Product details
Overview
TPSMP16HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial surge protection. It features 16 V breakdown voltage (VBR min/max = 14.4 V / 17.6 V), 400 W peak pulse power (10/1000 µs), 17.0 A peak pulse current (IPPM), and clamps to 23.5 V at rated surge. Used to protect signal lines and drive transistors in automotive ECUs and sensor interfaces.
For engineers reviewing the TPSMP16HM3/84A datasheet, TPSMP16HM3/84A pinout, TPSMP16HM3/84A application, or TPSMP16HM3/84A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction rating, low-profile 1.0 mm height, and MSL Level 1 reflow compatibility - all critical for under-hood automotive PCB designs requiring robust ESD and lightning surge immunity.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of EFT, ESD, and ISO 7637-2 transients. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<1 µA at VWM = 12.9 V).
Thermal design leverages a 185 °C maximum junction temperature and 2.5 W steady-state power dissipation on infinite heatsink, with derating above 75 °C. The DO-220AA package supports automated placement and meets UL 94 V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.4 V / 17.6 V - defines reliable turn-on threshold across temperature and production lot; ensures clamping initiates before downstream IC damage. |
| VWM | 12.9 V - maximum continuous reverse operating voltage; must exceed system nominal rail (e.g., 12 V automotive) with margin. |
| IPPM | 17.0 A - peak surge current capability under 10/1000 µs waveform; determines survivability against ISO 16750-2 Pulse 5a/b. |
| VC @ IPPM | 23.5 V - clamping voltage at rated surge; directly limits stress on protected IC's absolute maximum ratings. |
| PPPM | 400 W - peak pulse power handling (10/1000 µs); enables protection of higher-energy transients without thermal runaway. |
| TJ max | +185 °C - extended junction temperature rating; supports under-hood placement and long-term reliability in automotive environments. |
| Leakage @ VWM | <1 µA - ultra-low reverse leakage preserves battery life in always-on circuits and avoids false triggering. |
Pinout & Package
DO-220AA (SMP) surface-mount package: 2-terminal device with cathode indicated by color band; 1.0 mm typical height, 2.67 mm length, 1.88 mm width; halogen-free, RoHS-compliant, AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry during clamping | Connected to protected line (e.g., CAN_H); conducts surge energy to ground when VAK exceeds VBR. |
| Cathode | Reference terminal (marked with band) | Connected to system ground; establishes unidirectional clamping direction and defines VWM/VBR reference point. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| 185 °C junction rating | Enables operation in high-ambient under-hood locations without derating penalties up to +125 °C ambient. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without moisture sensitivity concerns or baking requirements. |
| Low-profile 1.0 mm height | Reduces board-level mechanical stress during thermal cycling and enables use in space-constrained modules. |
| Passivated anisotropic rectifier | Delivers stable VBR tolerance (±5 % for 'A' variants; TPSMP16HM3/84A is non-A variant, ±10 %) and low dynamic impedance. |
Applications
| Automotive Sensor Interface | Industrial CAN Bus Node |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor output and microcontroller ADC input. Use Value: Limits transient-induced ADC saturation and prevents latch-up by clamping to 23.5 V while drawing only 1 µA leakage at 12.9 V stand-off. | Use Scenario: Safeguarding CAN_H/CAN_L differential pair in factory automation PLC I/O modules subject to EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: Discrete TVS pair (one per line) referenced to chassis ground, leveraging fast <1 ns response to suppress sub-microsecond noise. Use Value: Maintains CAN signal integrity by limiting overshoot to ≤23.5 V without adding capacitance (>100 pF) that would distort 1 Mbps bit timing. |
| Consumer Power Adapter Input | Industrial Motor Drive Gate Driver |
Use Scenario: Secondary-side DC bus protection in USB-C PD adapters against surges induced by hot-plug or shared ground bounce. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12–20 V output rail upstream of DC-DC converter and load switch. Use Value: Absorbs 400 W pulses without degradation, ensuring no secondary failure mode during repeated 10/1000 µs surges per IEC 61000-4-5. | Use Scenario: Overvoltage protection for high-side gate driver supply (VB) in 3-phase inverter modules subjected to Miller-induced spikes. IC Role / Device Role / Timing Role: Clamp between VB and COM, triggered by dV/dt exceeding 14.4 V to prevent gate oxide rupture. Use Value: Withstands 17.0 A surge current and clamps within 23.5 V, preserving SiC MOSFET gate integrity during switching transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | DO-214AC (SMA) package; 16 V VBR; 400 W PPPM; 17.1 A IPPM; 25.0 V VC; 150 °C TJ max | Larger footprint (4.5 × 2.7 mm vs. 2.67 × 1.88 mm); lower thermal limit; not AEC-Q101 qualified | Select for cost-sensitive industrial designs where automotive qualification and miniaturization are not required. |
| TPSMAJ16A | Same DO-214AC package as SMAJ16A-E3/57T; identical electrical specs but Vishay-branded; AEC-Q101 option available in TPSMAJ16A-Q | No automotive qualification in standard version; requires Q-suffix part for AEC compliance | Choose TPSMAJ16A-Q if AEC-Q101 is mandatory but DO-220AA size is not; otherwise TPSMP16HM3/84A offers superior power density. |

FAQ
What is the breakdown voltage tolerance for TPSMP16HM3/84A?
The TPSMP16HM3/84A has a breakdown voltage range of 14.4 V to 17.6 V at 1.0 mA test current, corresponding to a ±10 % tolerance. This is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88471, where TPSMP16 (non-A suffix) is specified with min/max VBR values matching this spread. The 'A' variant (e.g., TPSMP16A) offers tighter ±5 % tolerance.
Is TPSMP16HM3/84A suitable for bidirectional transient protection?
No, TPSMP16HM3/84A is strictly unidirectional. Its datasheet explicitly states "Uni-direction only" under Features and lists polarity as cathode-band-marked. For bidirectional protection, a dual-diode configuration or dedicated bidirectional TVS (e.g., TPSMD16H) is required - TPSMP16HM3/84A cannot be used in AC-coupled or symmetrical surge scenarios without external circuitry.
Does TPSMP16HM3/84A meet automotive qualification standards?
Yes, TPSMP16HM3/84A is AEC-Q101 qualified, as stated in the Features section and reinforced by the "Base P/NHM3 - halogen-free, RoHS-compliant, and AEC-Q101 qualified" note in the Mechanical Data section. This qualification covers stress tests including HTGB, H3TRB, and temperature cycling, validating its suitability for automotive powertrain and body electronics.
What is the maximum clamping voltage of TPSMP16HM3/84A at its rated surge current?
The maximum clamping voltage (VC) of TPSMP16HM3/84A is 23.5 V at 17.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is specified in the Electrical Characteristics table on page 2 of Vishay document 88471 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can TPSMP16HM3/84A be used in lead-free reflow processes without baking?
Yes, TPSMP16HM3/84A meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, meaning it can undergo standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020) without prior baking or dry-pack requirements. This is explicitly noted in the Features list and confirmed in the Mechanical Data section.
