Product details
Overview
BZG03C24TR from Vishay Semiconductors is a glass-passivated, surface-mount Zener diode rated for 24 V nominal Zener voltage (22.8–25.6 V), 3 W steady-state power dissipation at 100 °C ambient with RthJA < 25 K/W, and 600 W non-repetitive surge capability (100 µs pulse). It serves as a precision voltage reference and overvoltage clamp in DC power rails of industrial control modules.
For engineers reviewing the BZG03C24TR datasheet, BZG03C24TR pinout, BZG03C24TR application, or BZG03C24TR equivalent, key selection criteria include its DO-214AC package compatibility with 5 mm SMD footpads, ±5% Zener tolerance, 7 Ω typical dynamic resistance at 50 mA test current, and RoHS-compliant lead-free construction.
Technical Context
The BZG03C24TR operates as a two-terminal voltage-regulating device relying on controlled reverse-breakdown conduction. Its glass-passivated junction ensures stable Zener characteristics across temperature and long-term reliability under repeated thermal cycling.
Thermal performance is defined by junction-to-lead resistance of 25 K/W and junction-to-ambient resistance ranging from 100 K/W (on Al2O3 ceramic) to 150 K/W (on epoxy-glass PCB), directly impacting maximum allowable continuous power at given board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.8 V min / 24 V typ / 25.6 V max at IZT = 50 mA - defines clamping threshold in overvoltage protection circuits |
| Dynamic Resistance (rzj) | 7 Ω typ / 15 Ω max at IZT = 50 mA - determines regulation stiffness and output impedance under load transients |
| Power Dissipation (Pdiss) | 3 W at Tamb = 100 °C with RthJA < 25 K/W - sets maximum continuous DC power handling on thermally optimized PCBs |
| Surge Power (PZSM) | 600 W for 100 µs pulse - enables transient suppression of ESD or inductive kick without failure |
| Reverse Leakage (IR) | ≤1 µA at VR = 18 V - ensures minimal standby current in high-impedance bias networks |
| Temperature Coefficient (TKVZ) | +0.06 %/K typ / +0.11 %/K max - quantifies Zener voltage drift per degree Celsius rise in junction temperature |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | TVS diode (unidirectional), 24 V standoff, 300 W peak pulse power, higher leakage (≤100 µA @ 19.4 V) | Designed for fast transient suppression (ns response), not precision regulation | Select when surge immunity > voltage accuracy; avoid where low leakage or tight VZ tolerance is required |
| BZX84-C24 | SOT-23 package, 24 V Zener, 300 mW Pdiss, 20 Ω rzj, ±5% tolerance | Lower power, smaller footprint; unsuitable for >100 mA continuous current | Choose only for space-constrained low-power bias networks; not a drop-in replacement for BZG03C24TR's 3 W capability |
Compared with SMBJ24A and BZX84-C24, the BZG03C24TR uniquely balances 3 W continuous dissipation, 7 Ω dynamic resistance, and DO-214AC manufacturability-making it optimal for industrial 24 V rail stabilization where both precision and ruggedness are required.

FAQ
What is the Zener voltage tolerance of the BZG03C24TR?
The BZG03C24TR has a Zener voltage range of 22.8 V (minimum) to 25.6 V (maximum) at 50 mA test current, corresponding to ±5% tolerance around the nominal 24 V rating. This tolerance is guaranteed across the full operating temperature range and is verified per Vishay Document Number 85593 Rev. 1.7.
Can the BZG03C24TR be used in reflow soldering processes?
Yes, the BZG03C24TR is qualified for both wave and reflow soldering per J-STD-020. Its DO-214AC package and glass-passivated junction withstand peak reflow temperatures up to 260 °C for 10 seconds, making it compatible with standard lead-free assembly lines.
What is the maximum continuous power dissipation for BZG03C24TR at 50 °C ambient?
At 50 °C ambient temperature with RthJA < 100 K/W, the BZG03C24TR supports 1.25 W continuous power dissipation. This value scales inversely with thermal resistance-achieving 3 W only when RthJA is reduced below 25 K/W via copper pour or ceramic substrate.
Does the BZG03C24TR meet RoHS requirements?
Yes, the BZG03C24TR is lead (Pb)-free and complies with EU Directive 2002/95/EC (RoHS) and 2002/96/EC (WEEE). Vishay confirms no ozone-depleting substances were used in its manufacture, as documented in their ODS Policy Statement (Document 91000).
How does the dynamic resistance of BZG03C24TR affect voltage regulation accuracy?
The BZG03C24TR's typical dynamic resistance of 7 Ω means a 10 mA change in Zener current causes approximately 70 mV shift in clamped voltage. This low rzj ensures minimal regulation error under varying load conditions, critical for precision reference applications.
