Product details

Overview

1N5234B_S00Z from ON Semiconductor is a 6.2 V ±5% Zener diode in DO-35 glass package, rated for 500 mW power dissipation at 25°C, with 7 Ω dynamic impedance at 20 mA test current and 5 μA maximum reverse leakage at 4.0 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog circuits.

For engineers reviewing the 1N5234B_S00Z datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance, temperature coefficient (+0.045 %/°C), junction temperature range (–65 to +200°C), and DO-35 mechanical compatibility with through-hole PCB layouts.

Technical Context

This device operates in reverse breakdown mode with stable regulation across its specified current range (0.25–20 mA). Its 7 Ω Zener impedance ensures minimal output voltage variation under load changes, while the +0.045 %/°C temperature coefficient enables predictable drift compensation in reference designs.

The DO-35 hermetically sealed glass package provides reliable thermal conduction and long-term stability in industrial environments. With a maximum forward voltage of 1.2 V at 200 mA, it supports bidirectional protection configurations when paired with another diode.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5234B (no suffix)	Same electrical specs; differs only in top-marking format per ON Semi's post-Fairchild branding update	No functional difference; identical DO-35 package and performance	Select when sourcing standard marking variant without S00Z traceability code
BZX55C6V2	Same 6.2 V ±5%, but higher Z_Z (10 Ω) and wider tempco (±0.05 %/°C); DO-35 compatible	Suitable for less demanding references where tighter impedance control is not required	Choose for cost-sensitive designs accepting slightly reduced regulation accuracy

Compared with 1N5234B_S00Z, the 1N5234B offers identical performance with simplified marking, while BZX55C6V2 trades 3 Ω higher impedance and looser tempco for broader distributor availability and lower unit cost in non-critical applications.

FAQ

What is the Zener voltage tolerance of the 1N5234B_S00Z?

The 1N5234B_S00Z has a Zener voltage tolerance of ±5% around its nominal 6.2 V rating, meaning the actual measured V_Z falls between 5.89 V and 6.51 V when tested at 20 mA and 25°C. This tolerance is guaranteed per ON Semiconductor's 1N5221B–1N5263B datasheet Rev. 3, and applies directly to the 1N5234B_S00Z variant.

Does the 1N5234B_S00Z have a specified forward voltage?

Yes, the 1N5234B_S00Z has a maximum forward voltage (V_F) of 1.2 V at 200 mA forward current, as stated in the Absolute Maximum Ratings section of the ON Semiconductor datasheet. This value is relevant for bidirectional protection configurations or when used in series with other components in forward conduction mode.

What is the Zener impedance (Z_Z) of the 1N5234B_S00Z and why does it matter?

The 1N5234B_S00Z exhibits a Zener impedance (Z_Z) of 7 Ω at 20 mA test current. This low impedance ensures minimal change in output voltage under varying load conditions - critical for maintaining accuracy in reference circuits where load current may fluctuate by ±5 mA.

Can the 1N5234B_S00Z be used in surface-mount designs?

No, the 1N5234B_S00Z uses a DO-35 axial glass package intended for through-hole mounting only. It lacks solder pads or terminations compatible with reflow or wave soldering processes. For SMT equivalents, consider ON Semiconductor's NZ9F6V2 or similar SOD-123 packaged Zeners.

What is the maximum operating junction temperature for the 1N5234B_S00Z?

The 1N5234B_S00Z has a specified operating junction temperature range of –65°C to +200°C, as defined in the Absolute Maximum Ratings table. This wide range allows reliable operation in harsh environments such as automotive engine compartments or industrial motor controls where ambient temperatures exceed 125°C.
