Product details
Overview
1N5230B_S00Z from ON Semiconductor is a 4.7 V ±5% Zener diode in DO-35 glass package, rated for 500 mW power dissipation at 25°C, with 19 Ω dynamic impedance at 20 mA test current and 5.0 μA maximum reverse leakage at 3.76 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog circuits, power supply feedback loops, and sensor signal conditioning stages.
For engineers reviewing the 1N5230B_S00Z datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance, temperature coefficient (±0.03%/°C), thermal derating (4.0 mW/°C above 50°C), cathode identification via color band, and DO-35 mechanical compatibility with through-hole PCB layouts.
Technical Context
This device operates in reverse breakdown mode to maintain stable voltage regulation across varying load currents. Its 4.7 V nominal Zener voltage is specified at IZ = 20 mA with ±5% tolerance and a low temperature coefficient of ±0.03%/°C, enabling stable performance over -65°C to +200°C junction temperature range.
The 1N5230B_S00Z features 19 Ω dynamic impedance (ZZ) at 20 mA and 1,900 Ω knee impedance (ZZK) at 0.25 mA, supporting both high-accuracy regulation and low-current biasing. Reverse leakage remains ≤5.0 μA at 3.76 V (80% of VZ), ensuring minimal quiescent power loss in standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.465–4.935 V @ 20 mA; defines regulated output voltage in shunt regulator or reference applications |
| Power Dissipation (PD) | 500 mW @ TA = 25°C; sets maximum continuous power handling before thermal shutdown or degradation |
| Dynamic Impedance (ZZ) | 19 Ω @ 20 mA; determines voltage variation under load changes-lower value improves regulation accuracy |
| Reverse Leakage (IR) | ≤5.0 μA @ 3.76 V; ensures minimal current draw in off-state, critical for battery-powered systems |
| Temperature Coefficient | ±0.03%/°C; enables predictable VZ drift over temperature-suitable for industrial-grade references |
| Junction Temperature Range | -65°C to +200°C; supports operation in harsh environments including automotive under-hood and industrial controls |

Applications
| Power Supply Feedback Reference | Sensor Signal Level Clamping |
|---|---|
Use Scenario: Used in the feedback divider of a 5 V switching regulator to stabilize output voltage against line/load variations. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 4.7 V threshold for error amplifier comparison. Use Value: Maintains ±1% output regulation over temperature and aging due to low TC and tight VZ tolerance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4732A | 5.1 V nominal, ±5%, 1000 mW rating, 17 Ω ZZ, higher power but different VZ | Requires resistor recalculations in feedback networks targeting 4.7 V; better suited for 5 V systems | Select when higher power margin or 5.1 V reference is required; not drop-in for 4.7 V designs |
| BZX55-C4V7 | Same 4.7 V nominal, ±5%, DO-35, but 500 mW rating and 19 Ω ZZ; tighter IR spec (≤2.0 μA @ 3.76 V) | Identical electrical function and footprint; preferred where lower leakage is critical | Valid alternative with identical VZ, ZZ, and package-verify sourcing continuity for long-term production |
Compared with 1N5230B_S00Z, the 1N4732A offers higher power and 5.1 V regulation but requires circuit redesign, while BZX55-C4V7 matches all key parameters and improves leakage performance-making it the most direct functional alternative for 4.7 V reference use cases.

FAQ
What is the Zener voltage tolerance and test condition for 1N5230B_S00Z?
The 1N5230B_S00Z has a Zener voltage tolerance of ±5%, specified as 4.465 V (min) to 4.935 V (max) at a test current of 20 mA and ambient temperature of 25°C. This tolerance reflects manufacturing variation and must be accounted for in precision reference designs using the 1N5230B_S00Z.
Does 1N5230B_S00Z have a specified forward voltage?
Yes, the 1N5230B_S00Z has a maximum forward voltage of 1.2 V at 200 mA forward current. This parameter is relevant when the device is used bidirectionally-for example, as an ESD clamp-where forward conduction limits positive transients while reverse breakdown regulates negative excursions.
What is the thermal derating behavior of 1N5230B_S00Z above 50°C?
The 1N5230B_S00Z derates linearly at 4.0 mW/°C above 50°C ambient temperature. At 75°C, its maximum allowable power dissipation drops to 400 mW (500 mW − [25 × 4.0 mW]), ensuring safe operation without exceeding junction temperature limits in enclosed or high-temperature environments.
How is cathode polarity marked on the 1N5230B_S00Z DO-35 package?
The cathode of the 1N5230B_S00Z is marked by a single color band (typically black or dark gray) located near one end of the DO-35 glass body. This band identifies the cathode terminal, which must be connected to the higher-potential node in Zener regulation applications-correct orientation is essential for proper 1N5230B_S00Z functionality.
Is 1N5230B_S00Z suitable for automotive under-hood applications?
Yes, the 1N5230B_S00Z supports an operating junction temperature range of -65°C to +200°C and is housed in a hermetically sealed DO-35 glass package, meeting requirements for under-hood automotive use. However, system-level qualification per AEC-Q200 is not claimed-designers must validate 1N5230B_S00Z performance in their specific thermal and vibration environment.
