Product details
Overview
SMA5J6.5CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients 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 11.2 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J6.5CA-E3/61 datasheet, SMA5J6.5CA-E3/61 pinout, SMA5J6.5CA-E3/61 application, or SMA5J6.5CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, 500 W surge rating at 10/1000 µs, RoHS-compliant E3 termination, AEC-Q101 qualification eligibility, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS diode operates symmetrically in both polarities, with no polarity marking on the device body. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients per IEC 61000-4-2 and ISO 16750-2.
The SMA5J6.5CA-E3/61 delivers 11.2 V clamping at 44.6 A (10/1000 µs), with thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting operation from –55 °C to +150 °C. It meets MSL Level 1 (260 °C reflow peak) and is qualified to JESD201 Class 2 whisker test standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins; sets protection threshold for 5 V–6.5 V logic and interface rails. |
| VBR min/max | 7.22 V / 7.98 V at 10 mA - verified breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| IPPM | 44.6 A - peak surge current handling at 10/1000 µs waveform; determines survivability against 500 W transient energy events. |
| VC | 11.2 V - maximum clamped voltage across device at IPPM; defines worst-case overvoltage seen by protected downstream circuitry. |
| PPPM | 500 W - peak pulse power rating (10/1000 µs); enables robust protection against automotive load-dump and inductive switching surges. |
| TJ max | +150 °C - maximum junction temperature; supports high-temperature environments including under-hood automotive and industrial motor drives. |
| Package | SMA (DO-214AC) - surface-mount package with 5.0 mm × 5.0 mm pad layout; optimized for automated placement and thermal dissipation. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD22-B102; bidirectional type with no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Case (body) | Thermal and mechanical mounting surface | Non-electrical; provides mechanical anchoring and heat transfer to PCB copper pads (0.2" × 0.2" recommended per terminal). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signal lines, differential buses (e.g., RS-485), and floating power domains without polarity constraints. |
| 500 W peak pulse power | Supports compliance with ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surge immunity requirements. |
| Glass-passivated junction | Ensures stable VBR tolerance (±5 % typical), low leakage (<500 µA at VWM), and long-term reliability under repeated surge stress. |
| MSL Level 1 rating | Permits standard SMT reflow profiles up to 260 °C peak without preconditioning - eliminates moisture sensitivity handling overhead. |
| AEC-Q101 qualification option | Available in HE3 suffix variant; validates suitability for automotive powertrain and chassis applications requiring zero-defect reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.5CA-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMA package; same thermal and surge performance. | Required where halogen-free material compliance (e.g., IPC-1752) is mandated in aerospace or green electronics programs. | Select SMA5J6.5CA-M3/61 when halogen-free bill-of-materials is contractually required; otherwise SMA5J6.5CA-E3/61 offers broader commercial availability. |
| SMA6J6.5CA-E3/61 | 600 W peak pulse power (vs. 500 W), higher IPPM (50.5 A), same VWM/VC, identical SMA package and footprint. | Preferred for designs targeting higher immunity margins (e.g., ISO 16750-2 Pulse 5a) or extended lifetime under repetitive surge stress. | Choose SMA6J6.5CA-E3/61 if system-level surge testing exceeds 500 W requirements; note that higher power rating does not affect PCB layout or signal routing. |
Compared with SMA5J6.5CA-E3/61, SMA5J6.5CA-M3/61 offers identical protection performance with halogen-free construction, while SMA6J6.5CA-E3/61 increases surge margin by 20 % without changing board space - enabling future-proofing or compliance with stricter OEM surge specifications.

FAQ
What is the polarity configuration of SMA5J6.5CA-E3/61?
The SMA5J6.5CA-E3/61 is a bidirectional TVS diode with symmetrical anode/cathode terminals and no polarity marking on the SMA (DO-214AC) package body. This allows it to clamp transient voltages of either polarity equally - making SMA5J6.5CA-E3/61 ideal for protecting AC-coupled signals, differential buses, and floating power domains without orientation concerns during assembly.
Does SMA5J6.5CA-E3/61 meet automotive qualification standards?
The base SMA5J6.5CA-E3/61 is RoHS-compliant and commercial-grade; however, the AEC-Q101-qualified version is available as SMA5J6.5CAHE3_A/E3 (with HE3 suffix). That variant undergoes stress testing per AEC-Q101 including HTGB, HTRB, and temperature cycling - confirming SMA5J6.5CA-E3/61's design foundation supports automotive use when ordered with appropriate suffixes and packaging codes.
What is the maximum clamping voltage of SMA5J6.5CA-E3/61 at rated surge current?
The SMA5J6.5CA-E3/61 has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current (IPPM) of 44.6 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Can SMA5J6.5CA-E3/61 be used in place of unidirectional TVS diodes?
No - SMA5J6.5CA-E3/61 is strictly bidirectional and lacks a defined cathode band; it cannot replace unidirectional types like SMA5J6.5A-E3/61 in DC-biased circuits where forward conduction must be blocked. Using SMA5J6.5CA-E3/61 in such applications risks unintended forward conduction during normal operation. Always match device polarity (unidirectional vs. bidirectional) to circuit topology and bias conditions when selecting SMA5J6.5CA-E3/61.
What is the thermal resistance specification for SMA5J6.5CA-E3/61?
The SMA5J6.5CA-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W, measured on the standard 0.2" × 0.2" copper pad layout per terminal. These values enable accurate thermal modeling of power dissipation during transient events and confirm SMA5J6.5CA-E3/61's suitability for high-temperature ambient environments up to +150 °C junction temperature.
