Product details
Overview
SMA6J10A from Taiwan Semiconductor is a 600W surface-mount transient voltage suppressor (TVS) diode with 10V working standoff voltage (VWM), 11.1–12.3V breakdown voltage (VBR), and 38.2V clamping voltage (VC) at 5.0A peak pulse current, designed for overvoltage protection in DC/DC converters and SMPS inputs.
For engineers reviewing the SMA6J10A datasheet, SMA6J10A pinout, SMA6J10A application, or SMA6J10A equivalent, key selection criteria include clamping performance under 10/1000μs surge, DO-214AC package compatibility with automated SMT lines, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and junction temperature range of –55°C to +175°C.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-1.0ps response time and stable clamping during fast transients. Its single-die DO-214AC (SMA) configuration supports polarity identification via cathode band and meets JESD201 Class 2 whisker resistance.
The device operates within –55°C to +175°C junction temperature range, delivers 4W steady-state power dissipation, and withstands 50A non-repetitive forward surge (8.3ms half-sine). Clamping voltage is specified at 38.2V for 5.0A IPPM per 10/1000μs waveform.
Key Specifications

|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR @ IT=1mA | 11.1–12.3 V - Breakdown threshold where device transitions from high-impedance to low-impedance conduction |
| VC @ IPPM=5.0A | 38.2 V - Clamped voltage limiting downstream circuit stress during 10/1000μs surge |
| PPPM | 600 W - Peak pulse power handling capability under standardized 10/1000μs transient waveform |
| IR @ VWM | 5.0 µA - Reverse leakage current at rated standoff voltage, ensuring minimal standby power loss |
| TJ Range | –55°C to +175°C - Operational junction temperature envelope supporting automotive under-hood and industrial environments |

Applications
| Switching Mode Power Supply (SMPS) | On-board DC/DC Converter |
|---|---|
Use Scenario: Input stage protection against line surges and coupling transients in AC/DC front-end or isolated DC/DC modules. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and ground to limit voltage excursions during ISO 7637-2 Pulse 2a/3b events. Use Value: 38.2V clamping at 5.0A ensures downstream rectifiers and controllers remain below absolute maximum ratings during 10/1000μs transients. | Use Scenario: Protection of point-of-load (POL) converter inputs in telecom or server boards exposed to board-level coupling noise. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12V or 24V intermediate bus rails to absorb coupled spikes from adjacent switching regulators. Use Value: 10V VWM allows use on 9V nominal rails while maintaining margin; 600W PPPM handles repetitive low-energy transients without degradation. |
| Lighting Application | Adapter Input Stage |
Use Scenario: Overvoltage safeguard in LED driver inputs subjected to mains-borne surges and hot-plug transients. IC Role / Device Role / Timing Role: Primary-side transient suppressor mounted directly at AC/DC adapter output or constant-current driver input terminals. Use Value: DO-214AC footprint enables compact layout near connectors; 175°C TJ max supports enclosed high-temperature luminaire environments. | Use Scenario: Input protection in wall-mounted AC/DC adapters for consumer electronics, guarding against lightning-induced surges on secondary side. IC Role / Device Role / Timing Role: Unidirectional clamping device placed between transformer secondary and rectifier output to limit voltage seen by bulk capacitor and controller. Use Value: 38.2V VC limits stress on 35V-rated electrolytic capacitors; low IR (5.0µA) prevents discharge during no-load standby. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A (ON Semiconductor) | Same DO-214AC package; 10.0V VWM, 11.1V min VBR, 39.0V VC @ 5.0A - 0.8V higher clamping than SMA6J10A | Identical ISO 7637-2 coverage but slightly lower surge margin due to higher VC | Preferred where legacy ON Semi BOMs exist and 0.8V clamping increase is acceptable |
| P6SMB10A (Littelfuse) | DO-214AA (SMB) package; 10.0V VWM, 11.1V min VBR, 35.0V VC @ 6.3A - lower VC but 20% larger footprint | Higher IPPM rating (6.3A vs 5.0A) but incompatible pad layout due to SMB body size | Selected when higher surge current headroom is prioritized and PCB real estate permits SMB placement |
Compared with SMAJ10A and P6SMB10A, the SMA6J10A offers the lowest clamping voltage in DO-214AC form factor, enabling tighter protection margins on 12V rails while maintaining full automotive transient compliance and SMT process compatibility.

FAQ
What is the clamping voltage of SMA6J10A at its rated peak pulse current?
The SMA6J10A has a maximum clamping voltage (VC) of 38.2 V when subjected to a 5.0 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during transient events, ensuring downstream components remain within safe operating limits.
Does SMA6J10A meet automotive transient immunity standards?
Yes, SMA6J10A meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, making it suitable for 12 V and 24 V automotive electrical systems. Its 600 W peak pulse power rating, sub-1.0 ps response time, and –55°C to +175°C junction temperature range align with OEM-level surge immunity specifications without requiring additional filtering components.
What is the package type and mounting compatibility of SMA6J10A?
SMA6J10A uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. It supports standard reflow profiles, requires no pre-bake (MSL Level 1), and fits automated pick-and-place equipment - ideal for high-volume manufacturing of power conversion and lighting PCBs.
How does the breakdown voltage specification of SMA6J10A compare to its working standoff voltage?
SMA6J10A has a working standoff voltage (VWM) of 10 V and a minimum breakdown voltage (VBR) of 11.1 V at 1 mA test current. This 1.1 V margin ensures reliable blocking of normal operating voltages while guaranteeing rapid avalanche conduction onset during overvoltage events - a critical design parameter for stable protection without false triggering.
Is SMA6J10A halogen-free and RoHS-compliant?
Yes, SMA6J10A is both halogen-free per IEC 61249-2-21 and RoHS-compliant per EU Directive 2011/65/EU. The molding compound is UL 94V-0 rated, and the device carries no restricted substances above threshold limits, supporting environmental compliance for global electronics markets including automotive, industrial, and consumer applications.
