Product details
Overview
SMA5J5.0A-E3/5A 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 sensor power rail protection.
For engineers reviewing the SMA5J5.0A-E3/5A datasheet, SMA5J5.0A-E3/5A pinout, SMA5J5.0A-E3/5A application, or SMA5J5.0A-E3/5A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, unidirectional polarity marking, RoHS-compliant matte tin plating, MSL Level 1 reflow compatibility, and AEC-Q101 qualification path via HE3 suffix variants.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its unidirectional configuration provides forward conduction capability with 3.5 V forward voltage at 25 A, while maintaining tight VBR tolerance (±5 % typical) and low leakage (<800 µA at VWM).
The device is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), derated above 25 °C per Fig. 2, and exhibits thermal resistance of 80 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads. Polarity is marked by cathode band; no marking on bidirectional versions.
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 |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - ensures reliable turn-on during overvoltage events without premature conduction |
| VC @ IPPM | 54.3 V at 9.2 A - clamping voltage limits downstream IC stress during 10/1000 µs surge |
| PPPM | 500 W - peak pulse power handling capacity for standardized transient immunity compliance testing |
| IFSM | 40 A - single half-sine surge rating supports inrush and load-dump scenarios in automotive power systems |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |

|---|---|
Use Scenario: Protecting 5 V supply rails of engine control unit (ECU) pressure sensors against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor VDD and chassis ground to shunt transient energy before reaching ASIC. Use Value: Limits clamped voltage to ≤54.3 V, preventing damage to 36 V-rated sensor front-end circuitry during 100 V/100 ms load dump events. |
Use Scenario: Safeguarding 24 V digital input channels of programmable logic controllers against field-wiring induced surges and EFT bursts. IC Role / Device Role / Timing Role: Primary protection device mounted at connector entry point, upstream of series resistor and optocoupler. Use Value: Responds in <1 ns to suppress 1 kV/50 Ω ring wave transients to safe levels within 10/1000 µs waveform envelope. |
| Consumer USB Port ESD Protection | Telecom Line Interface Surge Suppression |
Use Scenario: Secondary-level protection for 5 V USB VBUS lines in set-top boxes and smart displays exposed to human-body-model (HBM) ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after fuse and upstream of USB controller's internal protection diodes. Use Value: Clamps 8 kV HBM ESD events to <54.3 V, reducing stress on integrated 5 V tolerant I/O structures. |
Use Scenario: DC feed protection for PoE-powered Ethernet switches where 48 V bias lines are susceptible to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Unidirectional clamp on each DC feed leg referenced to local ground plane in midspan injector design. Use Value: Handles 500 W peak surge without degradation, maintaining 5.0 V standoff to avoid false triggering during normal 48 V operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/61 | Lower PPPM (400 W vs. 500 W); same VWM/VBR range and SMA package | Less robust for high-energy 10/1000 µs surges; suitable for cost-sensitive consumer designs with lower immunity requirements | Select when 400 W surge rating suffices and tape-and-reel quantity (1800 pcs) aligns with production volume |
| SMBJ5.0A-E3/52 | Higher PPPM (600 W); SMB (DO-214AA) package - 2.6 mm wider body, same pin spacing | Requires PCB footprint change; preferred for industrial applications demanding higher surge margin and thermal mass | Choose when board space allows larger package and 600 W rating is required for IEC 61000-4-5 Level 4 compliance |
Compared with SMAJ5.0A-E3/61 and SMBJ5.0A-E3/52, the SMA5J5.0A-E3/5A delivers optimal balance of 500 W surge capacity, compact SMA footprint, and 7500-piece tape-and-reel packaging - making it ideal for automotive-tier-2 suppliers requiring AEC-Q101-ready variants and high-volume SMT throughput.

FAQ
What is the clamping voltage of the SMA5J5.0A-E3/5A under standard 10/1000 µs surge conditions?
The SMA5J5.0A-E3/5A has a maximum clamping voltage (VC) of 54.3 V at 9.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C with the device mounted on 5.0 mm × 5.0 mm copper pads per JEDEC test conditions, ensuring repeatable surge immunity validation for system-level compliance testing.
Is the SMA5J5.0A-E3/5A RoHS-compliant and halogen-free?
Yes, the SMA5J5.0A-E3/5A carries the "E3" suffix, indicating it is RoHS-compliant and meets commercial-grade environmental specifications. It is not halogen-free; for halogen-free and RoHS-compliant versions, select the "M3" suffix variant (e.g., SMA5J5.0A-M3/5A), which also satisfies JESD201 Class 2 whisker resistance requirements.
Does the SMA5J5.0A-E3/5A have AEC-Q101 qualification?
The base SMA5J5.0A-E3/5A is not AEC-Q101 qualified. However, Vishay offers automotive-grade versions under ordering codes SMA5J5.0AHE3_A/H and SMA5J5.0AHM3_A/H - both explicitly qualified to AEC-Q101 and marked with "HE3" (RoHS + AEC-Q101) or "HM3" (halogen-free + RoHS + AEC-Q101) suffixes.
What is the thermal resistance of the SMA5J5.0A-E3/5A, and how does it affect layout?
The SMA5J5.0A-E3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per specification. To maintain safe operation under repeated surges, PCB layout must provide adequate copper area and thermal vias - reducing RθJA improves sustained surge handling and prevents thermal runaway during multi-pulse events.
How is polarity identified on the SMA5J5.0A-E3/5A package?
Polarity on the SMA5J5.0A-E3/5A is indicated by a visible cathode band at one end of the SMA (DO-214AC) package. The banded end corresponds to the cathode terminal, which must be connected toward the higher-potential side of the protected line (e.g., VCC or signal source), while the unmarked end is the anode, connected toward ground or return path.
