Product details
Overview
SMA5J5.0AHM3/I 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 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 interface protection.
For engineers reviewing the SMA5J5.0AHM3/I datasheet, SMA5J5.0AHM3/I pinout, SMA5J5.0AHM3/I application, or SMA5J5.0AHM3/I equivalent, key selection criteria include unidirectional polarity, halogen-free RoHS compliance, AEC-Q101 qualification, low incremental surge resistance, 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 optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its clamping behavior is defined by a controlled avalanche breakdown mechanism, with thermal resistance of 25 °C/W (junction-to-lead) enabling reliable energy dissipation during 8.3 ms half-sine surges up to 40 A (IFSM).
The SMA5J5.0AHM3/I is rated for bidirectional-capable families but is unidirectional (cathode-banded); its 500 W PPPM rating applies under standardized 10/1000 µs waveform conditions with derating above 25 °C ambient per Fig. 2, and it meets J-STD-020 MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin for protected line. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed avalanche initiation range; ensures predictable turn-on across production lot. |
| VC @ IPPM | 54.3 V at 9.2 A - clamped voltage during 500 W transient; defines worst-case stress on downstream ICs. |
| PPPM | 500 W (10/1000 µs) - peak transient energy handling capacity; validates suitability for ISO 7637-2 Pulse 1/2a/5a automotive tests. |
| TJ max | +150 °C - maximum junction temperature; supports under-hood automotive deployment with thermal design margin. |
| Polarity | Unidirectional - cathode marked with band; requires correct orientation in series with positive rail or signal path. |
| Package | SMA (DO-214AC) - surface-mount outline with 5.28 mm × 4.50 mm footprint; compatible with standard 7″ or 13″ tape-and-reel SMT feeders. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on one end.

Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting analog outputs of pressure/temperature sensors in engine bay environments exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VOUT and ground, clamping transients before they reach ADC input of microcontroller. Use Value: Limits induced voltage to ≤54.3 V during 500 W surges, preserving 12-bit ADC accuracy and preventing latch-up in 3.3 V/5 V signal chains. | Use Scenario: Safeguarding 24 V digital inputs on programmable logic controllers subjected to relay coil flyback and field wiring ESD. IC Role / Device Role / Timing Role: Primary protection device mounted at connector entry point, shunting surge energy away from optocoupler input stage. Use Value: Withstands 40 A non-repetitive forward surge (IFSM), enabling robust operation in factory automation where contactor switching dominates failure modes. |
| Consumer USB Power Line Protection | Telecom PoE Interface Protection |
Use Scenario: Guarding 5 V VBUS line in USB-C receptacles against hot-plug transients and cable discharge events. IC Role / Device Role / Timing Role: Standoff-rated TVS in series with VBUS, activated only during >6.4 V excursions to avoid interfering with normal 4.75–5.25 V regulation. Use Value: Clamps within <1 ns to limit stress on USB PD controller ICs; 800 µA leakage at 5 V ensures no impact on standby current budget. | Use Scenario: Secondary-level protection on powered device (PD) Ethernet ports receiving IEEE 802.3af/at power over twisted pair. IC Role / Device Role / Timing Role: DC rail protector on PSE-side 48 V input, placed after primary DC-DC converter but before PHY interface. Use Value: 500 W rating handles combined PoE surge + data-line coupling; DO-214AC footprint allows dense layout near RJ45 magnetics without thermal crowding. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0A-M3/61 | Same electrical specs, identical SMA package, but commercial-grade (non-AEC-Q101) and halogen-free RoHS only - no automotive qualification. | Lacks AEC-Q101 test validation; unsuitable for under-hood or safety-critical modules requiring automotive grade reliability. | Select when cost-sensitive industrial or consumer designs require halogen-free compliance without automotive certification. |
| 1.5SMC5.0A | Same VWM/VBR/PPPM ratings, but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher RθJA (60 °C/W vs. 80 °C/W) and different pad layout. | Requires PCB redesign due to larger footprint and 2.5× higher thermal mass; less suitable for space-constrained automotive modules. | Choose only if existing layout uses SMC or higher thermal mass is needed for sustained surge duty cycles. |
Compared with SMA5J5.0A-M3/61 and 1.5SMC5.0A, the SMA5J5.0AHM3/I uniquely combines AEC-Q101 qualification, halogen-free construction, and compact SMA packaging - making it the only option qualified for next-generation automotive sensor nodes where footprint, reliability, and regulatory compliance are jointly constrained.

FAQ
What is the clamping voltage of the SMA5J5.0AHM3/I at its rated peak pulse current?
The SMA5J5.0AHM3/I has a maximum clamping voltage (VC) of 54.3 V at its specified peak pulse current (IPPM) of 9.2 A under the 10/1000 µs waveform condition. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during a 500 W transient event. The SMA5J5.0AHM3/I maintains this clamping performance across its qualified temperature range (–55 °C to +150 °C) with appropriate derating above 25 °C ambient.
Is the SMA5J5.0AHM3/I suitable for automotive applications?
Yes, the SMA5J5.0AHM3/I is AEC-Q101 qualified and explicitly designated for automotive use via its HM3 suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling, and human-body-model ESD ≥ 8 kV. The SMA5J5.0AHM3/I is deployed in engine control units, ADAS camera modules, and body electronics where protection against load dump, jump-start, and ISO 7637-2 pulses is required.
How does the SMA5J5.0AHM3/I differ from the SMA5J5.0A-E3/61 variant?
The SMA5J5.0AHM3/I differs from SMA5J5.0A-E3/61 in three key ways: it carries the HM3 suffix indicating halogen-free + AEC-Q101 qualification (vs. E3's commercial RoHS-only status), uses revision code "I" denoting a specific manufacturing lot traceability and process control level, and ships in 13″ tape-and-reel (7500 pcs) rather than 7″ (1800 pcs). Electrically and physically, both share identical VWM, VBR, PPPM, and SMA package dimensions.
What is the maximum reverse leakage current of the SMA5J5.0AHM3/I at its stand-off voltage?
The SMA5J5.0AHM3/I exhibits a maximum reverse leakage current (ID) of 800 µA at its 5.0 V stand-off voltage (VWM), measured at 25 °C ambient. This low leakage ensures minimal impact on battery-powered or low-quiescent-current systems - for example, it contributes less than 0.1 % error in a 5 V rail monitoring circuit using a 10 MΩ divider. Leakage increases with temperature but remains below 2 mA up to TJ = 125 °C per characterization curves.
Can the SMA5J5.0AHM3/I be used in bidirectional protection circuits?
No, the SMA5J5.0AHM3/I is a unidirectional TVS diode, as confirmed by its part number suffix "A" (not "CA") and cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., SMA5J5.0CA), which lacks polarity marking and conducts symmetrically in both directions. Using SMA5J5.0AHM3/I in a bidirectional configuration would result in forward conduction during negative transients, potentially damaging the device or failing to protect downstream components.
