Equivalent & Substitute Parts for BZX84B33VLFHT116 Zener Diode

Part Overview

The BZX84B33VLFHT116 is a 33 V, 250 mW Zener diode from Rohm Semiconductor in the Diodes, Zener category. It is supplied in Cut Tape (CT) and Digi-Reel® packaging, with a surface mount design compatible with the SSD3 (SOT-23) package. This device provides voltage regulation with ±2.12% tolerance, a maximum impedance of 80 Ohms, and a reverse leakage current of 100 nA at 23 V. It is AEC-Q101 qualified for automotive applications, RoHS3 compliant, and REACH unaffected.

In engineering applications, alternative models may be required due to supply chain variability, inventory changes, or procurement standardization. Selecting parametric equivalents ensures form, fit, and function are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based on exact matching of the following critical parameters: Zener voltage (33 V), tolerance (±2.12%), maximum power dissipation (250 mW), maximum impedance (80 Ohms), reverse leakage (100 nA @ 23 V), automotive qualification (AEC-Q101), package compatibility (TO-236-3, SC-59, SOT-23-3), surface mount configuration, RoHS3 compliance, REACH status, and MSL. Only parts that correspond to these parameters are classified as parametric equivalents.
