Product details
Overview
TPC30CAHM3/H from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial electronics protection. It features a standoff voltage of 25.6 V, breakdown voltage range of 28.5–31.5 V at 1 mA, clamping voltage of 41.4 V at 36.2 A, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC30CAHM3/H datasheet, TPC30CAHM3/H pinout, TPC30CAHM3/H application, or TPC30CAHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, MSL Level 1 rating, low-profile 1.1 mm height, bidirectional surge suppression capability, and compatibility with automated SMT placement on automotive sensor signal lines and power rails.
Technical Context
The TPC30CAHM3/H implements a junction-passivated PAR® design optimized for fast response to transients induced by inductive load switching or ESD events. Its bidirectional structure enables symmetrical clamping without polarity concerns, and it maintains stable performance across -65 °C to +185 °C operating junction temperature.
Rated for 1500 W peak pulse power (10/1000 μs waveform), the device delivers 36.2 A peak pulse current with 41.4 V clamping voltage. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow requirements (260 °C peak).

Applications
| Automotive Sensor Protection | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN signal lines and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point to clamp surges before reaching MCU or analog front-end. Use Value: Maintains signal integrity with ≤1 μA leakage at 25.6 V and clamps 36.2 A transients to 41.4 V, preventing latch-up in 3.3 V/5 V interface ICs. | Use Scenario: Safeguarding gate driver inputs and feedback sensing nodes in variable-frequency drives exposed to inductive kickback from 3-phase motors. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing repetitive 1500 W surges without degradation, mounted adjacent to IGBT/MOSFET gate drivers. Use Value: Withstands junction temperatures up to +185 °C and passes JESD201 Class 2 whisker test, ensuring reliability in thermally demanding motor control enclosures. |
| Telecom Power Input Stage | Consumer USB-C Power Delivery Protection |
Use Scenario: Front-end surge suppression on 24–48 V DC power inputs of base station remote radio units and PoE-powered equipment. IC Role / Device Role / Timing Role: Primary clamping device in multi-stage protection circuit, coordinating with upstream GDT and downstream polymer PTC. Use Value: Delivers 1500 W peak pulse power handling and 41.4 V clamping to protect 48 V-rated DC-DC controllers from lightning-induced surges per IEC 61000-4-5. | Use Scenario: Overvoltage protection on VBUS lines of USB-C receptacles in portable docking stations and monitors subject to hot-plug transients. IC Role / Device Role / Timing Role: Fast-response bidirectional TVS placed between connector and USB PD controller to limit VBUS excursions during cable insertion/removal. Use Value: Low 1.1 mm profile allows placement in tight connector keep-out zones; AEC-Q101 qualification ensures robustness against repeated electrostatic discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | Unidirectional; 33 V VWM; 36.7 V VBR min; 53.3 V VC @ 28.1 A; SMA package | Requires external polarity awareness; higher clamping voltage reduces margin for 3.3 V logic protection | Select when unidirectional operation suffices and board layout accommodates larger SMA footprint |
| TPC33CAHM3/H | Bidirectional; 28.2 V VWM; 31.4–34.7 V VBR; 45.7 V VC @ 32.8 A; same SMPC package | Higher clamping voltage but wider VBR tolerance; suitable for 24 V systems requiring greater margin | Choose for upgraded 24 V rail protection where 45.7 V clamping remains within downstream IC absolute maximum ratings |
Compared with SMAJ33A-E3/57T and TPC33CAHM3/H, the TPC30CAHM3/H offers tighter VBR tolerance (28.5–31.5 V), lower clamping (41.4 V), and optimal fit for 24 V automotive sensor lines where precise voltage limiting and minimal board height are critical.

FAQ
What is the maximum clamping voltage of TPC30CAHM3/H under standard test conditions?
The TPC30CAHM3/H has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 36.2 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during surge events. The TPC30CAHM3/H maintains this clamping performance across its full operating temperature range.
Is TPC30CAHM3/H qualified for automotive applications?
Yes, TPC30CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating compliance with automotive reliability standards, including JESD201 Class 2 whisker resistance and MSL Level 1 reflow capability. Its +185 °C maximum junction temperature rating and halogen-free, RoHS-compliant construction make it suitable for under-hood and body-control module deployments.
What does the "HM3" suffix indicate in TPC30CAHM3/H?
The "HM3" suffix in TPC30CAHM3/H denotes Vishay's automotive-grade variant: halogen-free, RoHS-compliant, AEC-Q101 qualified, and tested to JESD201 Class 2 for tin whisker resistance. It also specifies packaging in 7-inch plastic tape-and-reel format with 1500 units per reel, optimized for high-speed SMT placement.
Can TPC30CAHM3/H be used in bidirectional signal line protection?
Yes, TPC30CAHM3/H is inherently bidirectional and requires no polarity orientation during placement. Its symmetrical VBR characteristics (28.5–31.5 V in both directions) enable effective protection of AC-coupled or differential signal lines such as CAN, LIN, or RS-485, where voltage transients may occur with either polarity relative to ground.
What is the standoff voltage rating of TPC30CAHM3/H?
The standoff voltage (VWM) of TPC30CAHM3/H is 25.6 V - the maximum DC or continuous reverse working voltage that can be applied without exceeding 1 μA leakage current. This rating ensures compatibility with nominal 24 V automotive and industrial power rails while maintaining sufficient margin below the 28.5 V minimum breakdown voltage.
