Product details
Overview
SMA6J5.0A01HM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 9.1 V maximum clamping voltage (VC) at 65.9 A IPP (10/1000 μs), 600 W peak pulse power rating, and operates across –55 °C to +150 °C junction temperature range.
For engineers reviewing the SMA6J5.0A01HM3_A/I datasheet, SMA6J5.0A01HM3_A/I pinout, SMA6J5.0A01HM3_A/I application, or SMA6J5.0A01HM3_A/I equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity compatibility with DC-biased circuits, thermal resistance (RθJA = 120 °C/W), RoHS/halogen-free compliance (M3 suffix), and PCB-mount reliability per J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered above its reverse breakdown threshold, diverting transient energy to ground while limiting downstream voltage to ≤9.1 V at 65.9 A. Its low dynamic resistance (RD = 0.031 Ω) ensures minimal voltage overshoot during fast transients, and its MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C.
The SMA6J5.0A01HM3_A/I is optimized for single-pulse surge suppression per IEC 61000-4-5 (10/1000 μs) and high-energy lightning-induced events (8/20 μs), with derated power dissipation above 25 °C and validated performance on 5.0 mm × 5.0 mm copper pads per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before leakage exceeds 150 µA; defines safe DC bias margin. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Tight breakdown window ensures predictable turn-on without premature conduction. |
| VC @ IPP | 9.1 V at 65.9 A (10/1000 μs) - Clamping voltage seen by protected IC/MOSFET during standard surge event. |
| PPPM (10/1000 μs) | 600 W - Peak surge energy handling capability under standardized long-duration waveform. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient on recommended PCB pad layout; dictates power derating. |
| Polarity | Unidirectional - Cathode-band marked; suitable only for DC-biased or positive-rail protection, not AC lines. |
| Package | SMA (DO-214AC) - Surface-mount, low-profile package with matte tin leads; compatible with automated placement. |
Pinout & Package
SMA6J5.0A01HM3_A/I is housed in an SMA (DO-214AC) surface-mount package with two terminals: anode and cathode. The cathode is marked by a color band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected line (e.g., VCC or signal) | Reverse-biased during normal operation; conducts only during overvoltage events when cathode is at higher potential. |
| Cathode | Current exit terminal during clamping; connected to ground or low-impedance return path | Marked by visible band; must be routed to lowest-inductance ground plane to minimize clamping voltage overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping ratio VC/VBR | ≤1.43 - Low ratio ensures tight voltage control during surge, reducing stress on downstream MOSFETs or ICs. |
| Dynamic resistance RD | 0.031 Ω - Enables rapid current rise and stable clamping under high di/dt transients. |
| MSL Level 1 rating | Reflow-compatible up to 260 °C peak - Supports lead-free assembly without baking or special handling. |
| Halogen-free & RoHS | M3 suffix confirms compliance - Meets environmental requirements for industrial and consumer end equipment. |
| Junction temperature range | –55 °C to +150 °C - Validated operation across automotive under-hood and industrial ambient extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-E3/61 | Same electrical specs; RoHS-compliant but contains brominated flame retardants (not halogen-free) | Acceptable where halogen-free requirement is waived (e.g., non-EU industrial equipment) | Select SMA6J5.0A01HM3_A/I when full halogen-free compliance per IEC 61249-2-21 is mandated. |
| SMCJ5.0A-M3 | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; 1500 W PPPM (10/1000 μs) | Used where higher surge energy handling is required and PCB space permits larger footprint | Choose SMA6J5.0A01HM3_A/I for space-constrained designs needing 600 W rating in minimal SMA footprint. |
Compared with SMA6J5.0A-E3/61, the SMA6J5.0A01HM3_A/I adds halogen-free certification without sacrificing clamping performance or thermal rating; versus SMCJ5.0A-M3, it trades surge capacity for 40% smaller board area and lower parasitic inductance due to shorter leadframe geometry.

FAQ
What is the maximum clamping voltage of the SMA6J5.0A01HM3_A/I under a 10/1000 μs surge?
The SMA6J5.0A01HM3_A/I exhibits a maximum clamping voltage (VC) of 9.1 V when subjected to a 65.9 A peak pulse current with a 10/1000 μs waveform. This value is measured at TA = 25 °C on specified PCB pad layout and represents the upper voltage limit imposed on protected circuitry during standardized surge testing. The SMA6J5.0A01HM3_A/I maintains this clamping performance across its rated junction temperature range.
Does the SMA6J5.0A01HM3_A/I support lead-free reflow soldering?
Yes, the SMA6J5.0A01HM3_A/I meets MSL Level 1 per J-STD-020 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards, and the molding compound satisfies UL 94 V-0 flammability requirements. No pre-baking is required prior to assembly.
How does the SMA6J5.0A01HM3_A/I differ from the SMA6J5.0A-E3/61 variant?
The SMA6J5.0A01HM3_A/I and SMA6J5.0A-E3/61 share identical electrical parameters (VWM, VBR, VC, PPPM), but the M3 suffix denotes halogen-free construction per IEC 61249-2-21, whereas the E3 version uses brominated flame retardants. Both are RoHS-compliant, but only the SMA6J5.0A01HM3_A/I satisfies strict halogen-free mandates in green electronics programs.
What is the thermal resistance junction-to-ambient for the SMA6J5.0A01HM3_A/I?
The SMA6J5.0A01HM3_A/I has a typical thermal resistance of RθJA = 120 °C/W when mounted on the minimum recommended PCB pad layout (5.0 mm × 5.0 mm copper pads per terminal). This value governs power derating above 25 °C ambient and must be used to calculate safe operating limits in thermally constrained enclosures or high-temperature environments.
Can the SMA6J5.0A01HM3_A/I be used on AC signal lines?
No - the SMA6J5.0A01HM3_A/I is a unidirectional TVS diode, intended exclusively for DC-biased or positive-rail protection. Its cathode-band marking and asymmetric IV characteristics make it unsuitable for bidirectional AC waveforms. For AC line protection, a bidirectional variant such as SMA6J5.0CA or a back-to-back diode configuration is required.
