Product details
Overview
TPSMP30HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 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), and clamps to ≤43.5 V at rated surge - used in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the TPSMP30HM3/84A datasheet, TPSMP30HM3/84A pinout, TPSMP30HM3/84A application, or TPSMP30HM3/84A 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 and space-constrained industrial PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive surge stress. Its unidirectional architecture enables integration into DC-biased signal paths without forward conduction interference, and its low incremental surge resistance ensures minimal voltage overshoot during fast transients.
The device operates across –65 °C to +185 °C and maintains specified clamping performance up to 150 °C junction temperature. Its 10/1000 µs waveform response time is sub-nanosecond, and it meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 27.0 V min / 33.0 V max at 1.0 mA - defines precise turn-on threshold for overvoltage triggering |
| Stand-off Voltage VWM | 24.3 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA |
| Clamping Voltage VC | ≤43.5 V at 9.2 A IPPM - limits protected circuit voltage during 10/1000 µs surge |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - sustains high-energy transients without failure in automotive load-dump scenarios |
| Junction Temperature Range | –65 °C to +185 °C - supports under-hood automotive placement and industrial thermal cycling |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements |
| Package | DO-220AA (SMP) - 1.0 mm typical height, halogen-free, RoHS-compliant, MSL Level 1 |
Pinout & Package
TPSMP30HM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) surface-mount package. Cathode is marked by a color band on the body; anode and cathode terminals are symmetrically arranged for automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse bias reference | Connected to lower-potential side of protected line; enables DC blocking in reverse mode |
| Cathode | Clamping node / Surge current sink | Connected to higher-potential side; conducts surge current to ground when VBR exceeded |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier technology | Enables stable VBR tolerance and low leakage (<1.0 μA at VWM) across temperature and life cycle |
| 185 °C maximum junction temperature | Supports operation in engine compartment and industrial control enclosures without derating |
| 1.0 mm typical package height | Reduces board profile for tight stacking in automotive ECUs and portable industrial sensors |
| MSL Level 1 (260 °C peak) | Allows single-pass lead-free reflow without moisture sensitivity concerns |
| Matte tin-plated leads | Ensures reliable solder joint formation per J-STD-002 and JESD22-B102 |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ISO 7637-2 pulses and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between signal line and ground, triggered only during positive transients relative to reference. Use Value: Clamps 43.5 V at 9.2 A while maintaining <1.0 μA leakage at 24.3 V - preserving signal integrity and minimizing standby power loss. |
Use Scenario: Safeguarding PLC digital input modules against induced surges from relay coil flyback and AC line coupling. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input channels, absorbing energy before reaching optocoupler or MCU GPIO. Use Value: 400 W peak pulse power rating handles repeated 10/1000 µs transients without degradation - extending field service life in factory automation. |
| Consumer Power Adapter Input | Motor Drive Gate Protection |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and AC/DC SMPS output rails. IC Role / Device Role / Timing Role: Unidirectional clamp on regulated 5–20 V output, preventing damage to downstream USB controllers during fault conditions. Use Value: 24.3 V stand-off voltage allows safe operation across full USB PD voltage range while clamping to ≤43.5 V - meeting IEC 61000-4-5 Level 3 immunity. |
Use Scenario: Protecting high-side gate drivers in BLDC motor inverters from Miller-induced voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Fast-response TVS across gate-source terminals to clamp dv/dt-induced overshoot before MOSFET threshold violation. Use Value: Sub-nanosecond response and low clamping impedance limit gate voltage excursion to <43.5 V - preventing unintended turn-on and shoot-through. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC (SMA) package; 30 V VBR; 400 W PPPM; 1.5 mm height; no AEC-Q101 qualification | Larger footprint and height; suitable for non-automotive industrial use where space is less constrained | Select SMAJ30A if board layout permits larger package and AEC-Q101 is not required |
| TPSMAJ30A | DO-214AC (SMA) package; same electrical specs; AEC-Q101 qualified; 1.5 mm height; halogen-free | Same automotive qualification but 50% taller - may interfere with adjacent components or shield cans | Choose TPSMAJ30A only when DO-220AA footprint is incompatible with existing assembly tooling |
Compared with SMAJ30A and TPSMAJ30A, TPSMP30HM3/84A delivers identical 30 V clamping performance in a 1.0 mm profile DO-220AA package with AEC-Q101 validation - enabling denser layouts and certified automotive deployment without height penalty.

FAQ
What is the exact breakdown voltage range for TPSMP30HM3/84A?
The TPSMP30HM3/84A has a guaranteed breakdown voltage (VBR) range of 27.0 V to 33.0 V at 1.0 mA test current, per the Vishay datasheet revision 22-Jul-16. This tolerance reflects the ±10 % specification for the "non-A" variant, and the value is measured after 300 µs square-wave pulse application per ANSI/IEEE C62.35 standards.
Is TPSMP30HM3/84A suitable for bidirectional signal line protection?
No - TPSMP30HM3/84A is strictly unidirectional and must be used only in DC-biased circuits where reverse conduction is acceptable. For bidirectional protection (e.g., USB data lines or RS-485), a symmetrical TVS like SMBJ33CA or a dedicated bidirectional array is required; using TPSMP30HM3/84A in AC-coupled paths risks forward conduction and signal distortion.
Does TPSMP30HM3/84A meet automotive qualification standards?
Yes - TPSMP30HM3/84A is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number 88471). It undergoes stress testing including HTGB, HTRB, TCT, and mechanical shock per AEC-Q101 Rev D, and carries the HM3 suffix denoting halogen-free, RoHS-compliant, and automotive-grade construction.
What is the maximum clamping voltage of TPSMP30HM3/84A at rated surge current?
The maximum clamping voltage (VC) of TPSMP30HM3/84A is 43.5 V at 9.2 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured with the device mounted on a PCB having 5.0 mm × 5.0 mm copper pads per terminal, as defined in the Vishay test setup.
Can TPSMP30HM3/84A be used in lead-free reflow processes?
Yes - TPSMP30HM3/84A is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the molding compound meets UL 94 V-0 flammability rating - making it fully compatible with standard lead-free SMT assembly.
