Product details
Overview
TPSMP36AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial circuit protection. It features 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 52.0 V clamping voltage (VC) at 8.0 A peak pulse current, and 400 W peak pulse power rating - optimized for protecting sensor signal lines and drive transistors against ESD and surge events.
For engineers reviewing the TPSMP36AHM3/84A datasheet, TPSMP36AHM3/84A pinout, TPSMP36AHM3/84A application, or TPSMP36AHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and uni-directional polarity with cathode band marking - all critical for under-hood automotive electronics and space-constrained PCB layouts.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver fast response time (<1 ns), low incremental surge resistance, and excellent clamping capability under 10/1000 μs surge waveforms. Its unidirectional configuration enables integration into DC-biased signal paths where reverse conduction must be blocked while suppressing positive transients.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM). Its DO-220AA package supports automated placement and meets UL 94 V-0 flammability requirements, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines minimum and maximum voltage at which device enters avalanche breakdown under 1 mA test current; ensures consistent overvoltage triggering across production lot |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets safe DC bias margin for protected line |
| VC @ IPPM | 52.0 V @ 8.0 A - clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs during transient event |
| PPPM | 400 W - peak pulse power handling capacity; enables robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |
| IFSM | 40 A - peak forward surge current rating for 10 ms half-sine waveform; supports resilience against load dump and inductive switching events |
| TJ max | +185 °C - maximum junction temperature; qualifies device for under-hood automotive applications per AEC-Q101 Grade 0 |
| Package | DO-220AA (SMP) - ultra-low profile surface-mount package with 1.0 mm typical height; enables dense layout and compatibility with standard SMT reflow profiles |
Pinout & Package
TPSMP36AHM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) package. Polarity is marked by a color band indicating the cathode terminal. The device has no active pins - only anode and cathode terminals mounted on PCB copper pads (5.0 mm × 5.0 mm per terminal recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge | Connected to protected line's lower-potential side (e.g., GND or return path); conducts during positive transients when cathode is at higher potential |
| Cathode | Reverse-biased terminal during normal operation | Marked with color band; connected to protected line's higher-potential side (e.g., signal or supply rail); blocks DC current but avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for engine control, ADAS, and body electronics |
| 185 °C junction rating | Enables operation in high-ambient environments such as powertrain modules without derating or thermal throttling |
| 1.0 mm typical height | Reduces board real estate and improves airflow in stacked or enclosed assemblies; compatible with low-clearance enclosures |
| MSL Level 1 (260 °C peak) | Eliminates pre-bake requirement prior to reflow soldering; simplifies manufacturing and reduces process risk |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin for sensitive CMOS inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/61 | DO-214AC (SMA) package; 36 V VBR min/max = 40.0–44.2 V; 400 W PPPM; 1.9 mm height | Higher profile and larger footprint; less suitable for ultra-thin automotive modules | Select when legacy SMA footprint compatibility is required and board height budget allows ≥1.9 mm |
| 1.5SMC36A | DO-214AB (SMC) package; 36 V VBR min/max = 40.0–44.2 V; 1500 W PPPM; 2.6 mm height | Higher power rating but significantly larger size; intended for primary-level AC/DC input protection | Choose for front-end AC mains or DC bus protection where space permits and >400 W surge handling is mandatory |
Compared with SMAJ36A-E3/61 and 1.5SMC36A, TPSMP36AHM3/84A offers the lowest profile (1.0 mm) and smallest footprint in its 400 W class, making it optimal for space-constrained, high-temperature automotive signal-line protection - whereas alternatives trade compactness for legacy package compatibility or higher power handling.

FAQ
What is the breakdown voltage range for TPSMP36AHM3/84A?
The TPSMP36AHM3/84A has a specified breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1 mA test current, as confirmed in the Vishay datasheet Document Number 88471, Table on page 2. This range ensures predictable avalanche initiation across temperature and process variation, and directly supports its use in 24 V automotive systems where 30.8 V stand-off voltage provides adequate margin above nominal rail.
Is TPSMP36AHM3/84A suitable for automotive applications?
Yes, TPSMP36AHM3/84A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood automotive applications including engine control units, ADAS camera modules, and body control modules. Its DO-220AA package, MSL Level 1 rating, and halogen-free construction meet automotive manufacturing and reliability requirements as documented in Vishay's official specification.
What is the clamping voltage of TPSMP36AHM3/84A at its rated peak pulse current?
The clamping voltage (VC) of TPSMP36AHM3/84A is 52.0 V at 8.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 and Table on page 2 of the Vishay datasheet 88471 and defines the maximum voltage seen by protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does TPSMP36AHM3/84A have bidirectional or unidirectional polarity?
TPSMP36AHM3/84A is a unidirectional TVS diode, as explicitly stated in the "FEATURES" section of the Vishay datasheet (page 1). It conducts only during positive transients applied to its cathode relative to anode, and blocks reverse current during normal operation - requiring correct orientation on PCB with cathode band aligned to the higher-potential side of the protected line.
What package type does TPSMP36AHM3/84A use, and what are its key mechanical attributes?
TPSMP36AHM3/84A uses the DO-220AA (SMP) package, with mechanical dimensions detailed on page 4 of Vishay document 88471. Key attributes include 1.0 mm typical height, 0.142 inch (3.61 mm) body length, cathode band marking, matte tin-plated leads, and UL 94 V-0 molding compound - all supporting automated SMT assembly and high-reliability deployment in thermally demanding environments.
