Product details
Overview
SMA5J6.0CAHM3_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 a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 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 where bidirectional overvoltage transients occur.
For engineers reviewing the SMA5J6.0CAHM3_A/H datasheet, SMA5J6.0CAHM3_A/H pinout, SMA5J6.0CAHM3_A/H application, or SMA5J6.0CAHM3_A/H equivalent, key selection criteria include bidirectional polarity, 500 W surge rating, 10.3 V clamping voltage at 48.5 A, AEC-Q101 qualification status, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both directions, enabling robust suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while MSL Level 1 rating supports lead-free reflow compatibility up to 260 °C peak.
The SMA5J6.0CAHM3_A/H delivers 500 W peak pulse power under standardized 10/1000 µs waveform conditions when mounted on 5.0 mm × 5.0 mm copper pads. Its thermal resistance (RθJA = 80 °C/W) and 150 °C maximum junction temperature support reliable operation in compact, thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤10.3 V at 48.5 A - Clamping voltage under full-rated 500 W surge; determines protected circuit's maximum stress level. |
| PPPM | 500 W - Peak pulse power handling capability with 10/1000 µs waveform; defines energy absorption capacity. |

| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at VWM) across temperature and lifetime. |
Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role: Bidirectional voltage clamp placed between signal line and ground, absorbing transients before they reach sensitive IC pins. Use Value: Maintains signal integrity during 500 W surges while limiting clamped voltage to ≤10.3 V-below absolute maximum ratings of most automotive-grade transceivers. |
Use Scenario: Safeguarding PLC digital input modules against field-wiring induced surges and relay coil flyback. IC Role / Device Role: Primary surge shunt on 24 V DC input lines, positioned upstream of optocoupler or Schmitt trigger input stages. Use Value: Withstands repeated 48.5 A surges without degradation, enabling >100,000 surge cycles per IEC 61000-4-5 compliance testing. |
| Telecom Line Interface | Consumer Power Adapter ESD Protection |
Use Scenario: Shielding Ethernet PHY magnetics secondary side and RS-485 transceiver lines from lightning-induced surges. IC Role / Device Role: Secondary-side TVS on isolated data lines, working in coordination with primary-side GDT or MOV. Use Value: Low clamping voltage (≤10.3 V) prevents latch-up in RS-485 receivers while supporting 10/1000 µs waveform immunity up to Level 4. |
Use Scenario: Input-stage surge suppression on USB-C PD and AC/DC adapter 5–20 V rails exposed to user-handling ESD and hot-plug transients. IC Role / Device Role: Fast-response bidirectional clamp on VBUS or auxiliary power lines, placed adjacent to connector. Use Value: Sub-1 ns response time and 500 W rating meet IEC 61000-4-2 Level 4 (15 kV air/8 kV contact) and IEC 61000-4-5 requirements in compact form factor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ6.0A | Unidirectional only; same VWM/VBR/PPPM, but requires external polarity management for AC signals. | Not suitable for floating or AC-coupled lines without added diodes or layout changes. | Select only if circuit topology guarantees unidirectional transients and space allows polarity-aware placement. |
| ON Semiconductor 1.5SMC6.0CA | Same bidirectional function and VWM, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); 600 W PPPM. | Higher power margin but incompatible with SMA footprints; requires PCB redesign. | Choose when higher surge margin is needed and board space permits larger package; not drop-in compatible. |
Compared with SMA5J6.0CAHM3_A/H, SMAJ6.0A lacks bidirectional capability requiring circuit-level adaptation, while 1.5SMC6.0CA offers +100 W surge headroom at the cost of footprint incompatibility-making SMA5J6.0CAHM3_A/H optimal for space-constrained, polarity-agnostic designs needing AEC-Q101 and halogen-free compliance.

FAQ
What does the "HM3" suffix indicate in SMA5J6.0CAHM3_A/H?
The HM3 suffix in SMA5J6.0CAHM3_A/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms compliance with JESD201 Class 2 whisker resistance, MSL Level 1 reflow capability (260 °C peak), and automotive-grade reliability testing-distinct from commercial-grade M3 or E3 variants. SMA5J6.0CAHM3_A/H meets these specifications per Vishay Document Number 88875.
Is SMA5J6.0CAHM3_A/H bidirectional, and how is polarity identified?
Yes, SMA5J6.0CAHM3_A/H is a bidirectional TVS diode-its CA suffix explicitly indicates symmetrical clamping behavior in both polarities. Unlike unidirectional variants, it has no cathode band marking; both terminals are functionally identical. This eliminates polarity orientation concerns during automated placement and simplifies layout for AC or floating signal lines.
What is the clamping voltage of SMA5J6.0CAHM3_A/H at its rated surge current?
SMA5J6.0CAHM3_A/H clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured per standard test conditions defined in ANSI/IEEE C62.35 and confirmed in Vishay's Electrical Characteristics table for SMA5J6.0CA. It defines the upper voltage limit imposed on protected circuitry during surge events.
Can SMA5J6.0CAHM3_A/H replace SMA5J6.0A in an existing design?
No-SMA5J6.0CAHM3_A/H is bidirectional while SMA5J6.0A is unidirectional. Swapping them without circuit review risks improper clamping during negative transients. SMA5J6.0CAHM3_A/H requires no polarity alignment, whereas SMA5J6.0A relies on correct cathode orientation. Layout and system-level transient behavior must be revalidated if substituting.
What thermal derating applies to SMA5J6.0CAHM3_A/H above 25 °C ambient?
SMA5J6.0CAHM3_A/H follows the derating curve in Figure 2 of Vishay Document 88875: peak pulse power decreases linearly from 500 W at 25 °C to zero at 150 °C junction temperature. At 85 °C ambient (assuming typical RθJA = 80 °C/W), usable PPPM drops to ~350 W. Designers must calculate actual TJ using power dissipation and PCB copper area to ensure operation within 150 °C limit.
