is needed during assembly, reducing SMT error risk.
What is the thermal resistance of SMAJ16CA-M3/61, and how does it impact layout?
SMAJ16CA-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead (RθJL) of 30 °C/W. To maintain safe operation under repetitive surges, Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal - undersized pads will cause excessive junction temperature rise and premature failure.
Does SMAJ16CA-M3/61 meet moisture sensitivity level requirements for lead-free reflow?
Yes, SMAJ16CA-M3/61 meets MSL Level 1 per J-STD-020, with a maximum reflow peak temperature of 260 °C. This allows indefinite floor life and eliminates pre-baking requirements - streamlining high-volume SMT production and reducing process complexity compared to higher-MSL components.
