Product details
Overview
TPSMP8.2AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial overvoltage protection. It features a 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 300 W peak pulse power (10/1000 µs), 24.8 V clamping voltage at 200 A surge current, and AEC-Q101 qualification - deployed on signal lines of automotive sensor units and drive transistors.
For engineers reviewing the TPSMP8.2AHM3_A/H datasheet, TPSMP8.2AHM3_A/H pinout, TPSMP8.2AHM3_A/H application, or TPSMP8.2AHM3_A/H equivalent, key selection criteria include its DO-220AA (SMP) package, 185 °C junction rating, low-profile 1.0 mm height, unidirectional polarity with cathode band marking, and compliance with JESD201 Class 2 whisker testing.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve fast response time and low incremental surge resistance. Its junction passivation enables stable operation up to TJ = 185 °C, supporting under-hood automotive environments where thermal derating must be minimized.
The device operates exclusively in unidirectional mode and is rated for 10/1000 µs surge waveforms per IEC 61000-4-5 and ANSI/IEEE C62.35. Clamping performance is validated at IPPM = 200 A with VC ≤ 24.8 V, ensuring robust protection for 5 V–12 V logic interfaces without excessive voltage overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - ensures reliable triggering above system operating voltage while avoiding false trips during transients |
| VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 50 µA, compatible with 5 V–7 V signal rails |
| VC @ IPPM | 24.8 V @ 200 A - limits protected node voltage during 10/1000 µs surges, safeguarding downstream ICs |
| PPPM | 300 W - peak pulse power handling capability for automotive load-dump and ISO 7637-2 pulse 1/2/5a events |
| TJ max. | 185 °C - enables placement near heat sources (e.g., power modules) without derating penalties |
| Package | SMP (DO-220AA) - ultra-low profile (1.0 mm height), halogen-free, RoHS-compliant, MSL Level 1 |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
TPSMP8.2AHM3_A/H is a two-terminal surface-mount TVS diode in the SMP (DO-220AA) package. The cathode is marked by a color band; the anode is the opposite end. No internal circuitry or control pins exist - it functions as a passive bidirectional clamp only in reverse-biased configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-bias terminal | Connected to protected line; conducts when transient exceeds VBR, shunting surge to ground |
| Anode | Reference/ground return | Typically tied to system ground or low-impedance return path; completes clamping current loop |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Enables stable 185 °C operation and long-term reliability in thermally aggressive automotive environments |
| Low-profile SMP package | 1.0 mm typical height allows integration into space-constrained modules like ADAS camera ECUs and motor control PCBs |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced damage or popcorn effect |
| JESD201 Class 2 whisker resistance | Prevents tin whisker growth under thermal cycling, critical for safety-critical automotive applications |
| Unidirectional clamping | Optimized for DC-biased signal lines (e.g., CAN, LIN, sensor analog outputs) where forward conduction is not required |
Applications
| Automotive Sensor Protection | Industrial Motor Drive Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine control units exposed to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: TVS diode placed at sensor connector interface to clamp ESD and load-dump transients before they reach ADC inputs. Use Value: Prevents latch-up or permanent damage to 12-bit SAR ADCs by limiting transient voltage to ≤24.8 V during 200 A surges. | Use Scenario: Safeguarding gate driver signal traces between microcontroller and IGBT/MOSFET half-bridges in servo drives. IC Role / Device Role / Timing Role: Unidirectional TVS located adjacent to gate driver IC output pins to absorb Miller-induced spikes and cross-talk transients. Use Value: Maintains clean gate switching edges by suppressing >100 V transients within nanoseconds, reducing false turn-on risk. |
| Automotive Body Control Module | Consumer Power Adapter Input Stage |
Use Scenario: Overvoltage protection on LIN bus lines and LED driver control signals in door module ECUs. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 7.02 V) placed inline with 12 V supply-routed LIN transceivers. Use Value: Ensures uninterrupted communication during battery jump-start events (up to 24 V) while clamping 10/1000 µs surges to <25 V. | Use Scenario: Secondary-side transient suppression on 5 V USB-C PD output rails in compact wall adapters. IC Role / Device Role / Timing Role: Compact TVS mounted directly at USB port connector to meet IEC 61000-4-2 Level 4 ESD immunity. Use Value: Achieves 30 kV air/20 kV contact ESD protection in <1.0 mm height, enabling ultra-thin adapter designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher VBR (7.22–8.44 V), lower PPPM (400 W), SMA package (2.5 mm height) | Less suitable for space-constrained automotive modules due to taller profile and no AEC-Q101 certification | Select if cost sensitivity outweighs automotive qualification and board height constraints |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same PPPM (300 W), AEC-Q101 qualified, but larger SMA package | Not ideal for 7 V nominal systems requiring tighter margin between VWM and operating voltage | Choose only when VWM = 5.8 V is acceptable and PCB layout permits larger footprint |
Compared with SMAJ8.0A and TPSMA6.8A, TPSMP8.2AHM3_A/H delivers superior fit for automotive signal-line protection through its combination of AEC-Q101 qualification, DO-220AA low-profile packaging, precise 7.02 V standoff, and validated 24.8 V clamping - all in a single, production-ready tape-and-reel format.

FAQ
What is the exact breakdown voltage range specified for TPSMP8.2AHM3_A/H?
The TPSMP8.2AHM3_A/H has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent triggering behavior across production lots and temperature extremes, making it suitable for precision 7 V–8 V rail protection in automotive ECUs where margin to VWM (7.02 V) must remain stable.
Is TPSMP8.2AHM3_A/H qualified for automotive use?
Yes, TPSMP8.2AHM3_A/H is AEC-Q101 qualified and explicitly designated as automotive grade in Vishay's documentation. It passes stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), confirming suitability for under-hood and chassis-mounted applications where junction temperatures may reach 185 °C.
What does the "HM3_A/H" suffix indicate in TPSMP8.2AHM3_A/H?
The "HM3_A/H" suffix denotes the packaging and revision: HM3 indicates halogen-free, RoHS-compliant, AEC-Q101-qualified construction in DO-220AA (SMP) package; "A" is the revision code; "H" specifies 7″ diameter plastic tape-and-reel delivery with 3000 units per reel - a standard logistics configuration for SMT assembly lines.
How does the clamping voltage of TPSMP8.2AHM3_A/H compare to similar 8 V TVS diodes?
TPSMP8.2AHM3_A/H clamps to ≤24.8 V at 200 A (10/1000 µs), which is 1.2–1.8 V lower than comparable 8 V TVS devices in SMA packages (e.g., SMAJ8.0A clamps at 26.5 V). This lower VC directly improves system-level surge immunity by reducing stress on downstream 24 V-tolerant receivers and analog front-ends.
Can TPSMP8.2AHM3_A/H replace TPSMP8.2A in existing designs?
Yes, TPSMP8.2AHM3_A/H is a direct replacement for TPSMP8.2A - both share identical electrical characteristics, SMP package dimensions, and AEC-Q101 qualification. The "HM3_A/H" variant adds halogen-free and enhanced whisker resistance (JESD201 Class 2), making it preferred for new automotive designs requiring stricter material compliance.
