Product details
Overview
TPSMP10AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial overvoltage protection. It features 9.5 V minimum / 10.5 V maximum breakdown voltage at 1 mA, 8.55 V stand-off voltage, 14.5 V clamping voltage at 20 A peak pulse current, and 300 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the TPSMP10AHM3/84A datasheet, TPSMP10AHM3/84A pinout, TPSMP10AHM3/84A application, or TPSMP10AHM3/84A equivalent, this device is selected for robust ESD and surge protection in low-voltage signal lines, automotive sensor interfaces, and power rail clamping where AEC-Q101 qualification, 185 °C junction temperature capability, and ultra-low profile (1.0 mm height) are critical.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD transients per IEC 61000-4-2 and electrical fast transients per IEC 61000-4-4. Its unidirectional polarity and cathode band marking align with standard PCB layout conventions for reverse-biased protection.
The device operates within -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its 2.5 W steady-state power dissipation and 40 A non-repetitive forward surge current support sustained operation under intermittent overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 9.5 V min / 10.5 V max at 1 mA - defines precise conduction threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 8.55 V - ensures no leakage or false triggering during normal 8 V nominal rail operation |
| Clamping Voltage VC | 14.5 V at 20 A IPPM - limits downstream IC voltage stress during 10/1000 μs surge events |
| Peak Pulse Power PPPM | 300 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 extended industrial thermal environments |
| AEC-Q101 Qualified | Yes - certified for automotive electronic systems requiring zero-defect reliability and stress testing compliance |

Applications
| Automotive Sensor Interface Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to ISO 7637-2 pulses and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller input to clamp transients before they reach ADC or UART pins. Use Value: 14.5 V clamping at 20 A prevents latch-up or damage to 5 V tolerant MCU I/O while maintaining signal integrity below 8.55 V operating range. |
Use Scenario: Safeguarding 24 V DC digital input channels on programmable logic controllers against field-wiring surges and inductive kickback. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across input optocoupler terminals to absorb repetitive 100 V/1 A transients without degradation. Use Value: 300 W peak pulse power and -65 °C to +185 °C operation ensure uninterrupted function in factory-floor environments with wide ambient swings. |
| Consumer USB Port ESD Protection | DC-DC Converter Feedback Line Clamping |
Use Scenario: Adding secondary ESD protection on USB 2.0 data lines (D+/D-) in portable medical devices where primary protection resides upstream. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. 100 pF at 0 V) placed directly at connector to shunt >8 kV HBM discharges before reaching PHY transceiver. Use Value: Fast response time (<1 ns) and 14.5 V clamping prevent data corruption or PHY reset during clinical handling events. |
Use Scenario: Securing voltage feedback node of isolated 12 V → 3.3 V flyback converter in telecom power supplies against coupling-induced transients. IC Role / Device Role / Timing Role: Precision-clamping TVS referenced to local ground to limit feedback voltage excursion and avoid erroneous regulation or OVP shutdown. Use Value: Tight 9.5–10.5 V VBR tolerance ensures clamping activates only above nominal 8.55 V feedback level, preserving regulation accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package; 10 V VBR (min/max 9.0–11.1 V); 400 W PPPM; 17.1 V VC at 24.7 A | Larger footprint (2.79 mm height) and lower thermal mass; less suitable for dense automotive modules | Select when higher peak power margin is required and board space allows larger package |
| TPSMA6.8A | Same DO-220AA package; lower 6.8 V VBR (6.45–7.14 V); 250 W PPPM; 10.5 V VC at 20 A | Designed for 5 V systems; insufficient clamping headroom for 12 V automotive rails | Choose only for sub-8 V signal line protection where tighter VBR alignment is mandatory |
Compared with SMAJ10A and TPSMA6.8A, the TPSMP10AHM3/84A delivers optimal balance of compact DO-220AA form factor, AEC-Q101 qualification, and 300 W surge capacity tailored for 12 V automotive domains-making it preferred for space-constrained, high-reliability ECU designs where thermal and mechanical robustness are non-negotiable.

FAQ
What is the exact breakdown voltage range for TPSMP10AHM3/84A?
The TPSMP10AHM3/84A has a guaranteed breakdown voltage range of 9.5 V minimum to 10.5 V maximum at 1 mA test current, as specified in the Vishay datasheet revision 22-Jul-16. This ±5 % tolerance ensures consistent turn-on behavior across production lots and temperature extremes, critical for predictable clamping in 12 V automotive systems where the TPSMP10AHM3/84A is commonly deployed.
Is TPSMP10AHM3/84A suitable for bidirectional signal line protection?
No, the TPSMP10AHM3/84A is strictly unidirectional and must be used with correct polarity-cathode connected to the reference rail (e.g., ground or positive supply). It does not provide symmetrical clamping for AC-coupled or differential signals. For bidirectional protection, a dedicated bidirectional TVS such as the SMBJ10CA would be required instead of the TPSMP10AHM3/84A.
Does TPSMP10AHM3/84A meet automotive qualification standards?
Yes, the TPSMP10AHM3/84A is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature, making it suitable for under-hood and transmission-control applications. Its halogen-free, RoHS-compliant construction and MSL Level 1 reflow rating further satisfy automotive manufacturing and environmental requirements-key attributes confirmed for the TPSMP10AHM3/84A in Vishay's official documentation.
What is the clamping voltage of TPSMP10AHM3/84A at its rated surge current?
The TPSMP10AHM3/84A clamps to a maximum of 14.5 V at 20 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during surge events-directly supporting the TPSMP10AHM3/84A's role in safeguarding 5 V and 3.3 V logic interfaces fed from 12 V rails.
Can TPSMP10AHM3/84A be used in place of TPSMP10 without modification?
Yes, the TPSMP10AHM3/84A replaces the standard TPSMP10 with tighter ±5 % VBR tolerance (9.5–10.5 V vs. 9.0–11.0 V), identical DO-220AA package, and same AEC-Q101 qualification. No PCB layout change is needed, but the improved tolerance enhances design margin in precision clamping applications-making the TPSMP10AHM3/84A a drop-in upgrade where tighter VBR control is beneficial.
