Product details
Overview
TPC16AHM3_A/I from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for clamping voltage transients on power rails and signal lines. It features a standoff voltage of 13.6 V, breakdown voltage range of 15.2–16.8 V at 1 mA, clamping voltage of 22.5 V at 66.7 A, and operates from −65 °C to +185 °C - ideal for automotive power supply protection.
For engineers reviewing the TPC16AHM3_A/I datasheet, TPC16AHM3_A/I pinout, TPC16AHM3_A/I application, or TPC16AHM3_A/I equivalent, key selection criteria include unidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 1.1 mm profile for space-constrained PCBs, and compatibility with automated SMT placement.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and inductive switching transients. Its junction temperature rating of 185 °C supports under-hood automotive environments and high-reliability industrial power supplies.
The device is rated for 1500 W peak pulse power (10/1000 μs waveform), with clamping performance validated at 66.7 A peak pulse current. It meets JESD201 Class 2 whisker testing and is halogen-free, RoHS-compliant, and qualified per AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VBR min/max | 15.2 V / 16.8 V at 1 mA - ensures reliable breakdown initiation within tight tolerance band |
| VC @ IPPM | 22.5 V at 66.7 A - clamping voltage limits downstream IC stress during 10/1000 μs surges |
| PPPM | 1500 W - peak pulse power handling capacity for transient energy absorption |
| TJ max | +185 °C - enables operation in high-temperature engine control units and power converters |
| Package | TO-277A (SMPC) - surface-mount, low-profile (1.1 mm height), AEC-Q101 qualified |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation in circuit |
Pinout & Package
TO-277A (SMPC) package: 3-terminal surface-mount configuration with cathode-anode-cathode layout. Matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability standards; HM3 suffix denotes halogen-free, RoHS-compliant, AEC-Q101 qualified construction.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontrollers and CAN transceivers from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between power rail and ground. Use Value: Limits voltage to ≤22.5 V during 66.7 A surges, preventing latch-up or permanent damage to downstream logic. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Signal-line TVS connected across differential or single-ended output pins. Use Value: Sub-1 ns response time suppresses transients before they propagate into ADC front-ends or op-amps. |

IC Role / Device Role / Timing Role: Front-end TVS on 48 V input bus prior to primary-side controller and transformer. Use Value: 185 °C junction rating allows operation adjacent to hot-running magnetics and MOSFETs without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 24.4 V at 24.4 A | Not AEC-Q101 qualified; limited to commercial/industrial use | Choose for cost-sensitive non-automotive designs where 1500 W surge margin is not required |
| TPC16AHE3_A/I | Same electrical specs but HE3 suffix indicates different tape/reel packaging (7″ vs. 13″); identical TO-277A die and construction | No functional difference; only logistics variation for procurement planning | Select based on preferred reel size and volume delivery requirements |
Compared with SMAJ15A and TPC16AHE3_A/I, the TPC16AHM3_A/I uniquely combines AEC-Q101 qualification, 1500 W surge rating, and 1.1 mm profile in a single TO-277A package - making it optimal for space- and reliability-critical automotive power nodes.

FAQ
What is the clamping voltage of TPC16AHM3_A/I at its rated peak pulse current?
The TPC16AHM3_A/I has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 66.7 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for protected circuits. The TPC16AHM3_A/I maintains this clamping performance across its full operating temperature range up to +185 °C.
Is TPC16AHM3_A/I qualified for automotive applications?
Yes, the TPC16AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is rated for junction temperatures up to +185 °C and meets JESD201 Class 2 whisker testing - confirming suitability for under-hood and powertrain applications. The TPC16AHM3_A/I is explicitly listed in Vishay's automotive-qualified product documentation.
What does the "HM3" suffix mean in TPC16AHM3_A/I?
The "HM3" suffix in TPC16AHM3_A/I identifies the device as halogen-free, RoHS-compliant, and AEC-Q101 qualified, per Vishay's material categorization standard (Doc. 99912). It also specifies matte tin-plated terminals meeting J-STD-002 and JESD22-B102, and JESD201 Class 2 whisker resistance. The TPC16AHM3_A/I shares all electrical and thermal characteristics with non-HM3 variants - only material and qualification attributes differ.
Can TPC16AHM3_A/I be used in bidirectional configurations?
No, the TPC16AHM3_A/I is strictly unidirectional and must be oriented with its anode connected to ground or the lower-potential node. Bidirectional protection requires either two TPC16AHM3_A/I devices in series opposition or a dedicated bidirectional TVS such as the SMBJ15CA. Using the TPC16AHM3_A/I in reverse polarity will result in forward conduction and failure to clamp negative transients.
What is the moisture sensitivity level (MSL) rating for TPC16AHM3_A/I?
The TPC16AHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be stored and processed without dry packing or baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during assembly. The TPC16AHM3_A/I achieves this via robust molding compound and hermetic leadframe sealing inherent to the TO-277A (SMPC) package.
