Product details
Overview
1N5232B_T50A from ON Semiconductor is a 5.6 V ±5% Zener diode in DO-35 glass package, rated for 500 mW power dissipation at 25°C, with 11 Ω dynamic impedance at 20 mA test current and 5.0 μA maximum reverse leakage at 4.0 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog and power supply feedback circuits.
For engineers reviewing the 1N5232B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.6 V nominal Zener voltage, tight 5% tolerance, low 11 Ω Zener impedance, temperature coefficient of +0.038 %/°C, and DO-35 hermetically sealed glass package suitability for stable biasing in industrial sensor interfaces and linear regulator references.
Technical Context
This device operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its Zener voltage is specified at IZ = 20 mA with thermal equilibrium at lead temperature (TL = 30°C ±1°C), and it exhibits a positive temperature coefficient (+0.038 %/°C) indicating voltage increases with junction temperature.
The 1N5232B_T50A is designed for DC voltage regulation and waveform clipping in low-current (<20 mA) applications. Its DO-35 glass package provides hermetic sealing and meets JEDEC DO-204AH standards, supporting reliable operation from –65°C to +200°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, min 5.32 V / max 5.88 V at IZ = 20 mA - defines stable regulation point for feedback or reference use |
| Zener Impedance (ZZ) | 11 Ω at IZ = 20 mA - low dynamic resistance ensures minimal output voltage variation under load changes |
| Power Dissipation (PD) | 500 mW at TA = 25°C, derated 4.0 mW/°C above 50°C - sets maximum continuous operating power in ambient conditions |
| Reverse Leakage (IR) | ≤5.0 μA at VR = 4.0 V - confirms low off-state current critical for high-impedance bias networks |
| Temperature Coefficient (TC) | +0.038 %/°C - quantifies voltage drift per degree rise, enabling thermal error budgeting in precision circuits |
| Package | DO-35 glass case with cathode band - hermetically sealed, JEDEC-compliant, 0.137 g weight, suitable for wave/solder reflow |
Pinout & Package
DO-35 glass axial package: hermetically sealed, 2.0 mm diameter × 4.56 mm length, cathode indicated by color band on body. Leads are tinned copper-clad steel, 0.46 mm diameter, 25.4 mm minimum straight length (T50).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground node | Connected to circuit ground or lower potential side; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener breakdown terminal / voltage reference output | Marked with color band; connected to regulated node or feedback input; carries reverse current during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables predictable regulation without post-manufacture trimming in cost-sensitive consumer and industrial designs |
| Low 11 Ω dynamic impedance | Minimizes output voltage deviation under varying load currents, improving stability in voltage reference paths |
| Hermetic DO-35 glass package | Ensures long-term parameter stability and moisture resistance in harsh environments without conformal coating |
| +0.038 %/°C temperature coefficient | Supports accurate thermal drift modeling in temperature-critical applications like sensor signal conditioning |
Applications
| Voltage Reference for Op-Amp Circuits | Overvoltage Clamp in Microcontroller I/O Protection |
|---|---|
Use Scenario: Providing stable 5.6 V reference to op-amp non-inverting input in precision instrumentation amplifiers. IC Role / Device Role / Timing Role: Zener diode acts as passive, two-terminal voltage reference source establishing fixed bias point. Use Value: Delivers <±1% total error over temperature when combined with 1% resistors, eliminating need for active reference ICs. | Use Scenario: Shunting transient overvoltage on 5 V GPIO lines before ESD protection diodes in embedded controllers. IC Role / Device Role / Timing Role: Zener diode functions as crowbar element clamping voltage to 5.6 V during fast transients. Use Value: Limits peak voltage to safe margin below MCU absolute maximum rating (6.0 V), preventing latch-up or gate oxide damage. |
| Feedback Node in Linear Regulator | Threshold Detection in Battery Monitoring |
Use Scenario: Setting output voltage of adjustable LDO (e.g., LM317) via resistor divider anchored to 1N5232B_T50A cathode. IC Role / Device Role / Timing Role: Zener diode replaces standard 1.25 V reference, enabling higher, stable output setpoint. Use Value: Enables precise 5.6 V output with <0.5% line/load regulation, avoiding external reference IC cost and board space. | Use Scenario: Detecting battery discharge threshold in 4-cell NiMH pack (nominal 4.8 V) using comparator with 1N5232B_T50A as reference. IC Role / Device Role / Timing Role: Zener diode supplies fixed 5.6 V reference to comparator's inverting input for hysteresis-free trip point. Use Value: Triggers low-battery alert at consistent 5.32–5.88 V window, independent of supply rail fluctuations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | Same 5.6 V nominal rating but ±5% tolerance, 15 Ω ZZ, DO-41 package (larger, higher thermal mass) | Higher power handling (1.0 W) but less suitable for space-constrained PCBs requiring DO-35 footprint | Select 1N4734A only if >500 mW dissipation or manual soldering robustness is required. |
| BZX55-C5V6 | Same 5.6 V / ±5%, 10 Ω ZZ, DO-35 package, but tighter 2 μA IR @ 4.0 V and –0.05 %/°C TC | Better low-leakage performance for ultra-low-power sensor biasing; negative TC enables compensation in mixed-sign drift systems | Choose BZX55-C5V6 when sub-μA leakage or thermal compensation is prioritized over ON Semiconductor supply chain alignment. |
Compared with 1N4734A and BZX55-C5V6, the 1N5232B_T50A offers optimal balance of DO-35 form factor, 11 Ω impedance, and +0.038 %/°C TC for general-purpose 5.6 V regulation-making it preferred for compact industrial control boards where thermal drift direction matches system compensation strategy.

FAQ
What is the Zener voltage tolerance and test condition for the 1N5232B_T50A?
The 1N5232B_T50A has a Zener voltage tolerance of ±5%, specified as 5.32 V (min) to 5.88 V (max) at IZ = 20 mA and thermal equilibrium at lead temperature TL = 30°C ±1°C. This tolerance reflects manufacturing spread under standardized test conditions and must be validated in the final application circuit.
Does the 1N5232B_T50A have a defined forward voltage specification?
Yes-the 1N5232B_T50A specifies a maximum forward voltage (VF) of 1.2 V at forward current IF = 200 mA. This value applies only during forward conduction and is not relevant to Zener regulation mode, which operates in reverse bias.
Can the 1N5232B_T50A be used in surface-mount designs?
No-the 1N5232B_T50A uses a DO-35 axial glass package with radial leads, intended for through-hole mounting. It is not compatible with SMT reflow or pick-and-place processes. For SMT equivalents, consider ON Semiconductor's NSZ5V6AXV6T1G or similar SOD-123 devices.
What is the maximum allowable junction temperature for the 1N5232B_T50A?
The 1N5232B_T50A has an operating junction temperature range of –65°C to +200°C. This rating assumes proper thermal management; actual junction temperature depends on ambient conditions, PCB copper area, and power dissipation. Derating begins above 50°C ambient at 4.0 mW/°C.
How does the temperature coefficient of the 1N5232B_T50A affect circuit performance?
The 1N5232B_T50A has a temperature coefficient of +0.038 %/°C, meaning its Zener voltage increases by approximately 2.13 mV/°C near 5.6 V. This positive drift must be accounted for in precision references-e.g., a 50°C rise adds ~107 mV, requiring compensation in high-stability applications.
