Nexperia USA Inc. BZV90-C8V2,115

Overview

BZV90-C8V2,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at nominal 8.2 V with ±5% tolerance, 5 mA test current, 6.2 Ω typical differential resistance, and −40 °C to +150 °C junction temperature range; used in power supply feedback loops and analog sensor biasing circuits.

For engineers reviewing the BZV90-C8V2,115 datasheet, BZV90-C8V2,115 pinout, BZV90-C8V2,115 application, or BZV90-C8V2,115 equivalent, key selection criteria include Zener voltage accuracy at 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), and SOT223 thermal pad layout compatibility with FR4 PCB copper area ≥2 cm².

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its E24-standard 8.2 V nominal point. Its differential resistance of 6.2 Ω (typical) ensures stable regulation under varying load currents, while its negative temperature coefficient of +3.2 mV/K (at I_Z = 5 mA) enables predictable drift compensation in temperature-sensitive references.

The device supports pulsed operation up to 40 W for 100 μs durations at T_j = 25 °C, and maintains ≤0.7 μA reverse leakage at VR = 6.56 V (80% of V_Z). Its 1500 mW continuous power dissipation rating requires thermal management via the exposed collector pad in the SOT223 package.

FAQ

What is the maximum continuous reverse current this Zener can handle at 8.2 V?

The BZV90-C8V2,115 supports a continuous Zener test current of 5 mA per datasheet specifications. At this current, it maintains nominal 8.2 V regulation with 6.2 Ω differential resistance. Exceeding 5 mA continuously risks exceeding the 1500 mW total power limit unless PCB thermal design reduces junction temperature rise below 150 °C.

Can this diode replace a 1N4733A in an existing design?

Yes, the BZV90-C8V2,115 is functionally equivalent to the 1N4733A (8.2 V, ±5%) but offers superior thermal performance: 1500 mW P_tot vs. 1000 mW, and SOT223's 83.3 K/W R_{th j-a} vs. DO-41's ~100 K/W. However, the 4-pin SOT223 footprint requires PCB layout revision-Pins 2 and 4 are both cathode, unlike the 2-pin DO-41 leadform.

How does temperature affect its Zener voltage stability?

At I_Z = 5 mA, the BZV90-C8V2,115 exhibits a positive temperature coefficient of +3.2 mV/K, meaning its Zener voltage increases by ~0.27 V over a 85 °C rise (25 °C to 110 °C). This behavior is documented in Figure 5 of the datasheet and must be factored into high-accuracy reference designs using external compensation.

Is the SOT223 package lead-free and RoHS compliant?

Yes, the BZV90-C8V2,115 is manufactured in accordance with Nexperia's standard RoHS-compliant process. The SOT223 package uses lead-free solderable terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), with no exemption required for lead content under EU Directive 2011/65/EU.
