Product details
Overview
TPSMC6.8HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for high-energy surge protection on power and signal lines. It features 6.12 V to 7.48 V breakdown voltage (VBR), 5.5 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 10.8 V clamping voltage at 139 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPSMC6.8HE3_A/I datasheet, TPSMC6.8HE3_A/I pinout, TPSMC6.8HE3_A/I application, or TPSMC6.8HE3_A/I equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, MSL Level 1 moisture sensitivity, and compatibility with 13" tape-and-reel automated assembly for automotive and industrial PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress. Its 10.8 V maximum clamping voltage at 139 A IPPM ensures robust overvoltage protection for downstream ICs and MOSFETs during inductive switching events.
The device operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance. Its DO-214AB package supports 0.31" × 0.31" copper pad layout per Vishay's thermal derating guidelines for sustained 1500 W pulse handling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A-E3/5BT | Lower PPPM (400 W), SMA package (smaller thermal mass), same VBR range and AEC-Q101 qualification | Not suitable for 1500 W surge events; limited to lower-energy transients in space-constrained designs | Select when board area is constrained and surge threat level is ≤400 W (e.g., USB ports, low-power sensors) |
| 1.5KE6.8A | Through-hole TO-218 package, higher IFSM (200 A), same VWM/VC, no AEC-Q101 qualification | Lacks automotive qualification; requires wave soldering or hand assembly; unsuitable for automated SMT lines | Select for legacy through-hole systems or prototyping where AEC-Q101 is not required and manual assembly is acceptable |
Compared with SMAJ6.8A-E3/5BT and 1.5KE6.8A, the TPSMC6.8HE3_A/I uniquely combines 1500 W surge capacity, AEC-Q101 compliance, and DO-214AB SMT compatibility-making it the only option qualified for high-reliability automotive power rail protection with automated manufacturing.

FAQ
What is the clamping voltage of the TPSMC6.8HE3_A/I at its rated peak pulse current?
The TPSMC6.8HE3_A/I has a maximum clamping voltage (VC) of 10.8 V at its rated peak pulse current (IPPM) of 139 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical overvoltage thresholds during surge events. The TPSMC6.8HE3_A/I maintains this clamping performance across its full operating temperature range.
Is the TPSMC6.8HE3_A/I suitable for automotive applications?
Yes, the TPSMC6.8HE3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain applications. Its DO-214AB package, MSL Level 1 rating, and JESD201 Class 2 whisker resistance meet automotive manufacturing and reliability requirements. The TPSMC6.8HE3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product list.
What does the "HE3_A/I" suffix indicate in TPSMC6.8HE3_A/I?
The "HE3" denotes RoHS-compliant construction and AEC-Q101 qualification; "A" indicates ±5 % tolerance on VBR; and "I" specifies packaging in 13" diameter plastic tape and reel with 3500 units per reel. This full suffix identifies the exact variant with verified electrical specs, qualification status, and logistics configuration. The TPSMC6.8HE3_A/I is distinct from HE3_H (7" reel) or non-A variants (±10 % tolerance).
How does the TPSMC6.8HE3_A/I compare to bidirectional TVS diodes?
The TPSMC6.8HE3_A/I is unidirectional and protects only positive transients relative to ground-unlike bidirectional types that suppress both polarities. Its 5.5 V stand-off allows integration on DC lines where reverse conduction must be blocked. For AC or floating signal lines, a bidirectional device would be required; the TPSMC6.8HE3_A/I is optimized for 12 V/24 V automotive and industrial DC systems.
What is the maximum reverse leakage current of the TPSMC6.8HE3_A/I at 25 °C and VWM?
At 25 °C and its 5.5 V stand-off voltage (VWM), the TPSMC6.8HE3_A/I exhibits a maximum reverse leakage current (IR) of 1000 µA. This value increases to 10,000 µA at 150 °C, as specified in the Vishay datasheet. The TPSMC6.8HE3_A/I maintains low leakage to avoid loading sensitive 5 V logic or sensor bias networks under normal operation.
