Product details
Overview
SMA5J36CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 58.1 V clamping voltage (VC) at 8.6 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the SMA5J36CA-E3/61 datasheet, SMA5J36CA-E3/61 pinout, SMA5J36CA-E3/61 application, or SMA5J36CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix), low incremental surge resistance, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with electrical characteristics defined identically for reverse and forward directions per J-STD-020. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive transients induced by inductive switching or ESD events.
The device is rated for -55 °C to +150 °C operating junction temperature, exhibits 80 °C/W junction-to-ambient thermal resistance (RθJA), and maintains ≤1.0 µA maximum reverse leakage at VWM - critical for low-power sensor signal integrity and battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 3.3 V/5 V/24 V rail protection. |
| VBR min/max | 40.0 V / 44.2 V - Verified breakdown threshold at 1 mA test current; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 58.1 V at 8.6 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress below absolute maximum ratings. |
| PPPM | 500 W - Peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity compliance. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive and industrial environments without derating. |
| Package | SMA (DO-214AC) - Surface-mount package with 5.28 mm × 4.50 mm footprint; compatible with standard reflow profiles and J-STD-002 solderability. |
Pinout & Package
Package: SMA (DO-214AC), bidirectional configuration with no polarity marking - terminals are symmetrical and interchangeable. Case meets UL 94 V-0 flammability rating; matte tin-plated leads comply with JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; clamps voltage surges regardless of polarity - eliminates orientation errors during assembly. |
| Case (cathode band absent) | Thermal and mechanical interface | No cathode band marking confirms bidirectional design; case serves as primary heat path to PCB copper pads per JEDEC layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., RS-485, CAN FD) without polarity constraints. |
| 500 W peak pulse power | Supports robust immunity against lightning-induced surges and inductive load switching transients in industrial control cabinets. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow processing at 260 °C peak without baking - reduces manufacturing overhead. |
| Glass-passivated junction | Ensures long-term reliability and stable VBR drift <±5% over 1000 hrs at TJ = 125 °C - critical for automotive AEC-Q101 qualification path. |
| Low leakage (≤1.0 µA) | Maintains signal fidelity in high-impedance sensor front-ends (e.g., thermocouple, RTD inputs) without loading error. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CA-M3/61 | Halogen-free, RoHS-compliant variant with identical electrical specs and package; same 500 W PPPM and 36 V VWM. | Required for halogen-free BOM compliance in EU medical or consumer products; no performance trade-offs. | Select when regulatory compliance mandates halogen-free materials without altering circuit design or layout. |
| SMA5J36CAHE3_A/61 | AEC-Q101 qualified version with enhanced reliability testing (HTOL, TC, UHAST); identical VWM/VBR/VC but validated for automotive under-hood use. | Qualified for automotive powertrain and chassis modules where zero-failure operation is mandated. | Choose for automotive OEM designs requiring certified qualification evidence - not suitable for cost-sensitive commercial applications. |
Compared with SMA5J36CA-E3/61, the M3/61 offers identical protection performance with halogen-free construction, while the HE3_A/61 adds AEC-Q101 validation for automotive deployment - neither requires PCB changes, but HE3_A/61 incurs higher cost and longer lead times.

FAQ
What is the clamping voltage of the SMA5J36CA-E3/61 at its rated peak pulse current?
The SMA5J36CA-E3/61 has a maximum clamping voltage (VC) of 58.1 V at 8.6 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified at TA = 25 °C on minimum recommended pad layout - ensuring predictable overvoltage limiting for downstream ICs in real-world surge conditions.
Is the SMA5J36CA-E3/61 suitable for automotive applications?
The SMA5J36CA-E3/61 itself is not AEC-Q101 qualified, but it shares identical electrical and thermal specifications with the AEC-Q101-qualified variant SMA5J36CAHE3_A/61. For non-safety-critical automotive subsystems (e.g., infotainment, body electronics), SMA5J36CA-E3/61 may be used with customer validation; however, certified applications require the HE3 suffix version.
How does the bidirectional nature of the SMA5J36CA-E3/61 affect its PCB layout?
The SMA5J36CA-E3/61 has no polarity marking and symmetrical terminals, so PCB layout requires no orientation alignment - both pads are functionally identical. This simplifies automated placement and eliminates risk of reverse installation. Thermal relief and 0.2" × 0.2" copper pads per terminal must still be maintained for reliable 500 W surge dissipation.
What is the maximum reverse leakage current for the SMA5J36CA-E3/61 at its stand-off voltage?
The SMA5J36CA-E3/61 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 36 V stand-off voltage (VWM) and TA = 25 °C. This low leakage preserves signal integrity in high-impedance circuits such as precision sensor interfaces and battery-monitoring paths where microamp-level currents impact accuracy.
Does the SMA5J36CA-E3/61 require special handling or baking before reflow soldering?
No - the SMA5J36CA-E3/61 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be processed using standard lead-free reflow profiles with a maximum peak temperature of 260 °C without prior baking. This eliminates moisture sensitivity concerns and streamlines SMT production.
