Product details
Overview
SMA5J6.5CA-M3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection on signal and power lines. It features a 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 44.6 A peak pulse current (IPPM), and clamps to ≤11.2 V at rated surge. It is used to protect MOSFETs, sensor interfaces, and automotive ECUs against ESD and load-dump transients.
For engineers reviewing the SMA5J6.5CA-M3/61 datasheet, SMA5J6.5CA-M3/61 pinout, SMA5J6.5CA-M3/61 application, or SMA5J6.5CA-M3/61 equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating with low clamping voltage, halogen-free RoHS-compliant construction (M3 suffix), and compatibility with automated SMT placement on consumer, industrial, and AEC-Q101-qualified automotive designs.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient events exceeding VWM = 6.5 V, it avalanches symmetrically in both directions to limit voltage across protected circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<500 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
Thermal performance is defined by RθJA = 80 °C/W (on 5.0 mm × 5.0 mm copper pads) and TJ(max) = +150 °C. The bidirectional configuration eliminates polarity concerns in AC-coupled or differential signal paths, and its DO-214AC outline enables high-power density in surface-mount layouts without discrete heat sinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum continuous reverse operating voltage before conduction begins; sets minimum working margin for protected line. |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - Confirmed avalanche onset range; guarantees reliable triggering above VWM with tight tolerance. |
| VC @ IPPM | ≤11.2 V at 44.6 A - Clamped voltage under 500 W 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling per single transient; defines survivability against ISO 7637-2 Pulse 1/2a/5a or IEC 61000-4-5 surges. |
| IPPM | 44.6 A - Peak surge current supported at VC; directly correlates with PCB trace width and fuse coordination requirements. |
| TJ(max) | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| Package | SMA (DO-214AC) - Standardized 2-pin SMT outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height; compatible with JEDEC MS-013. |

IC Role / Device Role / Timing Role: Shunt TVS diode placed between signal line and ground, clamping transients before they reach ADC front-end or op-amp buffer. Use Value: Limits voltage to ≤11.2 V during 500 W surges, preventing latch-up or permanent damage to 3.3 V/5 V signal chain components. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to inductive switching noise from solenoids and contactors. IC Role / Device Role / Timing Role: Bidirectional clamp across isolated 24 V DC input terminals, suppressing fast-rising spikes induced by relay coil de-energization. Use Value: Fast response (<1 ns) and low clamping voltage ensure microcontroller GPIOs remain within absolute maximum ratings during repetitive 40 A surge events. |
| Consumer USB Port ESD Protection | Telecom Line Interface Protection |
|
Use Scenario: Secondary-level surge suppression on USB 2.0 data lines (D+/D−) in set-top boxes and smart displays subjected to system-level ESD. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed after primary common-mode choke, providing differential-mode transient clamping. Use Value: 6.5 V VWM avoids signal distortion on 3.3 V logic; symmetrical breakdown ensures equal protection for both polarities of ESD contact discharge. |
Use Scenario: Overvoltage protection on POTS line interface circuits in VoIP gateways and DSL modems exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary shunt protector across tip/ring pair, coordinated with gas discharge tube (GDT) for staged surge handling. Use Value: 500 W rating handles IEC 61000-4-5 Combination Wave (10/700 µs) surges up to 4 kV; DO-214AC footprint supports high-voltage creepage spacing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5CA-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3). | Preferred for commercial-grade applications where halogen content is unrestricted. | Select E3 when cost sensitivity outweighs halogen-free requirement; verify compliance with IPC-1752A Category B reporting. |
| SMA6J6.5CA-M3/61 | Higher PPPM = 600 W; same VWM, VBR, and package; slightly higher VC = 11.7 V. | Suitable for designs requiring extended surge margin beyond 500 W, e.g., heavy-duty industrial motor drives. | Choose SMA6J6.5CA-M3/61 only if validated test data confirms need for >500 W rating; avoid unnecessary overdesign due to higher clamping voltage. |
Compared with SMA5J6.5CA-M3/61, the E3 variant offers identical protection performance at lower material cost but lacks halogen-free certification, while the SMA6J6.5CA-M3/61 delivers 20 % higher surge capacity at the expense of 0.5 V higher clamping - critical for 3.3 V logic interfaces where voltage margin is constrained.

FAQ
What is the polarity configuration of SMA5J6.5CA-M3/61?
The SMA5J6.5CA-M3/61 is a bidirectional TVS diode with symmetrical terminals and no polarity marking. Unlike unidirectional variants (e.g., SMA5J6.5A), it conducts identically in both directions above VBR, making it ideal for AC signal lines, differential buses, and floating power rails where orientation cannot be guaranteed during assembly.
Does SMA5J6.5CA-M3/61 meet AEC-Q101 qualification?
The base part SMA5J6.5CA-M3/61 is not AEC-Q101 qualified. However, Vishay offers the automotive-grade variant SMA5J6.5CAHM3_X (where "_X" denotes revision code A, B, etc.), which carries full AEC-Q101 qualification and shares identical electrical specs and package. Always specify HM3 suffix and revision code when automotive qualification is required for SMA5J6.5CA-M3/61 applications.
What is the maximum clamping voltage for SMA5J6.5CA-M3/61 under surge conditions?
The SMA5J6.5CA-M3/61 clamps to a maximum of 11.2 V when subjected to its rated 44.6 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet Document Number 88875, ensuring predictable voltage limiting for downstream 3.3 V or 5 V ICs.
How does the M3 suffix affect the material composition of SMA5J6.5CA-M3/61?
The M3 suffix on SMA5J6.5CA-M3/61 indicates halogen-free, RoHS-compliant construction per IPC-1752A requirements. The molding compound contains no brominated or chlorinated flame retardants, and tin-plated leads meet JESD 22-B102 solderability standards. This distinguishes it from the E3 variant, which is RoHS-compliant but not halogen-free.
Can SMA5J6.5CA-M3/61 be used in place of a unidirectional TVS like SMA5J6.5A?
No - SMA5J6.5CA-M3/61 is bidirectional and must not replace unidirectional parts like SMA5J6.5A in DC-biased circuits without redesign. In a unidirectional application (e.g., 12 V supply rail to ground), SMA5J6.5CA-M3/61 would conduct during normal forward bias, causing excessive leakage and potential failure. Always match polarity type to circuit topology: use CA for AC/differential, A for DC/unidirectional.
