Product details
Overview
1N5233B_S00Z from ON Semiconductor is a 6.0 V ±5% tolerance, 500 mW glass-encapsulated Zener diode in DO-35 package, designed for precision voltage regulation and reference applications in low-power analog circuits, power supply feedback loops, and overvoltage protection. It delivers 7.0 Ω dynamic impedance at 20 mA test current and exhibits a temperature coefficient of +0.038 %/°C.
For engineers reviewing the 1N5233B_S00Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.0 V nominal Zener voltage, 500 mW power rating, DO-35 axial glass package, 7.0 Ω Zener impedance, and +0.038 %/°C temperature coefficient - all critical for stable low-current voltage reference design.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse-breakdown characteristics. Its junction is hermetically sealed in a DO-35 glass package, enabling stable operation across -65°C to +200°C junction temperature range and supporting reliable thermal equilibrium during voltage reference use.
It is characterized at 20 mA Zener test current (IZ), with specified Zener voltage (VZ) of 5.7 V min / 6.0 V typ / 6.3 V max, dynamic impedance (ZZ) of 7.0 Ω max, and knee impedance (ZZK) of 1,600 Ω max at IZK = 0.25 mA - confirming suitability for low-noise, low-drift reference circuits where tight regulation and predictable knee behavior are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.7 V min / 6.0 V typ / 6.3 V max @ IZ = 20 mA - defines precise regulation point for feedback and reference circuits. |
| Power Dissipation (PD) | 500 mW @ TA = 25°C - sets maximum continuous power handling in standard ambient conditions. |
| Zener Impedance (ZZ) | 7.0 Ω max @ IZ = 20 mA - ensures low AC impedance for stable regulation under small-signal load variations. |
| Temperature Coefficient (TC) | +0.038 %/°C - indicates positive drift with temperature, enabling predictable compensation in reference designs. |
| Reverse Leakage (IR) | 5.0 μA max @ VR = 3.0 V - confirms low off-state current, minimizing error in high-impedance bias networks. |
| Package | DO-35 glass axial - provides hermetic sealing, stable long-term parameter retention, and compatibility with through-hole assembly. |
Pinout & Package
The 1N5233B_S00Z is a two-terminal axial-leaded device in the DO-35 glass package. The cathode is marked by a color band on the glass body. No internal circuitry or polarity-sensitive terminals beyond anode and cathode exist.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5233B (no suffix) | Same electrical specs and DO-35 package; S00Z denotes specific traceability/lot marking per ON Semi internal coding. | No functional difference; S00Z variant includes enhanced lot-level traceability for automotive/industrial BOM compliance. | Select 1N5233B_S00Z when full material traceability and PPAP documentation are required. |
| BZX55C6V2 | 6.2 V nominal VZ (vs. 6.0 V), ±5% tolerance, same DO-35 package, 10 Ω ZZ - slightly higher voltage and impedance. | Not interchangeable without circuit recalibration; requires resistor divider adjustment to maintain same reference point. | Choose BZX55C6V2 only if 6.2 V is acceptable and legacy stock availability outweighs redesign effort. |
Compared with 1N5233B_S00Z, the base 1N5233B offers identical performance but lacks S00Z's enhanced traceability, while BZX55C6V2 shifts the regulation point by +0.2 V and increases impedance - requiring layout and calibration changes for drop-in replacement.

FAQ
What is the nominal Zener voltage of the 1N5233B_S00Z?
The 1N5233B_S00Z has a nominal Zener voltage of 6.0 V, with a guaranteed range of 5.7 V minimum to 6.3 V maximum at 20 mA test current. This value is measured under thermal equilibrium at lead temperature of 30°C ± 1°C, per ON Semiconductor's characterization methodology. The 1N5233B_S00Z maintains this specification across its qualified operating temperature range.
Does the 1N5233B_S00Z have a specified Zener impedance?
Yes, the 1N5233B_S00Z has a maximum Zener impedance (ZZ) of 7.0 Ω at 20 mA Zener test current. This low dynamic impedance ensures minimal voltage variation under small-signal load changes, making the 1N5233B_S00Z suitable for precision shunt regulation. The impedance is validated per ON Semiconductor's Rev. 3 datasheet under defined thermal test conditions.
What is the temperature coefficient of the 1N5233B_S00Z?
The 1N5233B_S00Z has a temperature coefficient of +0.038 %/°C, indicating a positive drift in Zener voltage with rising temperature. This value is typical and applies across the rated operating junction temperature range. Designers use this coefficient to model thermal drift in reference circuits where the 1N5233B_S00Z serves as a primary voltage node.
Is the 1N5233B_S00Z compatible with lead-free soldering processes?
Yes, the 1N5233B_S00Z's DO-35 glass package supports lead-free reflow and hand-soldering per J-STD-020 guidelines. Its lead temperature rating is +230°C for 10 seconds at 1/16 inch from case, exceeding standard Pb-free process requirements. The 1N5233B_S00Z also complies with ON Semiconductor's RoHS and REACH declarations for industrial assembly.
How does the "S00Z" suffix affect the 1N5233B_S00Z's functionality?
The "S00Z" suffix on 1N5233B_S00Z denotes an ON Semiconductor internal traceability code - not a functional variant. Electrically and mechanically, the 1N5233B_S00Z matches the base 1N5233B part in all specifications, including VZ, ZZ, PD, and package. The S00Z marking enables lot-level tracking for quality and compliance reporting, especially in automotive and industrial BOMs.
