At that point it clamps the surge to 134V maximum while shunting 4.5A of peak pulse current for the standard 10/1000µs waveform. In a 75V system — say an industrial 48V-to-75V DC bus or a telecom line card — this part sits across the rail and ground, absorbing the surge before it reaches the downstream DC-DC converter or transceiver. Microchip lists the SMBJ75E3/TR13 as Active, so it remains a standard catalog item with no announced end-of-life. The DO-214AA (SMB) package is widely used and second-sourced across the TVS industry, making this a low-risk BOM line for multi-year production runs. Sourcing is confirmed per RFQ; lead time and current pricing are available at quote time. ## Temperature range and mounting note Surface-mount assembly on DO-214AA uses standard reflow profiles; the copper pad area under the cathode tab sets the thermal resistance for pulse derating at elevated ambient temperatures.","metaTitle":"SMBJ75E3/TR13 TVS Diode – 75V, 600W, DO-214AA","metaDescription":"SMBJ75E3/TR13 Zener TVS from Microchip. 75V reverse standoff, 134V clamping, 600W peak pulse power.

The 'A' suffix on SMBJ75A typically denotes a different manufacturer's part marking or a non-RoHS variant.
