Product details
Overview
SMA5J6.0CAHM3/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 a 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), clamping voltage of 10.3 V at 48.5 A, and operates from –55 °C to +150 °C junction temperature.
For engineers reviewing the SMA5J6.0CAHM3/H datasheet, SMA5J6.0CAHM3/H pinout, SMA5J6.0CAHM3/H application, or SMA5J6.0CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification (via HM3 suffix), halogen-free RoHS compliance, and suitability for automotive sensor line and industrial I/O port protection where fast response (<1 ns), low clamping ratio, and MSL Level 1 reflow compatibility are required.
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 leakage and repeatable clamping performance under repetitive surge stress.
Rated for 500 W peak pulse power with 10/1000 µs waveform, it delivers 48.5 A peak surge current and clamps to ≤10.3 V-critical for protecting 5 V–6 V logic interfaces and automotive CAN/LIN transceivers without overvoltage damage. Thermal resistance is 80 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line's nominal DC bias. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable triggering above VWM with margin against false conduction. |
| VC @ IPPM | 10.3 V at 48.5 A - Clamping voltage during full-rated 500 W surge; guarantees downstream ICs see <11 V under worst-case transients. |
| PPPM | 500 W - Peak pulse power handling per 10/1000 µs waveform; enables robust protection against ISO 7637-2 Pulse 1/2/5a/b and IEC 61000-4-5 surges. |
| TJ max | +150 °C - Maximum junction temperature supports operation in under-hood automotive environments and industrial enclosures. |
| Package | SMA (DO-214AC) - Surface-mount package with 2.54 mm lead pitch; compatible with automated placement and reflow up to 260 °C peak. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 compliant. Bidirectional construction means no polarity marking; both terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically in either direction during overvoltage events; no cathode band marking required for bidirectional types. |

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/H | Same electrical specs and package, but RoHS-compliant commercial grade (not AEC-Q101 qualified); uses E3 suffix instead of HM3. | Lacks automotive qualification; suitable for consumer, computing, and non-safety-critical industrial use only. | Select when AEC-Q101 is not required and halogen-free content is not mandated. |
| SMBJ6.0CA-M3 | Same VWM/VBR/VC, but SMB (DO-214AA) package-larger footprint (4.58 mm × 3.94 mm vs. SMA's 4.50 mm × 2.79 mm) and higher PPPM (600 W). | Offers higher surge margin but requires PCB layout change; better for high-reliability industrial power supply inputs. | Choose when board space allows larger package and higher 600 W surge rating is needed for harsher environments. |
Compared with SMA5J6.0CAHE3/H, the SMA5J6.0CAHM3/H adds AEC-Q101 qualification and halogen-free construction-essential for automotive Tier 1 suppliers-while SMBJ6.0CA-M3 trades compactness for higher power handling, making it preferable where layout permits and 100 W extra surge capacity improves system-level immunity margin.

FAQ
What does the "HM3" suffix indicate in SMA5J6.0CAHM3/H?
The "HM3" suffix in SMA5J6.0CAHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms the device meets automotive reliability standards-including temperature cycling, highly accelerated life testing, and ESD robustness-while eliminating brominated flame retardants per JEDEC J-STD-020 and IEC 61249-2-21.
Is SMA5J6.0CAHM3/H suitable for protecting CAN bus lines?
Yes, SMA5J6.0CAHM3/H is well-suited for CAN FD and classical CAN bus protection. Its 6.0 V VWM aligns with typical 5 V CAN transceiver common-mode range, bidirectional clamping handles differential and common-mode transients, and 10.3 V clamping voltage stays safely below the 16 V absolute maximum rating of most CAN PHYs-preserving signal integrity and fault tolerance.
How does SMA5J6.0CAHM3/H differ from unidirectional SMA5J6.0A variants?
SMA5J6.0CAHM3/H is bidirectional with symmetrical clamping in both polarities and no cathode marking, whereas SMA5J6.0A is unidirectional with a cathode band and conducts only in reverse bias. This makes SMA5J6.0CAHM3/H ideal for AC-coupled or differential lines like RS-485 or Ethernet PHYs, while SMA5J6.0A suits DC power rail protection where polarity is fixed.
What is the maximum PCB pad size recommended for optimal thermal performance of SMA5J6.0CAHM3/H?
Vishay specifies that SMA5J6.0CAHM3/H achieves its rated 500 W peak pulse power when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Smaller pads reduce thermal dissipation and derate surge capability-e.g., 2.5 mm × 2.5 mm pads may limit IPPM to ~35 A instead of 48.5 A. Always follow the recommended pad layout in the DO-214AC outline drawing.
Does SMA5J6.0CAHM3/H meet any specific industry surge immunity standards out of the box?
SMA5J6.0CAHM3/H is characterized to handle standardized surge waveforms including 10/1000 µs (IEC 61000-4-5) and 8.3 ms half-sine (IEC 61000-4-4 EFT), but system-level compliance depends on PCB layout, coordination with upstream protectors (e.g., GDTs), and filtering. Its 500 W rating and 10.3 V clamping make it a proven first-stage element in designs meeting ISO 16750-2 (automotive) and IEC 61000-4-5 Level 3–4 (industrial).
