Product details
Overview
SMA5J5.0AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 µs), 54.3 V clamping voltage at 9.2 A peak current, and operates from –55 °C to +150 °C - used in automotive sensor power rail protection.
For engineers reviewing the SMA5J5.0AHM3_A/H datasheet, SMA5J5.0AHM3_A/H pinout, SMA5J5.0AHM3_A/H application, or SMA5J5.0AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 80 °C/W), and clamping performance under IEC 61000-4-5 surge conditions.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked.
The SMA5J5.0AHM3_A/H is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), supports automated SMT placement, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-volume automotive and industrial PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; sets minimum system operating margin. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - defines guaranteed breakdown threshold range for design margining and tolerance stack-up. |
| VC @ IPPM | 54.3 V at 9.2 A - clamping voltage during 10/1000 µs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 500 W - peak pulse power handling capability; defines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| RθJA | 80 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs board-level thermal design. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line (e.g., GND or return path). |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to higher-potential side (e.g., +5 V rail); conducts only during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan. |
| Halogen-free & RoHS-compliant | Meets JEDEC JS709E and IPC-1752A requirements; supports green manufacturing and end-of-life recycling. |
| MSL Level 1 (260 °C) | Enables single-pass lead-free reflow without moisture sensitivity concerns or baking requirements. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving protection fidelity. |
Applications
| Automotive Sensor Power Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 5 V supply lines feeding Hall-effect or temperature sensors in engine control modules. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between VCC and GND to shunt load dump and inductive switching transients. Use Value: Clamps 500 W surges to ≤54.3 V while maintaining <800 µA leakage at 5.0 V - preserving sensor accuracy and MCU reset integrity. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to 24 V field wiring. IC Role / Device Role / Timing Role: Standoff-rated TVS on input front-end to absorb induced lightning surges and relay coil flyback. Use Value: Withstands 40 A 8.3 ms forward surge and maintains 5.0 V standoff - enabling direct interface with optocoupler input stages without series resistance. |
| Consumer USB Port ESD Suppression | Telecom DC Power Feed Protection |
Use Scenario: Secondary-level surge protection on 5 V USB VBUS lines in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Downstream TVS after primary fuse and upstream polymer PTC, providing final clamping layer. Use Value: 54.3 V clamping ensures downstream USB PHY ICs (e.g., USB 2.0 transceivers) remain below absolute maximum ratings during 1 kV/0.5 µs transients. |
Use Scenario: Protecting -48 V telecom power feeds entering remote radio units and base station cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS configured anode-to-rail to clamp positive-going surges on negative supply systems. Use Value: 6.4–7.07 V VBR allows use with biasing networks to adapt to -48 V systems via resistor-divider referencing - verified in Vishay AN1007. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0AHE3_A/H | Same electrical specs, but RoHS-compliant without halogen-free certification; no JESD201 Class 2 whisker test. | Approved for commercial-grade automotive modules not requiring halogen-free compliance (e.g., infotainment). | Select when halogen-free material declaration is not mandated by OEM specification. |
| SMA5J5.0A-M3/61 | Identical electrical and thermal specs; differs only in packaging format (61 reel code vs. A/H) and base quantity (1800 pcs). | No functional difference; intended for different logistics and inventory management workflows. | Choose based on production volume planning and tape-and-reel procurement alignment. |
Compared with SMA5J5.0AHM3_A/H, the HE3 variant lacks halogen-free validation and whisker resistance, while the M3/61 shares full electrical equivalence but omits AEC-Q101 qualification - making SMA5J5.0AHM3_A/H the sole choice for Tier-1 automotive power rail designs requiring both halogen-free and AEC-Q101 compliance.

FAQ
What is the AEC-Q101 qualification status of SMA5J5.0AHM3_A/H?
SMA5J5.0AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 88875 (Revision 09-Jan-2024). This qualification covers stress tests including HTGB, HTRB, TCT, and ESD per AEC-Q101-001 Rev D, validating its use in automotive powertrain and chassis modules.
Does SMA5J5.0AHM3_A/H have halogen-free construction?
Yes, SMA5J5.0AHM3_A/H is halogen-free and RoHS-compliant, per Vishay's material categorization and ordering code "HM3". It meets JEDEC JS709E and IPC-1752A standards, with bromine, chlorine, and other halogens below detection limits - required for Tier-1 automotive supply chain compliance.
What is the maximum clamping voltage for SMA5J5.0AHM3_A/H under surge conditions?
The maximum clamping voltage VC for SMA5J5.0AHM3_A/H is 54.3 V at 9.2 A peak pulse current (IPPM), measured with a 10/1000 µs waveform per Figure 1 in datasheet 88875. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can SMA5J5.0AHM3_A/H be used in bidirectional configurations?
No, SMA5J5.0AHM3_A/H is unidirectional only, as indicated by the "A" suffix (not "CA") and cathode band marking. Bidirectional variants such as SMA5J5.0CA exist but differ electrically - using SMA5J5.0AHM3_A/H in bidirectional applications would result in forward conduction during negative transients and potential failure.
What is the thermal resistance junction-to-ambient for SMA5J5.0AHM3_A/H?
The typical thermal resistance junction-to-ambient (RθJA) for SMA5J5.0AHM3_A/H is 80 °C/W, measured on a standard PCB layout with 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes no additional heatsinking and guides thermal derating above TA = 25 °C per Figure 2 in the datasheet.
