Product details
Overview
TPSMA11HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping inductive switching and lightning-induced transients on signal lines and power rails. It features 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 25.6 V maximum clamping voltage (VC) at 5.0 A peak pulse current, 400 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the TPSMA11HE3_A/I datasheet, TPSMA11HE3_A/I pinout, TPSMA11HE3_A/I application, or TPSMA11HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, 1.0 W steady-state power dissipation, and compatibility with 0.2" × 0.2" PCB copper pad layout per JEDEC standards.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown. Its passivated anisotropic rectifier technology ensures stable clamping performance across -65 °C to +185 °C operating range, with low incremental surge resistance enabling fast response to transient events.
The device is rated for non-repetitive 10/1000 µs waveform surges up to 400 W, with derating above 25 °C per Fig. 2. It meets JESD201 Class 2 whisker resistance and is qualified to AEC-Q101 for automotive underhood applications requiring high thermal reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same SMA package, 11 V VBR, but rated for 400 W with 1.0 µA IR at VWM; not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| TPSMA11AHM3_A/I | Halogen-free variant of same base part; identical electrical specs and AEC-Q101 qualification | No functional difference; required only where halogen-free compliance is mandated | Choose if RoHS + halogen-free material declaration is mandatory per customer BOM policy |
Compared with SMAJ11A and TPSMA11AHM3_A/I, the TPSMA11HE3_A/I provides verified AEC-Q101 qualification and RoHS compliance without halogen restrictions - making it the preferred choice for Tier-1 automotive suppliers needing traceable, high-temperature-stable TVS protection in production programs.

FAQ
What is the maximum clamping voltage of the TPSMA11HE3_A/I under a 10/1000 µs surge?
The TPSMA11HE3_A/I has a maximum clamping voltage (VC) of 25.6 V when subjected to a 5.0 A peak pulse current with a 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 88405) and reflects worst-case clamping performance at TA = 25 °C. The actual clamped voltage remains consistent across its full operating temperature range due to low temperature coefficient (0.067 %/°C).
Is the TPSMA11HE3_A/I qualified for automotive applications?
Yes, the TPSMA11HE3_A/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision dated 23-Jan-2024. It undergoes rigorous stress testing including high-temperature reverse bias (HTRB), temperature cycling, and ESD per AEC-Q101 requirements. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified variants, making TPSMA11HE3_A/I suitable for under-hood and chassis-mounted automotive systems.
What is the standoff voltage (VWM) and why does it matter for TPSMA11HE3_A/I?
The standoff voltage (VWM) of the TPSMA11HE3_A/I is 9.40 V - the maximum continuous reverse voltage it can block without exceeding 1.0 µA leakage current. This parameter ensures reliable operation on 9 V nominal systems (e.g., automotive battery-supplied sensors) without false triggering during normal operation. Exceeding VWM risks premature conduction and accelerated wear, so proper margining against system operating voltage is essential in layout design.
Does the TPSMA11HE3_A/I have a defined moisture sensitivity level (MSL)?
Yes, the TPSMA11HE3_A/I is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions and withstand lead-free reflow profiles with peak temperatures up to 260 °C without baking. This eliminates pre-reflow moisture mitigation steps in manufacturing, reducing process complexity and cost for high-volume SMT assembly of boards using TPSMA11HE3_A/I.
How does the junction temperature rating of 185 °C impact real-world use of TPSMA11HE3_A/I?
The 185 °C maximum junction temperature allows the TPSMA11HE3_A/I to operate reliably in extreme thermal environments such as engine control units, transmission control modules, and industrial motor drives. Unlike standard TVS diodes rated to 150 °C, this rating supports extended lifetime under sustained high-power dissipation and elevated ambient temperatures - validated through HTOL and thermal cycling tests per AEC-Q101, directly enhancing field reliability of systems using TPSMA11HE3_A/I.
