Product details
Overview
TPC9.1AHM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial surge protection. It features a 9.1 V nominal breakdown voltage (VBR), 7.78 V stand-off voltage (VWM), 13.4 V maximum clamping voltage (VC) at 50 A peak pulse current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the TPC9.1AHM3/86A datasheet, TPC9.1AHM3/86A pinout, TPC9.1AHM3/86A application, or TPC9.1AHM3/86A equivalent, key selection criteria include clamping performance at 50 A, 185 °C junction temperature rating, low-profile 1.1 mm height, unidirectional polarity, and compatibility with automated SMT placement on automotive-grade PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable breakdown behavior and low incremental surge resistance. Its junction passivation enables reliable operation up to TJ = 185 °C, meeting stringent automotive thermal requirements without derating at elevated ambient temperatures.
The device responds to transients within nanoseconds and clamps 10/1000 μs surges to ≤13.4 V at 50 A. It meets J-STD-020 MSL Level 1, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molding compound standards - all verified per the official Vishay document 89056.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VWM | 7.78 V - maximum continuous reverse voltage compatible with 5 V–8 V logic and sensor supply rails |
| VC @ IPPM | 13.4 V - clamping voltage at 50 A limits stress on protected MOSFETs or microcontrollers |
| PPPM | 1500 W - peak pulse power handling supports ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges |
| TJ max. | 185 °C - enables direct mounting near heat sources (e.g., engine control units) without thermal derating |
| Package | SMPC (TO-277A) - 3-pin surface-mount outline with cathode band marking and 1.1 mm profile for space-constrained layouts |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
TPC9.1AHM3/86A uses the SMPC (TO-277A) package: a 3-terminal, single-anode/two-cathode configuration with cathode band marking on terminal 1 and 2, and anode on terminal 3. The package measures 4.80 mm × 3.70 mm × 1.1 mm and is optimized for reflow soldering per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-biased cathode connection | Common cathode node shared with Pin 2; connects to protected line's positive rail or signal path |
| 2 (Cathode) | Reverse-biased cathode connection | Electrically tied to Pin 1 internally; provides dual-pad layout flexibility and enhanced current sharing |
| 3 (Anode) | Anode reference node | Connected to system ground or low-side return path; defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Stable VBR drift < ±5 % over 1000 hrs at 150 °C, ensuring long-term clamping consistency in harsh environments |
| Low profile (1.1 mm height) | Enables placement beneath connectors or in stacked modules where Z-axis clearance is limited to < 1.2 mm |
| MSL Level 1 rating | Zero floor life limitation - can be stored indefinitely at ≤30 °C/60 % RH without baking prior to reflow |
| Halogen-free & RoHS-compliant | Meets automotive ELV Directive and IPC-1752A material declaration requirements for Tier 1 supply chains |
| Matte tin-plated leads | Solderable per JESD 22-B102, eliminating post-reflow oxidation concerns and enabling lead-free SAC305 compatibility |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator ripple in engine compartments. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp transients above 7.78 V. Use Value: Clamps ISO 7637-2 Pulse 5a (100 V/500 ms) to ≤13.4 V, preventing brownout or latch-up in MCU power domains. | Use Scenario: Safeguarding analog front-ends of pressure/temperature sensors connected to CAN or LIN buses. IC Role / Device Role / Timing Role: Line-to-ground suppression on sensor signal lines exposed to ESD and cable discharge events. Use Value: Limits induced voltage spikes to <13.4 V during IEC 61000-4-2 ±8 kV contact discharge, preserving ADC input integrity. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feeds |

IC Role / Device Role / Timing Role: Unidirectional clamping device across output rail and GND to absorb capacitive coupling surges. Use Value: Withstands 1500 W peak pulses while maintaining VWM = 7.78 V, avoiding false triggering during normal 9 V operation. | Use Scenario: Protection of -48 V telecom power distribution boards against lightning-induced surges on outdoor feeder lines. IC Role / Device Role / Timing Role: Ground-referenced TVS on DC input bus to divert common-mode energy into chassis ground. Use Value: Delivers 13.4 V clamping at 50 A with 185 °C TJ rating, supporting extended operation in uncooled outdoor cabinets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Lower PPPM (400 W), SMA package (2.5 mm height), VC = 14.4 V @ 28.5 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select for cost-sensitive consumer designs where 1500 W rating and automotive qualification are unnecessary |
| TPC9.1AHM3_A | Same electrical specs and SMPC package; differs only in tape-and-reel packaging (H vs. 86A suffix denotes reel size and orientation) | No functional difference; identical performance and reliability | Choose based on assembly line feed requirements - 86A indicates 13" reel (6500 pcs), H indicates 7" reel (1500 pcs) |
Compared with SMAJ9.0A and TPC9.1AHM3_A, the TPC9.1AHM3/86A uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and 1.1 mm profile - making it the only option suitable for space-constrained, high-reliability automotive power nodes requiring validated lifetime performance at 185 °C.

FAQ
What is the exact breakdown voltage tolerance for TPC9.1AHM3/86A?
The TPC9.1AHM3/86A has a specified breakdown voltage (VBR) range of 8.65 V (min) to 9.55 V (max) at 1.0 mA test current, with 9.10 V as the nominal value. This ±5 % tolerance is confirmed in Vishay document 89056, Table 1, and applies across the full operating temperature range when adjusted using the stated temperature coefficient of 0.060 %/°C.
Is TPC9.1AHM3/86A compatible with lead-free reflow processes?
Yes, TPC9.1AHM3/86A features matte tin-plated terminals qualified per J-STD-002 and JESD 22-B102, supporting standard lead-free reflow profiles including peak temperatures up to 260 °C. Its MSL Level 1 rating eliminates floor life restrictions, and the SMPC package's thermal mass allows uniform heating without delamination or voiding.
Does TPC9.1AHM3/86A have a bidirectional variant?
No - TPC9.1AHM3/86A is unidirectional only, as explicitly stated in the Vishay datasheet. Bidirectional variants are not offered in the TPC6.8A–TPC51A family. For bidirectional protection, engineers must select alternate families such as the SMBJ or SMCJ series, which provide symmetric clamping but lack the 185 °C TJ rating and SMPC footprint of TPC9.1AHM3/86A.
What is the meaning of the "86A" suffix in TPC9.1AHM3/86A?
The "86A" suffix in TPC9.1AHM3/86A identifies the packaging configuration: it denotes a 13-inch diameter plastic tape-and-reel format containing 6500 units, with orientation and sprocket hole positioning compliant with EIA-481-D. This differs from the "H" suffix (e.g., TPC9.1AHM3_H), which specifies a 7-inch reel with 1500 units - both share identical electrical and mechanical specifications.
How does TPC9.1AHM3/86A perform under high-temperature operating conditions?
TPC9.1AHM3/86A maintains full rated performance up to TJ = 185 °C, with VBR shift calculated using αT = 0.060 %/°C. At 150 °C junction temperature, VBR increases by ~1.5 % versus 25 °C - well within its 8.65–9.55 V specification window. Derating curves in Figure 2 of document 89056 confirm no reduction in PPPM or IPPM below 185 °C.
