Product details
Overview
TPSMP16-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade surge protection. It features a breakdown voltage range of 14.4 V to 17.6 V at 1 mA test current, 1.0 W steady-state power dissipation, 40 A peak forward surge current, and clamps transients up to 23.5 V at 17.0 A (10/1000 µs waveform). It is used to protect sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP16-E3/84A datasheet, TPSMP16-E3/84A pinout, TPSMP16-E3/84A application, or TPSMP16-E3/84A equivalent, key selection criteria include its 1.0 mm profile, AEC-Q101-compliant commercial-grade qualification (E3 suffix), 185 °C max junction temperature, and low incremental surge resistance enabling robust ESD and load-dump immunity in space-constrained PCB layouts.
Technical Context
The TPSMP16-E3/84A operates as a unidirectional avalanche diode with a color-band cathode marking, utilizing Vishay's patented PAR oxide passivated chip construction for stable clamping and low leakage. Its electrical behavior follows ANSI/IEEE C62.35 standards, with breakdown voltage specified at 300 µs square-wave pulse and clamping defined per 10/1000 µs waveform.
Thermal performance is rated for operation from –65 °C to +185 °C, with power derating above 25 °C ambient per Figure 2. Mounting on 5.0 × 5.0 mm copper pads is required to achieve the full 400 W peak pulse power rating (per V(BR) 13–43 V group), and it meets MSL Level 1 per J-STD-020C with 260 °C solder dip tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 14.4 V min / 17.6 V max at 1 mA - defines minimum trigger threshold and maximum variation under production tolerance |
| Stand-off Voltage VWM | 12.9 V - maximum continuous reverse voltage before significant leakage begins; sets operating margin below V(BR) |
| Clamping Voltage VC | 23.5 V at IPPM = 17.0 A (10/1000 µs) - limits transient voltage seen by protected IC during surge events |
| Peak Pulse Power PPPM | 400 W - energy-handling capacity for short-duration transients such as ISO 7637-2 load dump pulses |
| Peak Forward Surge Current IFSM | 40 A - withstands single half-sine surges up to 10 ms, critical for automotive alternator-induced spikes |
| Junction Temperature Range | –65 °C to +185 °C - supports under-hood automotive environments without thermal derating loss |
Pinout & Package
Package: DO-220AA (SMP), ultra-low-profile surface-mount case with 1.0 mm typical height, matte tin-plated terminals, UL-94V-0 epoxy, and cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during surge conduction | Connected to protected line (e.g., sensor output); conducts when transient exceeds V(BR) |
| Cathode | Reverse-biased terminal; marked with color band | Connected to ground or lower-potential rail; establishes unidirectional clamping polarity |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable, repeatable avalanche characteristics over lifetime and temperature, reducing parameter drift in automotive duty cycles |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD), improving clamping precision beyond standard TVS specs |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility without dry-pack requirements-reduces manufacturing overhead |
| 1.0 mm profile | Enables placement in tight spaces near connectors or sensors where board height is constrained (e.g., ADAS camera modules) |
Applications
| Automotive Sensor Protection | Power Line Transient Suppression |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine control units exposed to ISO 7637-2 pulses and ESD. IC Role / Device Role: Unidirectional clamping diode placed between sensor output and ground. Use Value: Limits transient voltage to ≤23.5 V while maintaining <1 µA leakage at 12.9 V, preserving sensor accuracy and MCU ADC integrity. | Use Scenario: Safeguarding 12 V supply rails feeding microcontrollers and CAN transceivers against load dump and jump-start surges. IC Role / Device Role: Primary TVS on main power input, upstream of LDO or DC-DC converter. Use Value: Absorbs up to 400 W peak power without failure, preventing latch-up or burnout in downstream ICs during 12 V system transients. |
