Product details
Overview
1N5252B_S00Z from ON Semiconductor is a 5% tolerance, 24 V Zener diode in DO-35 glass package, rated for 500 mW power dissipation at 25°C, with 33 Ω dynamic impedance at 20 mA test current and ±0.088 %/°C temperature coefficient. It provides precise voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the 1N5252B_S00Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal derating behavior, cathode identification, and direct replacement options for legacy Fairchild-designated Zener diodes in industrial and consumer power management designs.
Technical Context
This device operates as a two-terminal voltage reference, conducting in reverse breakdown when cathode-to-anode voltage exceeds its nominal 24 V Zener voltage (VZ) at IZ = 20 mA. Its DO-35 hermetically sealed glass package ensures stable long-term VZ drift and low leakage under ambient storage conditions from −65°C to +200°C.
The 1N5252B_S00Z exhibits a positive temperature coefficient of +0.088 %/°C, indicating VZ increases linearly with junction temperature - a critical factor when designing temperature-compensated references or selecting complementary devices for thermal stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.8 V min / 24 V typ / 25.2 V max at IZ = 20 mA - defines regulated output voltage window under standard test conditions |
| Dynamic Impedance (ZZ) | 33 Ω max at IZ = 20 mA - determines output voltage variation under load current changes |
| Power Dissipation (PD) | 500 mW at TA = 25°C, derates 4.0 mW/°C above 50°C - sets maximum continuous thermal operating envelope |
| Reverse Leakage (IR) | 0.1 μA max at VR = 19.2 V - ensures minimal quiescent current in standby or high-impedance bias networks |
| Temperature Coefficient (TC) | +0.088 %/°C - quantifies VZ drift per degree Celsius rise, used for thermal error budgeting |
| Forward Voltage (VF) | 1.2 V max at IF = 200 mA - specifies forward conduction drop when used as clamp or rectifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5252BRLG | Same electrical specs; tape-and-reel packaging (S00Z = bulk), identical DO-35 case and marking | No functional difference; differs only in packaging format and reel quantity | Select 1N5252BRLG for automated SMT assembly; choose 1N5252B_S00Z for manual prototyping or low-volume through-hole builds |
| BZX55C24 | 24 V, 5%, 500 mW Zener; same DO-35 package but ±5% tolerance and +0.085 %/°C TC (vs. +0.088 %/°C) | Identical use cases; minor TC variance negligible in non-critical temperature environments | Prefer BZX55C24 if sourcing from European distributors or requiring RoHS-compliant variant with identical footprint |
Compared with 1N5252B_S00Z, 1N5252BRLG offers identical performance in tape-and-reel form for pick-and-place lines, while BZX55C24 provides equivalent regulation capability with marginally tighter TC control and alternate regional compliance documentation - both require no layout change but differ in logistics and certification alignment.

FAQ
What is the nominal Zener voltage of the 1N5252B_S00Z?
The 1N5252B_S00Z has a nominal Zener voltage of 24 V, with a guaranteed range of 22.8 V (min) to 25.2 V (max) at 20 mA test current and 25°C ambient temperature. This value is measured under thermal equilibrium conditions with 3/8" lead length and 30°C ± 1°C lead temperature, per ON Semiconductor's characterization methodology for the 1N5221B–1N5263B family.
Does the 1N5252B_S00Z have polarity markings, and how is the cathode identified?
Yes, the 1N5252B_S00Z uses a single color band on the DO-35 glass body to denote the cathode terminal. This marking aligns with JEDEC DO-204AH standards and is visible at one end of the axial package. The anode is the unmarked lead. Correct orientation is essential for proper reverse-bias operation in regulation or clamping roles.
What is the maximum power dissipation rating for the 1N5252B_S00Z, and how does it change with temperature?
The 1N5252B_S00Z is rated for 500 mW power dissipation at 25°C ambient. Above 50°C, it derates linearly at 4.0 mW/°C - meaning at 75°C ambient, maximum allowable dissipation drops to 400 mW. This derating ensures junction temperature remains within the −65°C to +200°C operating range and prevents thermal runaway.
Can the 1N5252B_S00Z be used as a forward-biased diode, and what is its forward voltage specification?
Yes, the 1N5252B_S00Z functions as a standard silicon diode in forward bias. Its forward voltage is specified as ≤1.2 V at 200 mA forward current. This characteristic supports dual-use applications such as reverse-polarity protection or low-current rectification where the same component serves both regulation and conduction roles.
How does the temperature coefficient of the 1N5252B_S00Z affect its performance in precision circuits?
The 1N5252B_S00Z has a temperature coefficient of +0.088 %/°C, meaning its Zener voltage increases by approximately 21.1 mV per °C rise in junction temperature. In precision circuits, this requires inclusion in total error budgets - for example, a 50°C junction rise adds ~1.06 V to VZ, necessitating thermal shielding or compensation techniques where sub-1% regulation accuracy is required.
