Product details
Overview
SMPC54ANHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for high-energy surge protection with 54 V standoff voltage (VWM), 60–66.3 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 μs. It delivers clamping voltage of 87.1 V at 17.2 A IPPM and operates across -55 °C to +150 °C junction temperature, targeting automotive-grade ESD and load-dump protection on power rails and signal lines.
For engineers reviewing the SMPC54ANHM3/H datasheet, SMPC54ANHM3/H pinout, SMPC54ANHM3/H application, or SMPC54ANHM3/H equivalent, this device is selected for AEC-Q101-compliant transient suppression where low-profile mounting (1.1 mm height), fast response time, and low incremental surge resistance are critical in space-constrained automotive and industrial PCBs.
Technical Context
This TVS diode uses a silicon avalanche structure optimized for unidirectional clamping, with cathode-band polarity marking and dual-anode/dual-cathode terminal configuration per SMPC (TO-277A) mechanical layout. Its thermal design supports junction-to-mount thermal resistance as low as 2.5 °C/W when heatsinked, enabling robust surge handling under repetitive transients.
The device meets J-STD-020 MSL Level 1 (260 °C peak reflow), passes JESD201 Class 2 whisker testing, and is halogen-free, RoHS-compliant, and AEC-Q101 qualified - confirming suitability for automotive power electronics requiring long-term reliability under thermal cycling and vibration stress.
Key Specifications

|---|---|
Use Scenario: Protecting 48 V battery-fed ECUs from load dump transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp overvoltage spikes before they reach DC-DC converters or microcontrollers. Use Value: With 87.1 V clamping at 17.2 A and 1500 W PPPM, SMPC54ANHM3/H holds downstream voltage below 90 V during 100 ms surges, preserving 100 V-rated input stages. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: Low-capacitance TVS connected inline on differential signal pairs to suppress sub-100 ns ESD events without distorting signal integrity. Use Value: 1.1 mm profile allows placement directly at connector entry points; unidirectional behavior avoids forward-bias interference with active sensor biasing circuits. |
| Telecom DC Power Input Protection | Consumer Device USB Power Path Guarding |
Use Scenario: Safeguarding PoE-powered equipment inputs against lightning-induced surges on 48 V DC feeds. IC Role / Device Role / Timing Role: Primary-level TVS mounted upstream of DC-DC isolation stage to absorb energy before it reaches galvanically isolated circuitry. Use Value: 1500 W PPPM and 2.5 °C/W RθJM enable sustained operation after multiple 10/1000 μs surges without thermal runaway, meeting IEC 61000-4-5 Level 4 requirements. |
Use Scenario: Preventing damage to USB-C PD controllers during hot-plug events or cable-induced transients in portable audio/video gear. IC Role / Device Role / Timing Role: Standoff-rated TVS on VBUS line to block >54 V spikes while remaining transparent during normal 5–20 V PD negotiation. Use Value: Tight 60–66.3 V VBR window ensures no false triggering during 20 V PD mode, while 87.1 V VC limits controller exposure during 1 kV ESD contact discharge. |

FAQ
What is the polarity configuration of SMPC54ANHM3/H?
SMPC54ANHM3/H is a unidirectional TVS diode with cathode-band marking indicating the cathode terminal. Internally, it features dual-anode and single-cathode terminals per the SMPC (TO-277A) mechanical layout - meaning Anode 1 and Anode 2 are internally tied, and Cathode is the sole output node for clamping action toward ground.
Does SMPC54ANHM3/H meet automotive qualification standards?
Yes, SMPC54ANHM3/H is AEC-Q101 qualified, as confirmed by Vishay's documentation for the SMPCxxAN-HM3 family. This qualification covers temperature cycling, high-temperature operating life, ESD, and mechanical shock testing required for automotive powertrain and body electronics applications.
What is the maximum clamping voltage for SMPC54ANHM3/H at rated surge current?
The maximum clamping voltage (VC) for SMPC54ANHM3/H is 87.1 V at 17.2 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can SMPC54ANHM3/H be used in bidirectional configurations?
No, SMPC54ANHM3/H is strictly unidirectional. Its internal structure and electrical characteristics - including specified VBR only in the reverse direction and absence of forward VBR data - confirm it is not rated or characterized for bidirectional operation. For bidirectional protection, a separate symmetric TVS or back-to-back configuration is required.
What is the thermal resistance from junction to mount for SMPC54ANHM3/H?
The typical junction-to-mount thermal resistance (RθJM) for SMPC54ANHM3/H is 2.5 °C/W, measured using JEDEC® 51-14 Transient Dual Interface Method. This low value supports efficient heat transfer to a copper pour or heatsink, enabling sustained surge handling in thermally demanding environments.
