Product details
Overview
TPSMA13HE3/61T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, and 185 °C maximum junction temperature - enabling robust protection in automotive and industrial power rails.
For engineers reviewing the TPSMA13HE3/61T datasheet, TPSMA13HE3/61T pinout, TPSMA13HE3/61T application, or TPSMA13HE3/61T equivalent, key selection criteria include unidirectional polarity, 400 W peak pulse power rating (10/1000 μs), AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with high-reliability PCB layouts using 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by overvoltage events such as inductive switching surges or lightning-induced transients. Its passivated anisotropic rectifier structure ensures stable breakdown behavior up to 185 °C junction temperature, with low incremental surge resistance enabling precise clamping under fast-rising 10/1000 μs waveforms.
The device is optimized for unidirectional operation only, with cathode marked by a band. It meets JESD22-B102 solderability standards and JESD201 Class 2 whisker resistance, and its thermal derating follows Fig. 2 in the datasheet - maintaining 400 W peak pulse power only at TA ≤ 25 °C, decreasing linearly above that.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines reliable conduction onset under transient stress; used to set minimum system overvoltage threshold |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 1 μA; must exceed normal operating rail voltage |
| VC @ IPPM | 18.2 V - clamped voltage during 22.0 A surge; determines maximum stress imposed on downstream ICs or MOSFETs |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; defines transient energy absorption capability |
| TJ max. | 185 °C - enables operation in under-hood automotive environments and high-temperature industrial enclosures |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation relative to protected line |
| MSL Level | Level 1 (J-STD-020) - supports standard reflow without dry-pack or baking requirements |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with matte tin-plated leads. Cathode indicated by color band. Compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VBR (13.0 V), but SMB (DO-214AA) package; 600 W PPPM; 25.5 A IPPM | Higher power handling, larger footprint (5.3 mm × 4.6 mm vs. 4.9 mm × 3.9 mm) | Select when board space allows and >400 W surge margin is required |
| TPSMA13AHM3/61T | Identical electrical specs; halogen-free molding compound; same AEC-Q101 qualification | No functional difference; preferred where RoHS + halogen-free compliance is mandated | Drop-in replacement if halogen-free material specification applies |
Compared with SMBJ13A and TPSMA13AHM3/61T, the TPSMA13HE3/61T offers identical clamping performance in a smaller SMA footprint and is optimized for cost-sensitive, space-constrained automotive and industrial designs requiring AEC-Q101 validation without halogen restrictions.

FAQ
What is the maximum clamping voltage of the TPSMA13HE3/61T under a 10/1000 μs surge?
The TPSMA13HE3/61T has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22.0 A under the standardized 10/1000 μs waveform. This value is measured per Figure 3 in the Vishay datasheet 88405 and defines the upper voltage limit imposed on protected circuitry during transient events. The TPSMA13HE3/61T maintains this clamping performance across its full operating temperature range up to 185 °C.
Is the TPSMA13HE3/61T qualified for automotive use?
Yes, the TPSMA13HE3/61T is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101-qualified construction. It is rated for TJ = -65 °C to +185 °C and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 requirements - making it suitable for under-hood and body-control module applications. The TPSMA13HE3/61T is explicitly listed in Vishay's AEC-Q101 qualified product table.
What is the standoff voltage (VWM) of the TPSMA13HE3/61T, and why does it matter?
The standoff voltage (VWM) of the TPSMA13HE3/61T is 11.1 V - the maximum DC or continuous reverse voltage the device can block without exceeding 1 μA leakage current. This parameter ensures the TPSMA13HE3/61T remains non-conductive during normal operation (e.g., on a 12 V automotive rail), avoiding power loss or false triggering. Selecting a VWM ≥ 110 % of nominal system voltage prevents nuisance conduction while retaining sufficient margin for transients.
Does the TPSMA13HE3/61T have bidirectional capability?
No, the TPSMA13HE3/61T is unidirectional only, as stated in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It clamps positive transients relative to its cathode terminal and conducts only when the cathode is at higher potential than the anode. For bidirectional protection, two TPSMA13HE3/61T devices would need back-to-back configuration, or a dedicated bidirectional part like SMBJ13CA must be selected instead.
What is the thermal derating behavior of the TPSMA13HE3/61T above 25 °C ambient?
The TPSMA13HE3/61T follows the derating curve in Figure 2 of datasheet 88405: its 400 W peak pulse power rating decreases linearly as ambient temperature rises above 25 °C, reaching zero at approximately 175 °C. At 125 °C ambient, the usable PPPM is ~200 W. This derating directly impacts surge survivability in high-temperature enclosures and must be factored into layout design - including copper pad area (minimum 5.0 mm × 5.0 mm per terminal) and airflow considerations for the TPSMA13HE3/61T.
