Product details
Overview
SMA5J5.0A-E3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 54.3 V clamping voltage at 9.2 A peak pulse current, and operates from –55 °C to +150 °C junction temperature - used in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMA5J5.0A-E3/61 datasheet, SMA5J5.0A-E3/61 pinout, SMA5J5.0A-E3/61 application, or SMA5J5.0A-E3/61 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity marking, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability (VF = 3.5 V at 25 A) and reverse-biased clamping action during transients.
The device is rated for 500 W peak pulse power per 10/1000 µs waveform, derated above 25 °C with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 5 V systems. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed breakdown range ensures reliable turn-on during ESD or load-dump events. |
| VC @ IPPM | 54.3 V at 9.2 A - clamping voltage limits protected circuit stress during 500 W transient surges. |
| PPPM | 500 W (10/1000 µs) - peak surge energy handling capacity for automotive ISO 7637-2 Pulse 1/2a/5a compliance. |
| IFSM | 40 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during inductive switch-off. |
| TJ max | +150 °C - enables operation in under-hood automotive environments and high-power industrial enclosures. |
| Package | SMA (DO-214AC) - surface-mount outline with cathode band marking; compatible with standard 7" tape-and-reel (E3/61). |
Pinout & Package
SMA (DO-214AC) package: molded epoxy case meeting UL 94 V-0, matte tin-plated leads solderable per J-STD-002, polarity indicated by cathode band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Reverse-biased terminal / clamping node | Connected to protected line (e.g., 5 V rail); conducts during overvoltage to shunt surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Low profile SMA package | Height ≤ 2.29 mm - enables compact PCB layout in space-constrained automotive modules and IoT edge nodes. |
| Glass passivated junction | Stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Reflow-compatible up to 260 °C peak - supports single-pass lead-free assembly without moisture sensitivity concerns. |
| AEC-Q101 qualification option | HE3/HM3 variants available - meets automotive-grade stress test requirements for engine control and ADAS subsystems. |
| 500 W surge capability | Clamps 9.2 A transient at ≤54.3 V - protects downstream 5 V logic ICs, CAN transceivers, and microcontroller I/O pins. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Lower PPPM (400 W), higher VC (9.6 V at 7.5 A), same VWM/VBR range and SMA package. | Less robust for ISO 7637-2 Pulse 5a; suitable for lower-energy ESD-only scenarios. | Select SMAJ5.0A only if system-level surge testing confirms 400 W sufficiency and layout allows tighter thermal management. |
| 1.5SMC5.0A | Higher package thermal mass (SMC/DO-214AB), same electrical specs but RθJA = 40 °C/W and PPPM = 1500 W. | Overqualified for space-constrained designs; requires larger PCB footprint and different tape/reel logistics. | Choose 1.5SMC5.0A only when sustained surge duty cycle or ambient >85 °C demands superior thermal dissipation. |
Compared with SMAJ5.0A and 1.5SMC5.0A, the SMA5J5.0A-E3/61 delivers optimal balance of 500 W surge capacity, SMA footprint, and RoHS-compliant E3 termination - making it preferred for high-volume automotive and industrial SMT production where board area and reflow compatibility are critical.

FAQ
What is the clamping voltage of the SMA5J5.0A-E3/61 under maximum rated surge current?
The SMA5J5.0A-E3/61 has a maximum clamping voltage (VC) of 54.3 V at its rated peak pulse current (IPPM) of 9.2 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The SMA5J5.0A-E3/61 maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction design.
Is the SMA5J5.0A-E3/61 suitable for automotive applications?
Yes - while the base SMA5J5.0A-E3/61 is commercial-grade, it shares identical electrical and mechanical specifications with the AEC-Q101-qualified variant SMA5J5.0AHE3_A/H. Its MSL Level 1 rating, JESD201 Class 2 whisker resistance, and operation up to +150 °C junction temperature make it suitable for under-hood and cabin applications when validated per system-level requirements. The SMA5J5.0A-E3/61 is widely deployed in automotive body control modules and infotainment power supplies.
How does the SMA5J5.0A-E3/61 differ from the SMAJ5.0A in practical design use?
The SMA5J5.0A-E3/61 offers 25 % higher peak pulse power (500 W vs. 400 W) and lower clamping voltage (54.3 V vs. 9.6 V at respective IPPM) than the SMAJ5.0A, enabling more robust protection against ISO 7637-2 Pulse 5a load-dump events. Both use SMA (DO-214AC) packages and share VWM/VBR specs, but the SMA5J5.0A-E3/61's improved surge margin reduces risk of downstream IC latch-up in 5 V rail protection. The SMA5J5.0A-E3/61 also features enhanced thermal resistance derating curves for sustained surge duty cycles.
What is the meaning of the "-E3/61" suffix in SMA5J5.0A-E3/61?
The "-E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 mechanical reliability standards. The "/61" denotes the preferred packaging code: 7-inch diameter plastic tape-and-reel containing 1800 units, optimized for high-speed pick-and-place equipment. This packaging format ensures consistent feed performance and traceability for automated SMT lines using the SMA5J5.0A-E3/61.
Does the SMA5J5.0A-E3/61 require heatsinking for standard operation?
No additional heatsinking is required for single-event transient suppression under typical conditions, as the SMA5J5.0A-E3/61 is rated for 500 W peak power with thermal resistance RθJA = 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. However, for repetitive surge events or ambient temperatures exceeding 75 °C, PCB copper area should be maximized per Vishay's recommended pad layout (Document 88875, page 4). The SMA5J5.0A-E3/61 relies on board-level thermal conduction rather than external heatsinks.
