Product details
Overview
SMA5J36CAHE3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 36 V standoff voltage (VWM), 40.0–44.2 V breakdown (VBR), 500 W peak pulse power (PPPM), and clamping to ≤58.1 V at 8.6 A IPPM. It protects signal lines and power rails in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the SMA5J36CAHE3/61 datasheet, SMA5J36CAHE3/61 pinout, SMA5J36CAHE3/61 application, or SMA5J36CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 500 W surge rating with 10/1000 µs waveform, low thermal resistance (RθJL = 25 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with clamping voltage VC ≤ 58.1 V at IPPM = 8.6 A under 10/1000 µs surge conditions and reverse leakage ID ≤ 1.0 µA at VWM = 36 V. Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device is AEC-Q101 qualified (HE3 suffix), enabling use in automotive ECUs and ADAS sensor interfaces. Thermal performance is defined by RθJA = 80 °C/W (typ.) and RθJL = 25 °C/W (typ.), allowing reliable operation up to TJ = +150 °C with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail. |
| VBR min/max | 40.0 V / 44.2 V - Verified breakdown range at 1 mA test current; guarantees consistent turn-on across production lot. |
| VC @ IPPM | ≤58.1 V at 8.6 A - Clamped voltage during 10/1000 µs surge; determines protected IC's maximum stress level. |
| PPPM | 500 W - Peak pulse power handling per single transient; defines robustness against lightning or load dump events. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at standoff voltage; ensures minimal standby power loss in battery-powered systems. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; supports high-reliability solder joint integrity during surge events. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Case meets UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional terminal pair | No polarity marking; identical clamping behavior in either direction - simplifies layout and eliminates orientation errors. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control and ADAS modules. |
| 500 W peak pulse power (10/1000 µs) | Withstands high-energy transients from inductive loads (e.g., solenoids, motors) without degradation over rated lifetime. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream ICs - critical for protecting 3.3 V or 5 V logic interfaces in sensor signal chains. |
| MSL Level 1, 260 °C peak reflow | Enables standard lead-free SMT assembly without pre-baking or special handling - reduces manufacturing cost and risk. |
| Glass-passivated junction | Ensures stable VBR over time and temperature, low leakage, and immunity to humidity-induced parameter drift. |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and microcontroller I/O pins in vehicle door modules and body control units from load dump and ESD. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching PHY layer. Use Value: Maintains signal integrity under ISO 7637-2 Pulse 1/2/5a stress while meeting AEC-Q101 requirements for 15-year field life. |
Use Scenario: Safeguarding differential CANH/CANL lines in factory automation gateways exposed to motor drive noise and relay switching. IC Role / Device Role / Timing Role: Low-capacitance TVS pair (one per line) suppressing common-mode surges without distorting 1 Mbps CAN signaling. Use Value: Clamps to ≤58.1 V while adding <1 pF parasitic capacitance - preserves bus timing margins and bit error rate. |
| Consumer Power Adapter Input | Telecom PoE Data Line Protection |
Use Scenario: Secondary-side DC input protection in USB-C PD adapters against reverse polarity misconnection and hot-swap surges. IC Role / Device Role / Timing Role: Bidirectional clamp between VBUS and GND, placed after primary-side isolation but before DC-DC controller. Use Value: Withstands 500 W surges without latch-up or parametric shift - avoids field returns due to adapter failure during plug insertion. |
Use Scenario: Protecting Ethernet PHY magnetics and data pairs in IEEE 802.3af/at PoE injectors/splitters from induced lightning surges. IC Role / Device Role / Timing Role: Common-mode TVS across differential pairs (e.g., TX+/TX−, RX+/RX−) referenced to chassis ground. Use Value: Symmetric clamping ensures balanced suppression on both lines - prevents data skew and maintains 100BASE-TX eye diagram compliance. |
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 | Same electrical specs; halogen-free, RoHS-compliant, commercial grade (not AEC-Q101 qualified). | Lacks automotive qualification - suitable for industrial/commercial equipment where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle traceability is not needed. |
| SMA6J36CAHE3/61 | 600 W PPPM rating (vs. 500 W); otherwise identical VWM, VBR, VC, and package; same AEC-Q101 qualification. | Higher surge margin allows extended lifetime in high-noise environments (e.g., heavy-duty vehicle alternators). | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or ISO 7637-2 Test 5b demands extra headroom. |

FAQ
What is the clamping voltage of the SMA5J36CAHE3/61 under a 10/1000 µs surge?
The SMA5J36CAHE3/61 clamps to a maximum of 58.1 V when subjected to its rated peak pulse current of 8.6 A using the standardized 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads) and is guaranteed across the full operating temperature range.
Is the SMA5J36CAHE3/61 suitable for automotive applications?
Yes, the SMA5J36CAHE3/61 is AEC-Q101 qualified, as indicated by the "HE3" suffix. It has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per AEC-Q101 Rev D, making it suitable for under-hood and cabin applications such as body control modules, ADAS sensors, and infotainment power supplies.
Does the SMA5J36CAHE3/61 have polarity markings?
No, the SMA5J36CAHE3/61 is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction provides identical clamping characteristics in both directions, eliminating orientation concerns during automated placement and simplifying PCB layout.
What is the maximum junction temperature rating for the SMA5J36CAHE3/61?
The SMA5J36CAHE3/61 has a maximum junction temperature (TJ max) of +150 °C, as specified in the Vishay datasheet. This rating enables reliable operation in high-ambient environments such as automotive engine compartments or industrial motor drives when implemented with adequate PCB copper area per the recommended pad layout.
How does the SMA5J36CAHE3/61 differ from the unidirectional SMA5J36AHE3/61?
The SMA5J36CAHE3/61 is bidirectional with symmetrical clamping, while the SMA5J36AHE3/61 is unidirectional and features a cathode band marking. Electrically, the unidirectional version supports forward surge current (IFSM = 40 A) and has VF = 3.5 V at 25 A - capabilities absent in the bidirectional CA variant, which is optimized for AC or differential line protection.
