Product details
Overview
TSZU52C10 from Taiwan Semiconductor is a 150 mW, 9.5–10.5 V Zener diode in a leadless 0603 surface-mount package, designed for precision voltage regulation and reference functions in space-constrained DC power rails, such as low-voltage microcontroller I/O protection and analog sensor biasing.
For engineers reviewing the TSZU52C10 datasheet, TSZU52C10 pinout, TSZU52C10 application, or TSZU52C10 equivalent, key selection criteria include its 15 mΩ dynamic impedance at 5 mA, 0.1 µA leakage at 7.5 V, 125°C max junction temperature, gold-plated solderable terminals per MIL-STD-750 Method 2026, and RoHS/halogen-free compliance.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal zener voltage of 10 V (±5%) at 5 mA test current. Its low dynamic impedance (15 Ω max at IZT = 5 mA) ensures stable regulation under varying load conditions, while its 0.1 µA leakage at VR = 7.5 V supports low-power standby circuits.
The device uses a single-die configuration in an ultra-thin 0603 ceramic package with cathode band polarity marking. It is rated for continuous operation from –55°C to +125°C junction temperature and withstands 2 A surge forward current (8.3 ms half-sine), enabling robustness in transient-prone supply lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.5–10.5 V at IZ = 5 mA - defines precise clamping threshold for 10 V reference or overvoltage protection |
| Power Dissipation (PD) | 150 mW - limits continuous thermal load in compact PCB layouts without heatsinking |
| Dynamic Impedance (ZZT) | 15 Ω max at IZT = 5 mA - ensures minimal output voltage variation under load current shifts |
| Leakage Current (IR) | 0.1 µA max at VR = 7.5 V - enables use in battery-powered circuits with ultra-low quiescent current |
| Junction Temperature (TJ) | –55°C to +125°C - supports operation in automotive under-hood and industrial control environments |
| Package | 0603 (1.6 × 0.8 mm) - compatible with standard high-speed SMT placement and reflow profiles |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - allows predictable forward conduction for dual-direction clamping or ESD path design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C10 (Nexperia) | Same 10 V nominal, 150 mW, 0603 package; 20 Ω ZZT (vs. 15 Ω), 0.5 µA IR at 7.5 V (vs. 0.1 µA) | Slightly higher leakage and impedance reduce accuracy in low-current references | Preferred when cost sensitivity outweighs sub-µA leakage or <15 Ω ZZT needs |
| MMBZ5240BLT1G (ON Semiconductor) | 10 V nominal, 200 mW, SOT-23 package; 25 Ω ZZT, 0.1 µA IR, but larger footprint and different mounting | Requires PCB redesign due to 3-pin SOT-23 vs. 2-terminal 0603; better power handling only if layout permits | Select only when thermal margin >150 mW is required and 0603 size constraint is relaxed |
Compared with BZX584C10 and MMBZ5240BLT1G, TSZU52C10 delivers the lowest dynamic impedance and tightest leakage in the 0603 form factor, making it optimal for high-accuracy, space-limited regulation where thermal headroom is constrained to 150 mW.

FAQ
What is the exact zener voltage tolerance for TSZU52C10?
The TSZU52C10 has a guaranteed zener voltage range of 9.50 V to 10.50 V at a test current of 5 mA, representing ±5% tolerance about the nominal 10 V rating. This specification is verified per Taiwan Semiconductor's G2009 datasheet revision and applies across the full operating temperature range of –55°C to +125°C.
Does TSZU52C10 support lead-free reflow soldering?
Yes, TSZU52C10 features gold-plated terminations qualified per MIL-STD-750 Method 2026 and compatible with standard lead-free reflow profiles (J-STD-020). Its ceramic 0603 package withstands peak temperatures up to 260°C for 10 seconds without degradation of electrical parameters or mechanical integrity.
What is the maximum allowable surge current for TSZU52C10?
TSZU52C10 is rated for a surge peak forward current (IFSM) of 2 A under an 8.3 ms single half-sine waveform, as specified in the Absolute Maximum Ratings table. This rating applies to forward conduction only; reverse surge capability is limited by its 150 mW power dissipation and thermal mass.
How does TSZU52C10 compare to TSZU52C10 RGG in part numbering?
TSZU52C10 is the base part number; "RGG" is the package and packing suffix indicating 0603 case size and 4,000-unit 7-inch reel packaging. No functional or parametric difference exists between TSZU52C10 and TSZU52C10 RGG - RGG denotes fulfillment format only, per Taiwan Semiconductor's Ordering Information table.
Is TSZU52C10 suitable for use as a voltage reference in precision ADC circuits?
TSZU52C10 can serve as a cost-effective reference in moderate-accuracy ADC applications (e.g., 10–12 bit), provided its ±5% VZ tolerance, 15 Ω dynamic impedance, and temperature coefficient are accommodated in system calibration. For higher precision, dedicated shunt references (e.g., TL431) are recommended, but TSZU52C10 remains viable where board space and BOM count are prioritized.