| Industrial Motor Drive Interface | Consumer Appliance Control Board |
Use Scenario: Shielding gate driver signal traces and feedback lines in BLDC motor controllers from switching noise and inductive kickback. IC Role / Device Role: Point-of-load TVS on PWM input and current-sense amplifier inputs. Use Value: Fast response time and low clamping voltage ensure clean signal integrity during high-dV/dt commutation events. | Use Scenario: Protecting touch panel interfaces and microcontroller I/O pins in smart home appliances subjected to user ESD and mains-coupled noise. IC Role / Device Role: Secondary-level ESD clamp on USB, button, or display interface lines. Use Value: Meets IEC 61000-4-2 Level 4 (±8 kV contact) with minimal board area due to DO-220AA footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5AT | DO-214AC (SMA) package; 16 V nominal V(BR); 400 W PPPM; higher profile (2.29 mm) | Less suitable for ultra-low-height automotive modules; same clamping (25.5 V) but larger footprint | Select when legacy SMA layout exists and height constraint is relaxed |
| TPSMP16A-E3/84A | Tighter V(BR) tolerance (15.2–16.8 V vs. 14.4–17.6 V); identical package and thermal specs | Better voltage consistency for precision clamping; preferred where tighter V(BR) distribution reduces design margin risk | Select for new designs requiring improved parametric yield and reduced V(BR) spread |
Compared with SMAJ16A-E3/5AT, TPSMP16-E3/84A saves >55 % board height and offers superior surge resistance; compared with TPSMP16A-E3/84A, it trades tighter V(BR) control for broader availability and cost efficiency in volume automotive programs.

FAQ
What is the exact breakdown voltage range for TPSMP16-E3/84A?
The TPSMP16-E3/84A has a guaranteed breakdown voltage (V(BR)) range of 14.4 V to 17.6 V at 1 mA test current, measured after a 300 µs square-wave pulse per ANSI/IEEE C62.35. This range reflects production tolerance and ensures reliable triggering across temperature and lifetime. The TPSMP16-E3/84A datasheet specifies this value in Table 1 under "ELECTRICAL CHARACTERISTICS".
Is TPSMP16-E3/84A qualified for automotive use?
Yes, TPSMP16-E3/84A carries the E3 suffix indicating Vishay's commercial-grade qualification, which includes full AEC-Q101 stress testing for transient voltage suppressors. It is rated for operation from –65 °C to +185 °C and meets MSL Level 1 per J-STD-020C-making it suitable for under-hood automotive applications. The TPSMP16-E3/84A is explicitly listed in Vishay's automotive-grade TVS portfolio.
What does the "84A" in TPSMP16-E3/84A indicate?
The "84A" in TPSMP16-E3/84A is Vishay's preferred package code denoting 7-inch diameter plastic tape-and-reel packaging with a base quantity of 3000 units. It is not a performance variant-it identifies the delivery format and matches the mechanical dimensions and electrical specs of all TPSMP16-E3 variants. The TPSMP16-E3/84A shares identical electrical characteristics with TPSMP16-E3/85A (10,000-unit reel).
How does TPSMP16-E3/84A compare to TPSMP16A-E3/84A?
TPSMP16-E3/84A has a wider V(BR) range (14.4–17.6 V) versus TPSMP16A-E3/84A (15.2–16.8 V), offering broader availability and cost advantage; both share identical DO-220AA package, 400 W PPPM rating, 23.5 V clamping, and AEC-Q101 qualification. The TPSMP16-E3/84A is the standard version used where tighter V(BR) tolerance is not required.
What is the maximum clamping voltage of TPSMP16-E3/84A under surge conditions?
The maximum clamping voltage (VC) of TPSMP16-E3/84A is 23.5 V at a peak pulse current (IPPM) of 17.0 A using the standardized 10/1000 µs waveform. This value is measured at TJ = 25 °C with proper PCB mounting (5.0 × 5.0 mm copper pads per terminal). The TPSMP16-E3/84A maintains this clamping performance across its full operating temperature range.
