Product details
Overview
SMA5J6.0CAHM3/I from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J6.0CAHM3/I datasheet, SMA5J6.0CAHM3/I pinout, SMA5J6.0CAHM3/I application, or SMA5J6.0CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (via HM3 suffix), 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR and low leakage (<1.0 µA at VWM), while the low RθJA of 80 °C/W supports thermal reliability under repeated surge events.
The SMA5J6.0CAHM3/I complies with ANSI/IEEE C62.35 for transient suppression and meets JESD201 Class 2 whisker resistance. Its halogen-free, RoHS-compliant HM3 suffix confirms suitability for automotive-grade production per AEC-Q101, with MSL Level 1 rating and 260 °C lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range defining turn-on consistency |
| VC @ IPPM | ≤10.3 V at 48.5 A - Clamped voltage during full-rated 10/1000 µs surge, limiting stress on downstream ICs |
| PPPM | 500 W - Peak transient energy handling capacity under standardized waveform, critical for load-switching immunity |
| ID @ VWM | ≤1.0 µA - Ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +150 °C - Enables operation in under-hood automotive or industrial ambient environments without derating |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.

Use Value: Limits let-through voltage to PHY ICs rated for ≤12 V absolute maximum, extending mean time between failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0CAHE3/I | RoHS-compliant but not halogen-free; AEC-Q101 qualified (HE3 suffix); identical electrical specs | Approved for automotive use but lacks halogen-free certification required by some Tier 1 OEMs | Select when halogen content is unrestricted and cost optimization is prioritized over material compliance tiers |
| SMA6J6.0CAHM3/I | 600 W PPPM rating (vs. 500 W); same VWM/VBR/VC; larger thermal mass due to SMA6J package (DO-214AB) | Used where higher single-pulse energy tolerance is needed, e.g., heavy-duty industrial motor controls | Select only if board layout accommodates DO-214AB footprint and 600 W surge margin is explicitly required |
Compared with SMA5J6.0CAHM3/I, SMA5J6.0CAHE3/I offers identical protection performance with lower material compliance scope, while SMA6J6.0CAHM3/I increases surge capacity at the cost of footprint and thermal coupling - making the original optimal for space-constrained AEC-Q101 designs needing precise 500 W handling.

FAQ
What does the "HM3" suffix indicate in SMA5J6.0CAHM3/I?
The "HM3" suffix in SMA5J6.0CAHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms the device meets automotive reliability standards, uses environmentally compliant materials, and is rated for reflow up to 260 °C. This distinguishes SMA5J6.0CAHM3/I from commercial-grade variants like SMA5J6.0CA-E3 and ensures suitability for under-hood and safety-critical vehicle subsystems.
Is SMA5J6.0CAHM3/I unidirectional or bidirectional?
SMA5J6.0CAHM3/I is a bidirectional Transient Voltage Suppressor, as indicated by the "CA" in its part number. It provides symmetrical clamping for both positive and negative transients without polarity dependence, making it ideal for AC-coupled lines, differential buses, or floating grounds where voltage reversals occur. Unlike unidirectional variants (e.g., SMA5J6.0A), SMA5J6.0CAHM3/I has no cathode marking and identical VBR in both directions.
What is the maximum clamping voltage of SMA5J6.0CAHM3/I under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.0CAHM3/I is 10.3 V at its rated peak pulse current (IPPM) of 48.5 A, tested with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case transients. It ensures compatibility with 12 V tolerant ICs and prevents overvoltage damage in sensitive analog or digital interfaces.
Does SMA5J6.0CAHM3/I require a heatsink for standard operation?
No, SMA5J6.0CAHM3/I does not require an external heatsink under typical surge duty cycles. Its thermal resistance (RθJA) is 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, sufficient for dissipating 500 W peak pulses of short duration. Continuous power dissipation is not applicable, as TVS devices operate only during transient events - sustained heating is negligible in normal operation.
How does SMA5J6.0CAHM3/I compare to SMA5J6.0A in terms of application use?
SMA5J6.0CAHM3/I is bidirectional and AEC-Q101/halogen-free qualified, whereas SMA5J6.0A is unidirectional and commercial-grade (E3/M3). SMA5J6.0CAHM3/I suits automotive sensor lines and floating interfaces needing polarity-agnostic protection; SMA5J6.0A fits DC power rails or grounded signal paths where only one polarity surge matters. Their VWM, VBR, and VC values differ slightly due to bidirectional design constraints - SMA5J6.0CAHM3/I maintains 6.0 V VWM but with symmetric clamping, unlike SMA5J6.0A's cathode-referenced behavior.
