Product details
Overview
SMA6J6.0A-TR from STMicroelectronics is a unidirectional 600 W transient voltage suppression (TVS) diode designed for primary-level ESD and surge protection in DC power rails and signal lines. It features a 6.0 V stand-off voltage (VRM), 9.5 V clamping voltage at 61 A peak pulse current (8/20 μs), and operates up to 175 °C junction temperature - enabling robust protection in automotive body electronics, industrial I/O modules, and telecom power supplies.
For engineers reviewing the SMA6J6.0A-TR datasheet, SMA6J6.0A-TR pinout, SMA6J6.0A-TR application, or SMA6J6.0A-TR equivalent, this page delivers verified electrical parameters, JEDEC DO-214AC package mapping, thermal derating curves, IEC 61000-4-2/4-4 compliance data, and real-world selection guidance for high-reliability overvoltage protection design.
Technical Context
This TVS diode uses planar silicon technology to achieve low leakage (≤0.2 µA @ 25 °C) and stable breakdown behavior across -55 °C to +175 °C operating range. Its dynamic resistance of 0.034 Ω (25 °C) ensures minimal voltage overshoot during fast transients like ESD contact discharge (30 kV) and 4 kV IEC 61000-4-4 ring wave surges.
The device complies with J-STD-020 MSL Level 1, UL94 V0 resin, and IPC7531 footprint standards. Its DO-214AC (SMA) package supports automated assembly and provides thermal impedance of ~100 °C/W on FR4 with recommended copper land pattern - critical for sustained 600 W (10/1000 μs) pulse handling without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 6.0 V - Maximum continuous reverse working voltage before significant leakage; sets minimum system rail margin for reliable clamping activation. |
| Breakdown Voltage (VBR) | 6.70–7.41 V @ 1 mA - Tight 10.5% tolerance ensures predictable turn-on timing across temperature and production lots. |
| Clamping Voltage (VCL) | 9.5 V @ 61 A (8/20 μs) - Limits downstream IC stress to safe levels during 4 kV surge events per IEC 61000-4-4 Level 4. |
| Peak Pulse Power (PPP) | 600 W @ 10/1000 μs - Sustains industrial-grade lightning-induced surges on 24 V control lines without degradation. |
| Junction Temperature Range | -55 °C to +175 °C - Enables deployment in under-hood automotive ECUs and high-ambient industrial enclosures without derating. |
| Leakage Current (IRM) | ≤0.2 µA @ 25 °C - Minimizes standby power loss in battery-backed sensors and low-power IoT nodes. |
| ESD Withstand (IEC 61000-4-2) | 30 kV air/contact discharge - Exceeds Level 4 requirements, eliminating need for secondary ESD stages in front-end interfaces. |
Pinout & Package
Package: DO-214AC (SMA), JEDEC registered outline, UL94 V0 epoxy molded case, matte tin-plated leads compliant with JESD-22-B102 E3 and MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts transient energy to ground when VREV exceeds VBR. |
| Anode | Reference / ground return path | Must be tied to low-impedance system ground plane to maintain specified VCL and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Planar junction construction | Enables <0.2 µA leakage at 25 °C and stable VBR drift ≤5.9 × 10−4/°C - critical for precision sensor front-ends. |
| Low dynamic resistance (RD) | 0.034 Ω @ 25 °C - Reduces clamping voltage rise during fast 8/20 μs surges, improving protection margin for 3.3 V/5 V logic. |
| High Tj rating (175 °C) | Supports placement near heat-generating components (e.g., power MOSFETs, DC-DC inductors) without thermal shutdown risk. |
| UL94 V0 & J-STD-020 MSL 1 | Enables lead-free reflow compatibility and eliminates flame propagation risk in enclosed industrial housings. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
|
Use Scenario: 12 V supply rail protection against load dump and ISO 7637-2 pulse 5a transients. IC Role / Device Role / Timing Role: Primary clamping device placed upstream of LDO regulators and microcontroller power pins. Use Value: Clamps 9.5 V at 61 A, limiting downstream voltage stress to <10 V - within absolute maximum ratings of automotive-grade MCUs and CAN transceivers. |
