Product details
Overview
TPSMP30-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade surge protection with 30 V breakdown voltage (VBR = 27.0–33.0 V), 400 W peak pulse power (10/1000 µs), 9.2 A peak pulse current (IPPM), 24.3 V stand-off voltage (VWM), and 43.5 V clamping voltage (VC) at IPPM, used to safeguard sensor signal lines and drive transistors in harsh automotive environments.
For engineers reviewing the TPSMP30-E3/84A datasheet, TPSMP30-E3/84A pinout, TPSMP30-E3/84A application, or TPSMP30-E3/84A equivalent, key selection criteria include unidirectional polarity, MSL Level 1 moisture sensitivity, 185 °C max junction temperature, RoHS/WEEE compliance, and DO-220AA mechanical compatibility with automated SMT placement.
Technical Context
The TPSMP30-E3/84A employs patented PAR oxide passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its fast response time and low profile (1.0 mm typical height) support high-density PCB layouts in space-constrained automotive modules.
Rated for operation from −65 °C to +185 °C, it delivers stable performance under thermal stress while maintaining 1.0 W steady-state power dissipation and 40 A non-repetitive forward surge current (10 ms half-sine), meeting AEC-Q101 requirements via E3 suffix commercial-grade qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 27.0 V / 33.0 V - ensures reliable triggering above system operating voltage with ±10 % tolerance |
| VWM | 24.3 V - maximum continuous reverse voltage before leakage exceeds 1 µA |
| VC @ IPPM | 43.5 V - clamped voltage during 9.2 A 10/1000 µs surge, limiting downstream IC stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC package (higher profile: 2.3 mm), 33.3 V VWM, 48.4 V VC @ 6.5 A, 400 W PPPM | Less suitable for ultra-low-height modules; higher clamping voltage increases risk to downstream 3.3 V logic | Select when board height >2.0 mm is acceptable and legacy DO-214AC footprint exists |
| TPSMA6.8A | Same DO-220AA package, but 6.8 V VBR range (6.45–7.14 V), 10.5 V VC @ 1000 A, 300 W PPPM | Designed for 5 V rail protection; incompatible with 24 V systems due to premature conduction | Choose only for low-voltage digital I/O protection where VWM ≤5.8 V is required |
Compared with SMAJ30A and TPSMA6.8A, the TPSMP30-E3/84A provides optimal balance of low-profile packaging, precise 24.3 V stand-off, and 43.5 V clamping for 24 V automotive subsystems-enabling direct integration into next-generation ADAS sensor modules without layout or thermal redesign.

FAQ
What is the breakdown voltage range of the TPSMP30-E3/84A?
The TPSMP30-E3/84A has a specified breakdown voltage (VBR) range of 27.0 V to 33.0 V at 10 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots while accommodating thermal drift up to 185 °C junction temperature. The value is confirmed in Vishay Document Number 88937, Table on page 2.
Is the TPSMP30-E3/84A suitable for automotive applications?
Yes, the TPSMP30-E3/84A is qualified to AEC-Q101 standards via its E3 suffix designation, supporting automotive use in engine control units, body electronics, and ADAS sensors. It meets ISO 7637-2 pulse immunity requirements, operates from −65 °C to +185 °C, and carries RoHS/WEEE compliance-making it appropriate for under-hood and cabin-mounted systems.
What is the clamping voltage of the TPSMP30-E3/84A at its rated peak pulse current?
The TPSMP30-E3/84A exhibits a maximum clamping voltage (VC) of 43.5 V at its rated peak pulse current (IPPM) of 9.2 A under 10/1000 µs waveform conditions. This value is measured with 5.0 × 5.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events.
Does the TPSMP30-E3/84A have polarity marking, and how is it identified?
Yes, the TPSMP30-E3/84A uses a color band to denote the cathode terminal, consistent with standard diode polarity conventions. The banded end must be connected toward the lower-potential side (e.g., ground) in unidirectional configurations. This marking is visible on the DO-220AA package body and verified in Vishay's mechanical drawings (Figure 5, Document 88937).
What is the moisture sensitivity level (MSL) rating for the TPSMP30-E3/84A?
The TPSMP30-E3/84A is rated MSL Level 1 per J-STD-020C, meaning it may be stored indefinitely at ≤30 °C/60 % RH without baking prior to reflow soldering. This eliminates pre-conditioning steps in SMT assembly and supports high-throughput automotive manufacturing lines.
