Product details
Overview
TPC11CAHM3/I from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in the SMPC (TO-277A) package, designed for high-reliability automotive and industrial electronics protection. It features a standoff voltage of 9.4 V, breakdown voltage of 10.5–11.6 V at 1 mA, clamping voltage of 15.6 V at 96.2 A, and operates from −65 °C to +185 °C.
For engineers reviewing the TPC11CAHM3/I datasheet, TPC11CAHM3/I pinout, TPC11CAHM3/I application, or TPC11CAHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, 1.1 mm profile for space-constrained PCBs, low leakage (<5 µA), fast response time, and suitability for protecting MOSFETs, sensor signal lines, and ICs against inductive switching transients.
Technical Context
This TVS diode uses junction passivation optimized PAR® design to achieve robust surge handling with minimal capacitance and leakage. Its bidirectional structure enables symmetric clamping across both polarities without external polarity management, and it complies with ANSI/IEEE C62.35 for transient suppression standards.
The device is rated for 1500 W peak pulse power using a 10/1000 µs waveform and supports derated operation up to +185 °C junction temperature. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow compatibility with 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.4 V - maximum continuous reverse working voltage before significant leakage begins |
| VBR (min/max) | 10.5 V / 11.6 V at 1 mA - ensures reliable triggering above system operating voltage |
| VC @ IPPM | 15.6 V at 96.2 A - limits voltage seen by protected downstream circuitry during surge |
| PPPM | 1500 W - handles high-energy transients common in automotive load-dump and inductive switch-off events |
| TJ max | +185 °C - supports under-hood automotive placement and extended thermal margin in industrial enclosures |
| Leakage ID | <5 µA at VWM - avoids parasitic loading on low-power sensor or communication lines |
| Package | SMPC (TO-277A) - surface-mount, low-profile (1.1 mm height), halogen-free, RoHS-compliant |
Pinout & Package
TPC11CAHM3/I is housed in the SMPC (TO-277A) package: a 2-terminal, bidirectional SMD device with no polarity marking. The package conforms to JEDEC TO-277A mechanical dimensions and features matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity assignment |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; symmetrical conduction path enables dual-direction clamping |
Key Features

| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak without moisture sensitivity concerns |
| 1.1 mm typical height | Reduces board clearance issues in stacked or shielded modules and enables compact layout near protected ICs |
| Low leakage <5 µA | Maintains signal integrity on high-impedance analog or digital sensor inputs without DC loading |
Applications
| Automotive Sensor Protection | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and position sensor signal lines from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC input pins to shunt surge energy before it reaches sensitive analog front-ends. Use Value: Prevents latch-up or permanent damage to 3.3 V or 5 V sensor interfaces while maintaining <5 µA leakage to avoid offset errors. | Use Scenario: Safeguarding gate drivers and microcontroller GPIOs from flyback spikes generated by relay or solenoid switching in PLC I/O modules. IC Role / Device Role / Timing Role: Fast-response TVS placed across relay coil terminals or between driver output and ground to clamp inductive kickback. Use Value: Limits transient voltage to ≤15.6 V, ensuring gate oxide integrity and logic-level compatibility for 12 V–24 V control circuits. |
| Consumer Power Adapter Outputs | Telecom Line Interface Protection |
Use Scenario: Suppressing surges on secondary-side 5 V/12 V outputs of AC-DC adapters exposed to mains-borne transients or hot-plug events. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between output rail and ground to absorb repetitive 1500 W pulses without degradation. Use Value: Extends adapter lifespan and prevents downstream USB port or charging circuit failure during surge events per IEC 61000-4-5. | Use Scenario: Shielding Ethernet PHY or RS-485 transceivers from lightning-induced surges on outdoor or long-cable telecom links. IC Role / Device Role / Timing Role: Primary-level TVS mounted at connector entry point to divert >96 A surge current before reaching isolation barrier or line driver. Use Value: Maintains signal integrity with low capacitance and clamps to 15.6 V, compatible with 3.3 V or 5 V transceiver absolute maximum ratings. |
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 | Unidirectional; 10 V VWM; 1500 W PPPM; DO-214AC package (higher profile, 2.3 mm) | Requires polarity-aware layout; not suitable for AC or bidirectional signal lines without external diode pairing | Select when unidirectional clamping suffices and board height allows larger package |
| TPC12CAHM3/I | Higher VWM (10.2 V), VBR (11.4–12.6 V), and VC (16.7 V); same package and AEC-Q101 qualification | Better suited for 12 V nominal systems where tighter VWM/VBR margin is needed versus 9.4 V standoff | Choose for 12 V automotive subsystems requiring higher threshold before clamping activation |
Compared with SMAJ10A and TPC12CAHM3/I, the TPC11CAHM3/I offers the lowest VWM (9.4 V) in the family, enabling earlier clamping in 5 V–9 V systems while retaining full AEC-Q101 compliance and ultra-low profile-critical for modern sensor modules and compact power supplies.

FAQ
What is the maximum clamping voltage of the TPC11CAHM3/I?
The TPC11CAHM3/I has a maximum clamping voltage (VC) of 15.6 V when subjected to its peak pulse current (IPPM) of 96.2 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage during surge events. The TPC11CAHM3/I maintains this clamping performance across its full operating temperature range.
Is the TPC11CAHM3/I suitable for automotive applications?
Yes, the TPC11CAHM3/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for automotive under-hood and body electronics. Its halogen-free, RoHS-compliant construction and MSL Level 1 reflow capability further support automotive manufacturing requirements. The TPC11CAHM3/I is explicitly designated for automotive use via the HM3 suffix in its ordering code.
What does the "HM3" suffix indicate in TPC11CAHM3/I?
The "HM3" suffix in TPC11CAHM3/I denotes Vishay's automotive-qualified variant: halogen-free, RoHS-compliant, AEC-Q101 qualified, and tested to JESD201 Class 2 for tin whisker resistance. It also specifies packaging in 13-inch tape-and-reel (I-code) with 6500 units per reel. The HM3 suffix distinguishes it from commercial variants and confirms compliance with automotive reliability standards.
Does the TPC11CAHM3/I require polarity-aware PCB layout?
No, the TPC11CAHM3/I is a bidirectional TVS diode with no polarity marking on the SMPC (TO-277A) package. Both terminals are functionally identical, allowing symmetric placement across any two-node interface-such as power-to-ground or differential signal pairs-without orientation constraints. This simplifies layout and eliminates risk of incorrect installation during automated assembly.
What is the leakage current specification for TPC11CAHM3/I at its standoff voltage?
The TPC11CAHM3/I exhibits a maximum reverse leakage current (ID) of 5.0 µA at its standoff voltage (VWM) of 9.4 V and ambient temperature of 25 °C. This low leakage preserves signal integrity on high-impedance nodes like sensor outputs or analog monitoring lines and avoids unintended bias shifts in precision circuits powered by the protected rail.
