Product details
Overview
SMA5J5.0CAHM3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.25 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), clamping voltage of 9.2 V at 54.3 A IPPM, and operates from –55 °C to +150 °C - used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J5.0CAHM3_A/H datasheet, SMA5J5.0CAHM3_A/H pinout, SMA5J5.0CAHM3_A/H application, or SMA5J5.0CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 500 W surge rating with 10/1000 μs waveform, low clamping ratio (VC/VBR ≈ 1.35), and halogen-free RoHS-compliant construction per ordering suffix HM3.
Technical Context
This device is a silicon avalanche diode engineered for unidirectional or bidirectional transient suppression using controlled reverse-biased breakdown. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<800 μA at VWM), while the low incremental surge resistance enables effective clamping during fast transients (response time <1 ns).
The SMA5J5.0CAHM3_A/H is rated for 500 W peak pulse power under 10/1000 μs waveform, with thermal resistance RθJA = 80 °C/W and RθJL = 25 °C/W. It meets MSL Level 1 (260 °C reflow) and is qualified to AEC-Q101 for automotive use - confirmed by HM3 suffix denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin. |
| VBR min/max | 6.4 V / 7.25 V - guaranteed breakdown range at 10 mA test current; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPPM | 9.2 V at 54.3 A - clamped voltage during 500 W surge; limits downstream IC stress to safe levels during ESD/EFT events. |
| PPPM | 500 W - peak pulse power handling with 10/1000 μs waveform; supports robust protection against inductive switching surges. |

Use Scenario: Input-stage protection for AC/DC adapters and USB-C PD controllers against lightning-induced surges on primary-side rectifier outputs. IC Role / Device Role / Timing Role: Secondary-side TVS on DC output rail to absorb repetitive switching transients and external ESD events. Use Value: Withstands >1000 surges at rated PPPM while maintaining VWM stability across 150 °C junction temperature. |
Use Scenario: Front-end protection for Ethernet PHYs and DSL line drivers subjected to induced surges per ITU-T K.20/K.44 standards. IC Role / Device Role / Timing Role: Bidirectional clamp on differential pairs to preserve common-mode rejection and signal timing integrity. Use Value: Low capacitance (<100 pF at zero bias) avoids signal distortion at 100 Mbps+ data rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0CAHE3_A/H | Same electrical specs and AEC-Q101 qualification, but RoHS-compliant without halogen-free requirement (E3 vs HM3). | Acceptable for commercial/industrial use where halogen-free is not mandated; not certified for automotive Tier-1 supply chains requiring HM3. | Select SMA5J5.0CAHE3_A/H when halogen-free content is not required and cost optimization is prioritized. |
| SMA6J5.0CAHM3_A/H | Higher PPPM rating (600 W vs 500 W); identical VWM, VBR, VC, and package; same AEC-Q101/HM3 compliance. | Better suited for systems requiring margin above 500 W surges (e.g., heavy-duty industrial motor drives or EV charging interfaces). | Choose SMA6J5.0CAHM3_A/H when design requires headroom beyond 500 W or future-proofing against higher surge standards. |
Compared with SMA5J5.0CAHM3_A/H, SMA5J5.0CAHE3_A/H offers identical protection performance without halogen-free assurance, while SMA6J5.0CAHM3_A/H delivers 20 % higher surge power handling in the same footprint - enabling direct layout reuse with enhanced robustness.

FAQ
What does the "HM3" suffix indicate in SMA5J5.0CAHM3_A/H?
The "HM3" suffix in SMA5J5.0CAHM3_A/H denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. It confirms compliance with automotive reliability standards and environmental regulations, distinguishing it from E3 (RoHS only) and HE3 (AEC-Q101 + RoHS, non-halogen-free) variants. This makes SMA5J5.0CAHM3_A/H suitable for Tier-1 automotive supply chains requiring strict material declarations.
Is SMA5J5.0CAHM3_A/H bidirectional, and how is polarity identified?
Yes, SMA5J5.0CAHM3_A/H is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional versions, it has no cathode band marking - the device functions identically regardless of orientation during PCB placement. This simplifies assembly and eliminates polarity verification steps in automated manufacturing.
What is the clamping voltage of SMA5J5.0CAHM3_A/H, and under what test condition is it specified?
The clamping voltage (VC) of SMA5J5.0CAHM3_A/H is 9.2 V, measured at a peak pulse current (IPPM) of 54.3 A using the standardized 10/1000 μs double-exponential surge waveform. This value reflects the maximum voltage seen across the device during a 500 W transient event, ensuring downstream circuitry remains within safe operating limits.
Can SMA5J5.0CAHM3_A/H replace SMA5J5.0A in an existing design?
No - SMA5J5.0CAHM3_A/H is bidirectional with 5.0 V stand-off, while SMA5J5.0A is unidirectional. Substituting them requires verifying circuit topology: SMA5J5.0CAHM3_A/H is appropriate for AC-coupled or differential lines, whereas SMA5J5.0A suits DC-biased single-ended paths. Also, SMA5J5.0CAHM3_A/H includes AEC-Q101 qualification and halogen-free materials not present in base SMA5J5.0A.
What thermal derating applies to SMA5J5.0CAHM3_A/H above 25 °C ambient?
SMA5J5.0CAHM3_A/H follows the derating curve in Figure 2 of its datasheet: peak pulse power decreases linearly from 100 % at 25 °C to ~50 % at 125 °C ambient. At 100 °C ambient, PPPM is reduced to approximately 70 % (350 W), based on RθJA = 80 °C/W. Layout with 0.2" × 0.2" copper pads per terminal is required to achieve published ratings.
