Product details
Overview
SMA6J6.0AHM3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 6.7 V minimum breakdown voltage (VBR), 6.0 V stand-off voltage (VWM), and 9.5 V maximum clamping voltage (VC) at 63.2 A peak pulse current (IPP) under 10/1000 µs waveform. It delivers 600 W peak pulse power dissipation and is designed for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J6.0AHM3/5A datasheet, SMA6J6.0AHM3/5A pinout, SMA6J6.0AHM3/5A application, or SMA6J6.0AHM3/5A equivalent, key selection criteria include verified unidirectional polarity, clamping performance at 63.2 A IPP, thermal resistance (RθJA = 120 °C/W), MSL Level 1 compliance, and halogen-free RoHS-compliant construction per suffix M3.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, triggering above its 6.7 V breakdown threshold to divert surge current away from downstream circuitry. Its dynamic resistance (RD = 0.033 Ω) and low clamping ratio (VC/VBR ≈ 1.42) ensure tight overvoltage control during 10/1000 µs transients.
Designed for PCB-level protection of DC power rails and low-speed signal lines, it supports operation from -55 °C to +150 °C junction temperature and maintains stable leakage (<600 µA at VWM) across temperature. The SMA package enables automated placement and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 6.7 V - Ensures reliable turn-on above normal 6.0 V rail; avoids false triggering during ripple or tolerance drift |
| VC @ IPP (10/1000 µs) | 9.5 V - Limits protected node voltage to safe level during 63.2 A surge, preserving 3.3 V/5 V IC integrity |
| PPPM (10/1000 µs) | 600 W - Sustains standard lightning/surge immunity tests (IEC 61000-4-5 Level 3) on compact PCB layouts |
| IFSM | 50 A - Withstands 8.3 ms half-sine inrush or fault currents without bond wire failure |
| RθJA | 120 °C/W - Requires ≥5.0 mm × 5.0 mm copper pads per terminal for full 4 W derated power handling at 50 °C ambient |
| Leakage @ VWM | 600 µA max - Minimizes standby power loss in battery-backed or energy-sensitive circuits |
| TJ max | +150 °C - Enables use in under-hood automotive modules or enclosed industrial enclosures without forced cooling |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional polarity with cathode band marking. Matte tin-plated leads, compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| MSL Level 1 rating | Zero floor life limitation; supports standard SMT reflow without dry-pack or baking preconditioning |
| Low dynamic resistance (0.033 Ω) | Reduces VC rise under high di/dt surges, improving clamping accuracy for fast-rising transients |
| 150 °C max junction temperature | Enables deployment in thermally constrained environments such as sealed power supplies or motor drive PCBs |
| UL 94 V-0 molding compound | Prevents flame propagation during catastrophic overvoltage events, supporting safety certification (e.g., UL 62368-1) |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and bootstrap circuits against inductive kickback from IGBT/MOSFET switching in variable-frequency drives. IC Role / Device Role / Timing Role: Shunt clamping device placed directly at power stage input to clamp voltage spikes before they reach driver ICs.

Use Scenario: Input rail protection in AC/DC front-end converters exposed to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary surge suppression element upstream of bulk capacitors and PFC controllers. Use Value: Absorbs 600 W (10/1000 µs) without degradation, maintaining system uptime during repeated 1 kV/2 Ω surge events. |
| Automotive Body Control Modules | Consumer Sensor Interfaces |
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and ISO 7637-2 Pulse 1/2a transients. IC Role / Device Role / Timing Role: Localized TVS at connector entry point, co-located with ESD diodes for multi-threat mitigation. Use Value: Clamps 63.2 A pulses within 1 ns response time, limiting voltage to 9.5 V and preserving 5 V MCU GPIO integrity. |
Use Scenario: Signal line hardening for analog outputs (e.g., 4–20 mA loops) and digital interfaces (I²C, UART) in smart home sensors. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) transient suppressor placed inline with sensor output traces. Use Value: Adds <1.5 V overhead to signal swing while suppressing ±30 V transients, enabling sub-1% measurement error in precision ADC systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A-E3/5A | RoHS-compliant but contains brominated flame retardants; no halogen-free certification | Acceptable for non-automotive industrial use where halogen-free mandate does not apply | Select when cost sensitivity outweighs halogen-free requirement and MSL Level 1 compatibility is retained |
| SMCJ6.0A-M3 | Higher 1500 W PPPM (10/1000 µs); DO-214AB (SMC) package; 2.5× larger footprint | Used where higher surge margin is required and board space permits larger package | Choose only if design requires >600 W surge rating; not drop-in due to different pad layout and thermal mass |
Compared with SMA6J6.0AHM3/5A, the E3/5A variant trades halogen-free status for lower unit cost, while SMCJ6.0A-M3 offers higher surge capacity at the expense of PCB area and thermal coupling-neither is pin-compatible, requiring layout revision for substitution.

FAQ
What is the clamping voltage of SMA6J6.0AHM3/5A at its rated peak pulse current?
The SMA6J6.0AHM3/5A has a maximum clamping voltage (VC) of 9.5 V at 63.2 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting during surge events. The SMA6J6.0AHM3/5A achieves this with a dynamic resistance of 0.033 Ω, contributing to consistent clamping behavior across production lots.
Does SMA6J6.0AHM3/5A support lead-free reflow assembly?
Yes, SMA6J6.0AHM3/5A is qualified for lead-free reflow per J-STD-020 with MSL Level 1 rating and a maximum peak temperature of 260 °C. Its matte tin-plated terminals meet JESD 22-B102 solderability requirements, and the package uses UL 94 V-0 compliant molding compound. No pre-baking is required prior to SMT placement, simplifying manufacturing flow for the SMA6J6.0AHM3/5A.
Is SMA6J6.0AHM3/5A unidirectional or bidirectional?
SMA6J6.0AHM3/5A is unidirectional only, as confirmed in the Vishay datasheet "Features" section and electrical characteristics table. Polarity is marked by a cathode band; the device conducts only during reverse-biased overvoltage events. It must be oriented with cathode toward the protected line and anode to ground. Bidirectional variants (e.g., SMA6J6.0CA) are separate part numbers and not interchangeable with SMA6J6.0AHM3/5A.
What is the thermal resistance of SMA6J6.0AHM3/5A, and how does it affect layout?
The SMA6J6.0AHM3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To achieve rated 4 W power dissipation at TA = 50 °C, PCB layout must provide these minimum pad dimensions and avoid thermal isolation. Reducing pad size increases RθJA, derating both power handling and surge repetition rate for the SMA6J6.0AHM3/5A.
How does the M3 suffix in SMA6J6.0AHM3/5A differ from E3?
The M3 suffix in SMA6J6.0AHM3/5A denotes halogen-free, RoHS-compliant construction meeting IPC-1752A material declarations, whereas E3 indicates RoHS-compliant but brominated flame-retardant packaging. Both meet JESD 201 Class 2 whisker resistance and MSL Level 1, but only M3 satisfies strict halogen-free mandates (e.g., JEDEC JS709E). The SMA6J6.0AHM3/5A is functionally identical to E3 versions except for material composition.
