Product details
Overview
SMA5J36CHE3/61 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 power and signal lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤58.1 V at 8.6 A IPPM - used in automotive ECUs, industrial sensor interfaces, and telecom power rails.
For engineers reviewing the SMA5J36CHE3/61 datasheet, SMA5J36CHE3/61 pinout, SMA5J36CHE3/61 application, or SMA5J36CHE3/61 equivalent, key selection criteria include bi-directional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions, enabling robust protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the DO-214AC package delivers thermal resistance of 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead).
Designed for 10/1000 μs surge waveforms per IEC 61000-4-5, it achieves fast response time (<1.0 ps) and clamps voltage within nanoseconds of transient onset. The device is rated for non-repetitive peak pulse current up to 8.6 A and supports operation from –55 °C to +150 °C, meeting automotive-grade reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 40.0 V / 44.2 V at 1 mA - guaranteed breakdown threshold range for reliable triggering |
| VC @ IPPM | ≤58.1 V at 8.6 A - clamped voltage during 10/1000 μs surge, defining protected circuit stress level |
| PPPM | 500 W - peak transient energy absorption capability under standardized waveform |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
| TJ max | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Qualification | AEC-Q101 qualified - validated for automotive electronics reliability and lifetime performance |
Pinout & Package
DO-214AC (SMA) surface-mount package: molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C reflow peak), dimensions 4.93 mm × 3.99 mm × 2.29 mm (L × W × H). Bi-directional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |

| Case (body) | Thermal and mechanical interface | Non-electrical; provides mechanical mounting and contributes to thermal dissipation via PCB copper pads |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional architecture | Enables single-device protection of AC signals, differential buses, or ungrounded power rails without polarity concerns |
| Glass-passivated junction | Ensures tight VBR tolerance (±5%), long-term stability, and resistance to humidity-induced parameter drift |
| AEC-Q101 qualification | Validates performance across temperature cycling, mechanical shock, and high-temperature operating life for automotive deployment |
| Low Rsurge | Minimizes voltage overshoot during fast-rising transients by reducing dynamic impedance during clamping |
| MSL Level 1 rating | Supports standard lead-free reflow profiles without preconditioning, simplifying manufacturing integration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J36CA-E3/61 | Same electrical specs and DO-214AC package; differs only in RoHS-compliant commercial-grade marking (E3 vs HE3) | Lacks AEC-Q101 qualification; not approved for automotive under-hood use | Select SMA5J36CA-E3/61 only for cost-sensitive industrial or consumer designs where automotive qualification is unnecessary |
| SMCJ36CA | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VBR/VC specs | Requires larger PCB footprint and higher thermal mass; suited for higher-energy surge environments | Choose SMCJ36CA when system-level testing requires >500 W surge margin or when board layout allows larger package |
Compared with SMA5J36CHE3/61, SMA5J36CA-E3/61 offers identical protection performance but lacks automotive qualification, while SMCJ36CA delivers triple the surge power handling at the cost of increased size and thermal inertia - making SMA5J36CHE3/61 optimal for space-constrained AEC-Q101-compliant applications.

FAQ
What is the polarity configuration of SMA5J36CHE3/61?
The SMA5J36CHE3/61 is a bi-directional transient voltage suppressor, meaning it conducts equally in both forward and reverse directions. Unlike uni-directional variants, it has no cathode band marking and is intended for use on AC-coupled or floating lines where polarity is undefined. This configuration eliminates orientation errors during automated placement and simplifies design for differential or ungrounded signal paths.
Is SMA5J36CHE3/61 qualified for automotive applications?
Yes, SMA5J36CHE3/61 is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for under-hood and chassis-mounted automotive electronics where reliability under harsh conditions is mandatory.
What is the maximum clamping voltage of SMA5J36CHE3/61 during a surge event?
The SMA5J36CHE3/61 clamps to a maximum of 58.1 V at its rated peak pulse current (IPPM) of 8.6 A under a 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during standardized surge events, ensuring downstream components remain within safe operating voltage margins.
Does SMA5J36CHE3/61 require special PCB layout considerations?
Yes - for optimal thermal and electrical performance, SMA5J36CHE3/61 must be mounted on minimum recommended copper pads: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal, per Vishay's datasheet. Smaller pads increase thermal resistance and reduce surge current handling; inadequate copper may cause localized overheating or premature failure during repetitive transients.
How does the "HE3" suffix in SMA5J36CHE3/61 differ from "E3"?
The "HE3" suffix in SMA5J36CHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas "E3" indicates RoHS compliance only for commercial-grade use. Both share identical electrical parameters and DO-214AC packaging, but HE3 is certified for automotive applications requiring extended reliability validation.
