Product details
Overview
SMA5J36C-E3/61 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 8.6 A peak pulse current (IPPM), and clamps to ≤58.1 V at rated surge. It is used in automotive sensor interfaces and industrial I/O protection where bidirectional transients occur.
For engineers reviewing the SMA5J36C-E3/61 datasheet, SMA5J36C-E3/61 pinout, SMA5J36C-E3/61 application, or SMA5J36C-E3/61 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both forward and reverse bias due to its bi-directional construction, enabling suppression of positive and negative polarity transients without polarity dependency. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance supports effective clamping under fast-rising 10/1000 µs surges.
The device is rated for continuous operation from −55 °C to +150 °C junction temperature and exhibits typical thermal resistance of 80 °C/W (junction-to-ambient) when mounted per recommended pad layout. It meets JESD201 Class 1A whisker test requirements and is qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse (or forward) voltage before clamping begins; defines operating margin for protected circuitry. |
| VBR (min/max) | 40.0 V / 44.2 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on across production lot. |
| IPPM | 8.6 A - Peak surge current it can safely divert under 10/1000 µs waveform; determines protection level against defined transient threats. |
| VC | ≤58.1 V - Clamped voltage at IPPM; must remain below protected IC's absolute maximum rating to prevent damage. |
| PPPM | 500 W - Peak pulse power handling capacity; defines energy absorption capability for standardized surge events. |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal derating envelope for sustained or repetitive surge conditions. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, bi-directional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); cathode band absent per bi-directional designation.

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-E3/61 | Identical electrical specs and packaging; CA suffix explicitly denotes bi-directional version per Vishay nomenclature - same as SMA5J36C-E3/61. | No functional difference; both intended for bi-directional line protection. | Select SMA5J36CA-E3/61 if ordering system requires explicit "CA" suffix for clarity in BOM traceability. |
| SMCJ36CA | Same VWM/VBR/VC, but higher PPPM = 1500 W and larger DO-214AB (SMC) package; RθJA = 20 °C/W vs. 80 °C/W. | Better suited for higher-energy surges (e.g., 4 kV ESD, 2 kA lightning) where PCB space allows larger footprint. | Choose SMCJ36CA only when surge threat level exceeds 500 W capability and thermal design accommodates lower power density. |
Compared with SMA5J36C-E3/61, SMA5J36CA-E3/61 is functionally identical and interchangeable, whereas SMCJ36CA offers higher surge capacity at the cost of board area and thermal performance - making SMA5J36C-E3/61 optimal for space-constrained, AEC-Q101-compliant designs requiring precise 500 W protection.

FAQ
What is the polarity configuration of SMA5J36C-E3/61?
SMA5J36C-E3/61 is a bi-directional TVS diode, meaning it has no designated anode or cathode - both terminals are functionally identical and provide symmetrical clamping for positive and negative transients. Unlike uni-directional variants, it carries no cathode band marking and is intended for AC or floating-line protection where polarity reversal may occur.
Is SMA5J36C-E3/61 qualified for automotive applications?
Yes, SMA5J36C-E3/61 is AEC-Q101 qualified and manufactured with RoHS-compliant matte tin terminations meeting JESD201 Class 1A whisker testing. Its −55 °C to +150 °C operating junction temperature range, glass-passivated junction, and MSL Level 1 rating make it suitable for under-hood and cabin-mounted automotive electronics including sensor interfaces and body control modules.
What is the maximum clamping voltage of SMA5J36C-E3/61 at rated surge current?
The maximum clamping voltage (VC) of SMA5J36C-E3/61 is 58.1 V, measured at its rated peak pulse current (IPPM) of 8.6 A under a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does SMA5J36C-E3/61 differ from SMA5J36A-E3/61?
SMA5J36C-E3/61 is bi-directional, while SMA5J36A-E3/61 is uni-directional. The "C" suffix indicates symmetrical clamping behavior and absence of polarity marking; the "A" suffix denotes cathode-banded construction for DC-biased lines. Their VWM, VBR, and PPPM ratings are identical, but SMA5J36A-E3/61 conducts forward surge current (IFSM = 40 A) and has different leakage behavior above VWM.
What PCB pad layout is recommended for optimal thermal performance of SMA5J36C-E3/61?
Vishay specifies mounting SMA5J36C-E3/61 on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 500 W pulse power and thermal resistance of 80 °C/W. Use minimum 2 oz copper with thermal vias beneath pads if ambient temperatures exceed 70 °C or surge repetition rate is high.
