Product details
Overview
TPSMP6.8HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of low-voltage signal lines and power rails. It features 6.12 V minimum breakdown voltage (VBR), 5.5 V stand-off voltage (VWM), 23.2 V clamping voltage at 23.2 A peak pulse current, 250 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP6.8HM3/84A datasheet, TPSMP6.8HM3/84A pinout, TPSMP6.8HM3/84A application, or TPSMP6.8HM3/84A equivalent, key selection criteria include its 185 °C junction temperature rating, ultra-low profile (1.0 mm height), MSL Level 1 moisture sensitivity, and uni-directional clamping behavior suitable for DC rail and I/O line protection in harsh environments.
Technical Context
The TPSMP6.8HM3/84A employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and load-dump spikes. Its junction passivation ensures stable performance under thermal cycling and high-humidity conditions.
Designed for surface-mount automated placement on FR-4 PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it delivers 250 W peak pulse power at 25 °C and maintains clamping performance across -65 °C to +185 °C operating junction temperature range, meeting automotive-grade reliability requirements.

IC Role / Device Role / Timing Role: Primary clamping device placed upstream of USB power switch IC to limit fault voltage to safe levels. Use Value: 300 μA leakage at 5.5 V prevents standby current increase, supporting Energy Star compliance. | Use Scenario: Protecting MIPI DSI and I²C lines connecting display driver ICs to central infotainment processors in vehicles. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. 100 pF at 0 V) placed directly at connector to suppress ESD per ISO 10605 (30 kV air, 15 kV contact). Use Value: Fast <1 ns response time prevents data corruption during high-speed serial communication bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A-E3/61 | Higher VC = 11.5 V at 38.2 A; lower PPPM = 400 W; SMA package (2.3 mm height) | Less suitable for ultra-low-profile designs; higher mounting height may interfere with shield cans | Select when higher surge current handling is prioritized over board space constraints |
| 1.5SMC6.8A | Same VBR range but SMC package (2.79 mm height); 600 W PPPM; no AEC-Q101 qualification | Not qualified for automotive use; larger footprint limits routing density in compact modules | Prefer for cost-sensitive industrial applications where automotive qualification is unnecessary |
Compared with SMAJ6.8A-E3/61 and 1.5SMC6.8A, the TPSMP6.8HM3/84A offers the lowest profile (1.0 mm), AEC-Q101 qualification, and optimized thermal resistance for high-reliability automotive PCBs-making it the preferred choice where space, qualification, and thermal performance are jointly constrained.

FAQ
What is the breakdown voltage tolerance of the TPSMP6.8HM3/84A?
The TPSMP6.8HM3/84A has a breakdown voltage (VBR) range of 6.12 V to 7.48 V at 10 mA test current, corresponding to ±10 % tolerance around the nominal 6.8 V rating. This tolerance is confirmed in the Electrical Characteristics table of Vishay document 88471 and applies strictly to the TPSMP6.8HM3/84A variant-not to the broader TPSMP6.8 family. The TPSMP6.8HM3/84A must be selected when this specific tolerance band is required in circuit design.
Is the TPSMP6.8HM3/84A suitable for bidirectional transient protection?
No, the TPSMP6.8HM3/84A is a unidirectional TVS diode and is not rated for bidirectional clamping. Its electrical characteristics-including specified VBR, VWM, and VC-are defined only for reverse-bias operation. Using it in bidirectional configurations (e.g., AC signal lines) would result in forward conduction during half-cycles and potential failure. For bidirectional protection, engineers must select a dedicated bidirectional variant such as TPSMP6.8AHM3/84A or alternate part numbers explicitly marked "bi-directional" in Vishay documentation.
Does the TPSMP6.8HM3/84A meet automotive qualification standards?
Yes, the TPSMP6.8HM3/84A is AEC-Q101 qualified, as stated in the Mechanical Data and Features sections of Vishay document 88471. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, confirming suitability for automotive electronic control units, sensors, and infotainment systems. The HM3 suffix further indicates halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance-key requirements for automotive Tier 1 suppliers.
What is the maximum clamping voltage of the TPSMP6.8HM3/84A under surge conditions?
The maximum clamping voltage (VC) of the TPSMP6.8HM3/84A is 23.2 V at 23.2 A peak pulse current (IPPM) with a 10/1000 µs waveform, as specified in the Electrical Characteristics table. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events and is measured under standardized test conditions with 5.0 mm × 5.0 mm copper pads. Designers must ensure downstream components tolerate up to 23.2 V during surge events when using the TPSMP6.8HM3/84A.
Can the TPSMP6.8HM3/84A be used in lead-free reflow processes?
Yes, the TPSMP6.8HM3/84A meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 for solderability, and the HM3 suffix confirms qualification for high-reliability assembly. No pre-baking is required prior to reflow, simplifying manufacturing flow for high-volume automotive and industrial production.
