Product details
Overview
SMA6J17A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping transient overvoltages on power and signal lines. It features a 17 V stand-off voltage (VWM), 18.9–20.9 V breakdown voltage (VBR at IT = 1 mA), 26.7 V maximum clamping voltage at 111 A (10/1000 μs), 600 W peak pulse power rating, and operates across –55 °C to +150 °C junction temperature range - used to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J17A-M3/61 datasheet, SMA6J17A-M3/61 pinout, SMA6J17A-M3/61 application, or SMA6J17A-M3/61 equivalent, key selection criteria include clamping voltage at rated IPP, unidirectional polarity, MSL Level 1 compliance, halogen-free RoHS status (M3 suffix), and thermal resistance (RθJA = 120 °C/W) for PCB-level surge protection design.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (< 0.2 μA leakage at 17 V), then avalanches sharply above VBR to limit transients. Its dynamic resistance (RD = 0.259 Ω) and low clamping ratio (VC/VBR ≈ 1.41) ensure fast, predictable suppression of 10/1000 μs surges up to 111 A.
Designed for surface-mount automation, the device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, with cathode indicated by a color band. It meets MSL Level 1 per J-STD-020 and achieves UL 94 V-0 flammability rating in its SMA molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line's nominal DC level. |
| VBR (min/max) | 18.9 V / 20.9 V at 1 mA - precise avalanche onset range defining turn-on threshold under transient stress. |
| VC at IPP | 26.7 V at 111 A (10/1000 μs) - clamped voltage seen by downstream circuit during worst-case surge; determines safe margin for IC withstand. |
| PPPM (10/1000 μs) | 600 W - peak transient energy handling capability under standard lightning-surge waveform; defines single-event robustness. |
| IFSM | 50 A - non-repetitive forward surge current rating; supports limited fault-current exposure during system startup or short-circuit events. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in high-ambient industrial environments without derating below 50 °C ambient. |
| RθJA | 120 °C/W - thermal resistance junction-to-ambient on standard 5.0 mm × 5.0 mm copper pads; guides minimum PCB copper area for thermal management. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional polarity, cathode denoted by color band. Dimensions: 4.50 mm × 2.79 mm × 2.20 mm (L × W × H); weight: 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to lower-potential side (e.g., GND or return rail); completes clamping loop during reverse-biased surge event. |
| Cathode | Transient voltage sensing / clamping node | Connected to protected line (e.g., 12 V rail or signal input); avalanche conduction begins here when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant (M3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-201 Class 2 whisker resistance; suitable for green manufacturing and export compliance. |
| MSL Level 1 moisture sensitivity | Zero floor life limitation; can be stored indefinitely at ≤30 °C/85 % RH and mounted without baking prior to reflow. |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes overvoltage overshoot during clamping; reduces risk of damage to 3.3 V or 5 V logic interfaces downstream. |
| 120 °C/W RθJA on standard pads | Enables thermal design with minimal copper area; supports compact layout in space-constrained industrial modules. |
| 50 A IFSM rating | Withstands brief inrush or fault currents without degradation; extends reliability in systems with capacitive loads or motor drives. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J17A-E3/61 | Same electrical specs and package; RoHS-compliant but not halogen-free (E3 vs. M3 suffix); no JESD 201 Class 2 whisker test certification. | Acceptable where halogen-free requirement is absent; may require additional qualification for high-reliability aerospace or medical programs. | Select SMA6J17A-E3/61 only if M3-specific environmental compliance is not mandated by end-customer specifications. |
| SMCJ17A-M3 | Higher power rating (1500 W PPPM @ 10/1000 μs); larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); same VWM/VBR/VC values. | Better suited for higher-energy transients (e.g., 48 V telecom power); requires larger PCB footprint and different pad layout. | Choose SMCJ17A-M3 when surge energy exceeds 600 W or when system-level testing reveals marginal clamping margin with SMA6J17A-M3/61. |
Compared with SMA6J17A-E3/61, the M3/61 variant adds halogen-free assurance and whisker resistance for stringent environmental programs; versus SMCJ17A-M3, it trades power handling for compact size - making SMA6J17A-M3/61 optimal for space-constrained 12–24 V industrial controls where 600 W surge immunity suffices.

FAQ
What is the clamping voltage of SMA6J17A-M3/61 at its rated peak pulse current?
The SMA6J17A-M3/61 has a maximum clamping voltage (VC) of 26.7 V at 111 A peak pulse current under the 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA6J17A-M3/61 maintains this clamping performance across its specified operating temperature range.
Is SMA6J17A-M3/61 suitable for bidirectional transient protection?
No, SMA6J17A-M3/61 is unidirectional only - it conducts avalanche current only when the cathode is at higher potential than the anode. For bidirectional protection (e.g., AC lines or differential data buses), a dedicated bidirectional TVS such as SMBJ17CA-M3/61 must be used. The SMA6J17A-M3/61 datasheet explicitly states "Available in unidirectional polarity only" and shows cathode-band marking, confirming its single-quadrant operation.
What does the "M3" suffix indicate in SMA6J17A-M3/61?
The "M3" suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 2 whisker resistance. It also indicates industrial-grade reliability and compliance with Vishay's material categorization standard (document #99912). Unlike the E3 variant, M3 ensures full halogen-free content and enhanced plating durability - critical for high-reliability and environmentally regulated applications. The SMA6J17A-M3/61 meets both requirements.
Can SMA6J17A-M3/61 be used in place of SMA6J15A-M3/61 without redesign?
No - SMA6J17A-M3/61 has a higher stand-off voltage (17 V vs. 15 V) and breakdown range (18.9–20.9 V vs. 16.7–18.5 V), resulting in higher clamping voltage (26.7 V vs. 23.6 V). Substituting it for SMA6J15A-M3/61 may leave downstream components unprotected during lower-voltage transients. The SMA6J17A-M3/61 is not a drop-in replacement; voltage ratings must match the protected line's nominal and tolerance envelope.
What is the thermal resistance and how does it affect PCB layout for SMA6J17A-M3/61?
The SMA6J17A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value assumes standard JEDEC test board conditions; reducing pad size or omitting thermal vias increases RθJA, risking junction overheating during repeated surges. To maintain reliability, the SMA6J17A-M3/61 should be placed on minimum recommended copper areas and avoid placement near heat sources.
