Product details
Overview
BZT52-C8V2J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 8.2 V nominal regulation at 5 mA, with 80 Ω max differential resistance and 0.7 μA reverse current at 6.2 V, used for precision voltage reference and low-power rail stabilization in consumer power management circuits.
For engineers reviewing the BZT52-C8V2J datasheet, BZT52-C8V2J pinout, BZT52-C8V2J application, or BZT52-C8V2J equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, thermal resistance data, and direct substitution guidance for surface-mount voltage regulation design.
Technical Context
This Zener operates in reverse breakdown mode with a temperature coefficient of +3.2 to +6.2 mV/K at IZ = 5 mA, enabling stable reference generation across -55 °C to +150 °C ambient. Its low 80 Ω differential resistance ensures minimal output voltage drift under load variation up to 250 mA forward current.
The device uses planar epitaxial construction for tight voltage tolerance control and low leakage, with thermal resistance from junction to solder point at 55 K/W - critical for thermal design on FR4 PCBs with 1 cm² cathode pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 8.2 V at IZ = 5 mA - defines regulated output level for biasing or reference circuits |
| Tolerance | ±5 % - specifies maximum deviation from nominal voltage under standard test conditions |
| Differential Resistance | ≤ 80 Ω - determines output impedance and load regulation sensitivity |
| Reverse Current | ≤ 0.7 μA at VR = 6.2 V - sets minimum leakage impact on high-impedance nodes |
| Total Power Dissipation | 590 mW at Tamb ≤ 25 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| Junction Temperature | 150 °C max - constrains thermal derating curves for sustained operation |
| Thermal Resistance (j–sp) | 55 K/W - quantifies temperature rise per watt at cathode solder point for layout thermal modeling |
Pinout & Package
SOD123 plastic surface-mounted package: 2-terminal, flat lead, cathode-marked with bar; dimensions 3.75 mm × 1.7 mm × 1.3 mm (L × W × H), 1.0 mm lead pitch, 0.7 mm lead width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low differential resistance | 80 Ω max ensures <10 mV output shift per 0.8 mA load change - critical for stable analog references |
| Controlled temperature coefficient | +3.2 to +6.2 mV/K allows predictable drift compensation in temperature-sensitive circuits |
| Small SMD footprint | SOD123 package enables high-density placement on compact PCBs without through-hole routing |
| High surge robustness | 40 W non-repetitive peak reverse power dissipation supports transient overvoltage protection duty cycles |
| Low leakage performance | 0.7 μA IR at 6.2 V minimizes quiescent current draw in battery-powered sensor nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-B8V2 | ±2 % tolerance, 150 Ω max rdif, +0.4 to +3.7 mV/K tempco | Higher precision but higher impedance - better for low-current references, worse for load regulation | Select when absolute voltage accuracy >0.1 V matters more than dynamic response |
| MMBZ5231BS | Same 8.2 V nominal, SOT-23 package, 100 Ω rdif, ±5 %, 350 mW Ptot | Larger footprint and higher thermal resistance - limits power handling on dense layouts | Choose only if SOT-23 compatibility required; avoid when board space or thermal margin is constrained |
Compared with BZT52-C8V2J, BZT52-B8V2 offers tighter voltage control but sacrifices regulation stiffness, while MMBZ5231BS trades package miniaturization for reduced thermal performance and higher dynamic impedance - making BZT52-C8V2J optimal for cost-sensitive, thermally constrained SMD regulation where ±5 % tolerance is acceptable.

FAQ
What is the maximum continuous reverse power dissipation for BZT52-C8V2J at 70 °C ambient?
At 70 °C ambient, BZT52-C8V2J's total power dissipation must be derated linearly from 590 mW at 25 °C using its 55 K/W junction-to-solder-point thermal resistance. This yields a maximum continuous reverse power of approximately 360 mW to maintain junction temperature ≤150 °C, assuming proper 1 cm² cathode copper pad.
Can BZT52-C8V2J replace BZT52-B8V2 in an existing design without layout changes?
Yes - both share identical SOD123 package, pinout, and marking orientation (cathode bar). However, BZT52-C8V2J's wider ±5 % tolerance and lower differential resistance may alter regulation accuracy and load transient response; verify stability under worst-case load and temperature conditions before substitution.
What is the typical reverse recovery time for BZT52-C8V2J during transient clamping?
Zener diodes like BZT52-C8V2J do not specify reverse recovery time because they operate in steady-state reverse breakdown, not switching mode. Their clamping response is limited by junction capacitance (150 pF at 0 V) and package inductance - typically sub-nanosecond for ESD events, confirmed by IEC 61000-4-2 testing.
Is BZT52-C8V2J qualified for automotive applications?
No - per Nexperia's revision history (Rev. 2, October 2025), the C-series BZT52 devices are explicitly designated as non-automotive qualified. For automotive use, select the -Q qualified variants such as BZT52-C8V2J-Q, which undergo extended temperature cycling, AEC-Q200 stress testing, and PPAP documentation.
