Product details
Overview
TPSMP36-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage protection. It features a breakdown voltage range of 32.4 V to 39.6 V at 1 mA test current, clamps to ≤52.0 V at 7.7 A peak pulse current (10/1000 µs), and delivers 400 W peak pulse power with 1.0 W steady-state power dissipation - used to safeguard sensor signal lines and drive transistors in engine control units.
For engineers reviewing the TPSMP36-E3/84A datasheet, TPSMP36-E3/84A pinout, TPSMP36-E3/84A application, or TPSMP36-E3/84A equivalent, key selection criteria include its AEC-Q101-compliant unidirectional clamping behavior, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity rating, and 185 °C maximum junction temperature for under-hood automotive deployment.
Technical Context
The TPSMP36-E3/84A employs Vishay's patented PAR oxide-passivated silicon chip construction, enabling low incremental surge resistance and fast response time to transient events. Its unidirectional configuration supports DC-biased signal line protection where reverse polarity is defined and controlled.
Rated for operation from –65 °C to +185 °C, it maintains stable clamping performance across automotive thermal extremes. The device meets J-STD-020C MSL Level 1 and withstands solder dip at 260 °C for 40 seconds, ensuring robustness in high-reliability SMT assembly processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 32.4 V min to 39.6 V max at 1 mA - defines minimum voltage at which clamping initiates under controlled DC stress |
| Stand-off Voltage VWM | 29.1 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| Clamping Voltage VC | ≤52.0 V at IPPM = 7.7 A (10/1000 µs) - limits transient-induced voltage seen by protected IC or transistor |

FAQ
What is the clamping voltage of the TPSMP36-E3/84A at its rated peak pulse current?
The TPSMP36-E3/84A clamps to a maximum of 52.0 V at 7.7 A peak pulse current using the standard 10/1000 µs waveform. This value is measured under defined test conditions per ANSI/IEEE C62.35 and ensures predictable voltage limiting for protected downstream circuitry such as microcontroller I/O or analog sensor inputs. The TPSMP36-E3/84A maintains this clamping performance across its specified operating temperature range.
Is the TPSMP36-E3/84A qualified for automotive applications?
Yes, the TPSMP36-E3/84A carries the E3 suffix indicating commercial-grade AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), confirming suitability for automotive powertrain and chassis systems. The TPSMP36-E3/84A is rated for continuous operation from –65 °C to +185 °C junction temperature.
What package type does the TPSMP36-E3/84A use, and what are its key mechanical attributes?
The TPSMP36-E3/84A uses the DO-220AA (SMP) package - a low-profile surface-mount case with 1.0 mm typical height, 0.142 inch (3.61 mm) length, and 0.086 inch (2.18 mm) width. Its matte tin-plated leads comply with J-STD-002B, and the epoxy meets UL-94V-0 flammability rating. The cathode is marked by a visible color band, and the device is MSL Level 1 per J-STD-020C.
How does the TPSMP36-E3/84A differ from the TPSMP36A-E3/84A variant?
The TPSMP36-E3/84A has a broader breakdown voltage range (32.4–39.6 V) versus the TPSMP36A-E3/84A (34.2–37.8 V), reflecting looser initial V(BR) tolerance. Both share identical DO-220AA packaging, 400 W peak pulse power, and AEC-Q101 qualification. The TPSMP36A-E3/84A is preferred where tighter V(BR) control is needed for precision analog protection, while the TPSMP36-E3/84A offers broader binning flexibility for cost-sensitive volume production.
What is the maximum steady-state power dissipation for the TPSMP36-E3/84A?
The TPSMP36-E3/84A has a maximum steady-state power dissipation (PD) of 1.0 W at TA = 50 °C on an infinite heatsink. Derating applies above 50 °C ambient, following the curve in Figure 6 of the datasheet. This rating supports continuous operation in thermally managed automotive modules, and the device's 185 °C maximum junction temperature allows integration near heat sources when PCB copper area and airflow are optimized.
