Product details
Overview
1N5232B_S00Z from ON Semiconductor is a 5.6 V, ±5% tolerance, 500 mW silicon Zener diode in DO-35 glass package, designed for precision voltage regulation and reference applications at 20 mA test current with 11 Ω dynamic impedance and +0.038 %/°C temperature coefficient.
For engineers reviewing the 1N5232B_S00Z datasheet, pinout, applications, or equivalent options, this device serves as a low-power, stable voltage reference in analog signal conditioning, power supply feedback loops, and overvoltage protection circuits where tight voltage tolerance and predictable thermal drift are required.
Technical Context
The 1N5232B_S00Z operates as a reverse-biased Zener diode with a nominal breakdown voltage of 5.6 V at IZ = 20 mA, exhibiting a typical dynamic impedance (ZZ) of 11 Ω and a low leakage current (IR ≤ 5.0 μA at VR = 4.0 V). Its temperature coefficient of +0.038 %/°C indicates slight positive drift over temperature, enabling predictable behavior in ambient-stable designs.
It is rated for 500 mW power dissipation at TA = 25°C with 4.0 mW/°C derating above 50°C, and supports junction temperatures from –65°C to +200°C - suitable for industrial and automotive under-hood environments where thermal robustness is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V ±5% at IZ = 20 mA - defines precise clamping/reference level in regulation circuits |

| Dynamic Impedance (ZZ) | 11 Ω at IZ = 20 mA - determines output voltage stability under load variation |
| Temperature Coefficient (TC) | +0.038 %/°C - quantifies voltage drift per degree Celsius for thermal design margining |
| Reverse Leakage (IR) | ≤5.0 μA at VR = 4.0 V - ensures minimal quiescent current in standby or high-impedance bias networks |

FAQ
What is the Zener voltage tolerance of the 1N5232B_S00Z?
The 1N5232B_S00Z has a Zener voltage tolerance of ±5% at IZ = 20 mA, meaning its breakdown voltage falls between 5.32 V and 5.88 V under specified test conditions. This tolerance is guaranteed per ON Semiconductor's 1N5221B–1N5263B datasheet Rev. 3, and applies directly to the 1N5232B_S00Z as a member of that family.
Does the 1N5232B_S00Z have a specified forward voltage?
Yes - the 1N5232B_S00Z specifies a maximum forward voltage (VF) of 1.2 V at IF = 200 mA, per the "Electrical Characteristics" table on page 2 of the ON Semiconductor 1N5221B–1N5263B datasheet. This value is relevant for forward-conduction scenarios such as polarity protection or ESD diode stacking.
What is the maximum power dissipation for the 1N5232B_S00Z at 75°C ambient?
At 75°C ambient, the 1N5232B_S00Z must be derated from its 500 mW rating at 25°C by 4.0 mW/°C for each degree above 50°C. From 50°C to 75°C is a 25°C rise, so derating is 100 mW. Thus, maximum allowable power is 400 mW - confirmed in the Absolute Maximum Ratings table of the official ON Semiconductor datasheet.
Is the 1N5232B_S00Z available in tape-and-reel packaging?
Yes - the 1N5232B_S00Z is offered in tape-and-reel packaging per ON Semiconductor's ordering information, with standard reels containing 2,000 units. Tape-and-reel format supports automated SMT placement when used with appropriate axial-to-SMT adapters, though the DO-35 package itself is through-hole optimized.
What does the "_S00Z" suffix indicate in the 1N5232B_S00Z part number?
The "_S00Z" suffix denotes a Fairchild-originated marking variant later integrated into ON Semiconductor's system; it identifies the same 1N5232B device in DO-35 package with standard electrical specs. Per ON Semiconductor's integration notice, underscores were replaced with dashes for system compatibility, but _S00Z remains a valid orderable identifier for this exact Zener diode.
