Product details
Overview
BZV55-B8V2,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 8.2 V nominal regulation at 5 mA with ±2 % tolerance, 40 Ω typical differential resistance, and 700 nA reverse leakage at 5 V. It delivers stable reference voltage in power supply feedback loops, overvoltage protection circuits, and precision biasing networks for analog front-ends.
For engineers reviewing the BZV55-B8V2,135 datasheet, BZV55-B8V2,135 pinout, BZV55-B8V2,135 application, or BZV55-B8V2,135 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and validated alternative parts for voltage reference design continuity.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 8.2 V reference across load and line variations, with temperature coefficient of +3.2 mV/K at 5 mA - enabling predictable drift compensation in mid-voltage references. Its low 40 Ω differential resistance ensures minimal output impedance under dynamic current changes.
Designed for transient suppression and DC regulation, it withstands non-repetitive 40 W peak reverse power (100 µs square wave) and dissipates up to 500 mW total power on a ceramic substrate. Reverse leakage remains tightly controlled at 700 nA at VR = 5 V, supporting low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Tolerance | ±2 % - ensures tight binning for high-accuracy voltage setting without trimming |
| Differential Resistance | 40 Ω typ. at IZ = 5 mA - limits output voltage variation under ±1 mA load shifts |
| Reverse Leakage Current | 700 nA at VR = 5 V - preserves low quiescent current in battery-backed or energy-harvesting systems |
| Non-repetitive Peak Power | 40 W (100 µs pulse) - supports transient overvoltage clamping without failure |
| Total Power Dissipation | 500 mW at Tj ≤ 50 °C on ceramic substrate - sets thermal derating boundary for PCB layout |
| Thermal Resistance j-a | 380 K/W in free air - informs minimum copper area needed for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C8V2 | ±5 % tolerance, higher 100 Ω rdif, 1 µA IR at 5 V | Acceptable where cost > precision; less stable under load variation | Select when ±5 % regulation tolerance suffices and leakage sensitivity is low |
| MMSZ5236B | SOD-123 package, ±5 %, 30 Ω rdif, 1 µA IR at 5 V, 500 mW rating | Compatible footprint but different thermal profile; requires revalidation of solder joint reliability | Choose for higher-volume assembly where SOD-123 is standard and tighter rdif is prioritized over leakage |
Compared with BZV55-B8V2,135, BZX55C8V2 trades precision for cost and MMSZ5236B offers lower dynamic impedance but looser tolerance and higher leakage - making the BZV55-B8V2,135 optimal for applications demanding both tight voltage control and ultra-low standby current.

FAQ
What is the maximum continuous reverse current for BZV55-B8V2,135?
The device has no specified maximum continuous reverse current; instead, its safe operating limit is defined by total power dissipation (500 mW at Tj ≤ 50 °C on ceramic substrate). At 8.2 V, this corresponds to ~61 mA average Zener current - exceeding which risks thermal runaway without adequate heatsinking.
Does BZV55-B8V2,135 support reflow soldering per JEDEC J-STD-020?
Yes - the SOD80C package is qualified for standard lead-free reflow profiles (peak 260 °C, 30 s max), with recommended footprint dimensions published in Figure 7 of the datasheet (2.30 mm × 4.30 mm solder land pattern).
How does temperature affect the 8.2 V regulation voltage?
At 5 mA test current, the temperature coefficient is +3.2 mV/K - meaning the Zener voltage increases by ~3.2 mV per Kelvin rise in junction temperature. This positive drift is typical for Zeners in the 6–10 V range and must be accounted for in wide-temperature-range applications.
Can BZV55-B8V2,135 replace BZV55-C8V2 in existing designs?
No - BZV55-C8V2 has ±5 % tolerance (7.6–8.8 V range) versus BZV55-B8V2,135's ±2 % (8.04–8.36 V), resulting in up to 160 mV higher worst-case voltage. Substitution may cause overregulation or false triggering in precision circuits unless system margins accommodate the wider spread.
