Product details
Overview
TSZU52C3V9 RGG from Taiwan Semiconductor is a surface-mount 3.9 V Zener diode in 0603 package, rated for 150 mW power dissipation, 5 mA test current, and 95 Ω dynamic impedance at 5 mA, used for precision voltage regulation in low-power analog circuits and reference biasing.
For engineers reviewing the TSZU52C3V9 RGG datasheet, TSZU52C3V9 RGG pinout, TSZU52C3V9 RGG application, or TSZU52C3V9 RGG equivalent, key selection criteria include zener voltage tolerance (±5%), leakage current at 1.0 V (≤10 µA), junction temperature range (–55°C to +125°C), and RoHS/halogen-free compliance for consumer and industrial PCBs.
Technical Context
This device operates as a single-die, cathode-banded Zener diode with gold-plated solderable terminals per MIL-STD-750 Method 2026. It delivers stable reverse breakdown at 3.71–4.10 V with 95 Ω dynamic impedance at 5 mA and exhibits ≤10 µA leakage at 1.0 V reverse bias.
The 0603 case supports high-density mounting and thermal derating down to zero power at +125°C ambient. Its thin, leadless construction enables compatibility with standard reflow profiles while maintaining ±5% voltage tolerance across –55°C to +125°C 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 |
|---|---|---|---|
| BZX584-C3V9 | Same 3.9 V nominal, 150 mW rating, but SOD-523 package (1.3 × 0.8 mm); 100 Ω ZZT at 5 mA | Smaller footprint but lower thermal mass; less suitable for sustained 150 mW dissipation in high-ambient environments | Select when board space is critical and peak power is intermittent |
| MMBZ5227BS | 3.9 V, 200 mW rating, SOT-323 package; 90 Ω ZZT at 20 mA test current (not 5 mA) | Higher power handling and different test condition; requires recalculation of regulation current for equivalent performance | Select when higher continuous power margin is required and layout allows larger 2.1 × 1.3 mm footprint |
Compared with BZX584-C3V9 and MMBZ5227BS, TSZU52C3V9 RGG offers tighter voltage tolerance (±5% vs ±6%), lower leakage (≤10 µA vs ≤50 µA), and optimized 5 mA test point matching typical low-power reference designs - making it preferred for precision biasing where stability and quiescent current matter most.

FAQ
What is the exact zener voltage range for TSZU52C3V9 RGG?
The TSZU52C3V9 RGG has a guaranteed zener voltage range of 3.71 V to 4.10 V at a test current of 5 mA, corresponding to a ±5% tolerance around the nominal 3.9 V rating. This specification is verified per Taiwan Semiconductor's G2009 datasheet and applies across the full operating junction temperature range of –55°C to +125°C. The TSZU52C3V9 RGG maintains this voltage window under specified thermal and current conditions without deviation.
Is TSZU52C3V9 RGG RoHS and halogen-free compliant?
Yes, TSZU52C3V9 RGG is fully RoHS compliant and halogen-free in accordance with IEC 61249-2-21. The device uses gold-plated terminals and lead-free materials throughout its 0603 construction, meeting global environmental directives for consumer and industrial electronics. This compliance is explicitly stated in the official Taiwan Semiconductor documentation for the TSZU52C3V9 RGG product family.
What is the maximum leakage current for TSZU52C3V9 RGG at 1.0 V reverse bias?
The maximum leakage current for TSZU52C3V9 RGG at 1.0 V reverse bias is 10 µA, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is measured at TA = 25°C and represents the upper limit for standby current draw in low-power bias networks. The TSZU52C3V9 RGG consistently meets this spec across production lots and temperature ranges.
Can TSZU52C3V9 RGG be used in place of TSZU52C3V6 RGG?
No - TSZU52C3V9 RGG and TSZU52C3V6 RGG are distinct parts with non-interchangeable zener voltages: TSZU52C3V6 RGG is rated 3.42–3.78 V, while TSZU52C3V9 RGG is rated 3.71–4.10 V. Their 3.6 V vs 3.9 V nominal values result in different regulation points and cannot be substituted without circuit-level validation. Always verify target voltage requirements before selecting either TSZU52C3V6 RGG or TSZU52C3V9 RGG.
What is the package dimension and terminal finish of TSZU52C3V9 RGG?
The TSZU52C3V9 RGG uses a 0603 surface-mount package measuring 1.6 mm × 0.8 mm with a maximum height of 0.5 mm. Its terminals are gold-plated and solderable per MIL-STD-750 Method 2026, supporting both SnPb and lead-free reflow processes. The cathode is marked by a visible band, and the total device weight is approximately 3.00 mg - all confirmed in the Mechanical Data section of the official TSZU52C3V9 RGG datasheet.