Use Scenario: 24 V digital input protection against field-wiring induced surges and ESD from operator touch panels. IC Role / Device Role / Timing Role: Front-end TVS on optocoupler input side, absorbing >4 kV IEC 61000-4-4 bursts before signal conditioning circuitry. Use Value: 600 W (10/1000 μs) rating sustains repeated 2 kV surge events without parameter shift - validated per IEC 61000-4-5 Annex B. |
| Telecom Power Supply OVP | Medical Patient Monitor Signal Line |
|
Use Scenario: Overvoltage protection on +48 V DC telecom rectifier outputs exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Secondary protection stage after MOV-based primary filtering, providing precise clamping with low capacitance. Use Value: 10 pF junction capacitance at 0 V (per SMA6J6.0A curve) avoids signal integrity degradation on high-speed monitoring buses (e.g., RS-485). |
Use Scenario: ESD protection on isolated analog sensor inputs (e.g., ECG leads) where leakage must remain <1 nA to prevent baseline drift. IC Role / Device Role / Timing Role: Unidirectional TVS placed between patient-side electrode and isolation barrier, referenced to safety ground. Use Value: 0.2 µA max leakage at 25 °C meets IEC 60601-1 8.8.2 leakage current limits for applied parts - no additional filtering required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0AHE3_A/H (Vishay) | Same DO-214AC package, 6.0 V VRM, but higher VCL = 10.5 V @ 60 A (8/20 μs); 0.042 Ω RD. | Marginally lower surge current handling (60 A vs. 61 A); less suitable for 24 V systems with tight 12 V downstream headroom. | Select if sourcing diversity is required and 1.0 V higher clamping is acceptable in your voltage budget. |
| P6SMB6.0A (ON Semiconductor) | DO-214AA (SMB) package, same 6.0 V VRM, but lower PPP = 600 W only at 25 °C ambient; derates to 300 W at 100 °C. | Requires larger PCB footprint (SMB vs. SMA); not rated for 175 °C operation - unsuitable for under-hood use. | Prefer for cost-sensitive consumer applications where ambient stays <70 °C and space allows SMB layout. |
Compared with SMA6J6.0A-TR, SMA6J6.0AHE3_A/H trades 1.0 V higher clamping for identical thermal capability, while P6SMB6.0A sacrifices high-temperature reliability and package compactness for legacy footprint compatibility - making the ST device optimal for space-constrained, high-ambient industrial and automotive designs.

FAQ
What is the maximum allowable soldering temperature profile for SMA6J6.0A-TR?
The device follows JEDEC J-STD-020 MSL Level 1 guidelines: peak reflow temperature is 240–245 °C for ≤30 seconds, with ramp rates limited to 2–3 °C/s pre-peak and ≤6 °C/s cooling. ST recommends minimizing convection airflow to prevent component movement during reflow - verified per DS5142 Rev 11 Figure 21.
Does SMA6J6.0A-TR meet AEC-Q200 stress testing requirements?
No - SMA6J6.0A-TR is not AEC-Q200 qualified. While it operates up to 175 °C junction temperature and passes IEC 61000-4-2/4-4, ST does not list it in their AEC-Q200 stress-tested TVS portfolio. For automotive qualification, consider ST's Automotive-grade SMAJ6.0A (Q-level marked) variant instead.
How does junction temperature affect clamping voltage performance?
VCL increases linearly with junction temperature at αT = 5.9 × 10−4/°C. At 150 °C, VCL rises by ~0.7 V versus 25 °C (9.5 V → ~10.2 V @ 61 A). This is calculated using VCL(Tj) = VCL(25°C) × [1 + αT × (Tj − 25)], per DS5142 Table 2 footnote 2.
Can SMA6J6.0A-TR be used in bidirectional configurations?
No - SMA6J6.0A-TR is unidirectional only (anode-cathode polarity). For bidirectional protection, use SMA6J6.0CA-TR, which has symmetrical breakdown in both directions and identical VBR/VCL specs. Mixing A and CA types in the same circuit risks reverse-bias failure.
