Product details
Overview
TSZU52C39 from Taiwan Semiconductor is a surface-mount 39 V ±7.5% zener diode in a 0603 package, rated for 150 mW power dissipation, 5 mA test current, and 90 Ω dynamic impedance at 5 mA, used for precision voltage regulation in space-constrained consumer and industrial circuits.
For engineers reviewing the TSZU52C39 datasheet, TSZU52C39 pinout, TSZU52C39 application, or TSZU52C39 equivalent, key selection criteria include zener voltage tolerance (±7.5%), low leakage current (0.1 µA at 29 V), temperature-stable operation (−55°C to +125°C), and compatibility with automated 0603 SMT assembly.
Technical Context
The TSZU52C39 operates as a single-die, cathode-banded zener diode optimized for stable reverse-breakdown regulation at 39 V nominal. Its 90 Ω dynamic impedance at 5 mA and 0.1 µA leakage at 29 V support tight voltage reference stability under light-load conditions.
Designed for reflow-compatible 0603 mounting, it features gold-plated terminals per MIL-STD-750 Method 2026 and meets RoHS and halogen-free (IEC 61249-2-21) requirements. Junction temperature is rated from −55°C to +125°C, with derated power above 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 37.05–40.95 V at 5 mA - defines regulation setpoint with ±7.5% tolerance |
| Power Dissipation (PD) | 150 mW - maximum continuous power at 25°C ambient; derates linearly above |
| Dynamic Impedance (ZZT) | 90 Ω at 5 mA - determines output voltage variation under load transients |
| Leakage Current (IR) | 0.1 µA at 29 V - ensures minimal quiescent current in standby regulation |
| Junction Temperature Range | −55°C to +125°C - supports operation in extended-temperature industrial environments |
| Package Size | 0603 (1.6 × 0.8 mm) - enables high-density PCB layouts with standard SMT placement |
Pinout & Package
Package: 0603 surface-mount, leadless, cathode indicated by band. Gold-plated terminations ensure solderability and long-term interconnect reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node during forward bias; not used in zener regulation mode |
| Cathode | Zener breakdown terminal | Connected to higher-potential node; reverse-biased to maintain regulated voltage across load |
Key Features
| Feature | Design Value |
|---|---|
| Wide zener voltage range coverage | Part of 2.0–39 V family enabling standardized BOM across multiple regulation points |
| Extremely thin, leadless construction | 0603 footprint minimizes board area and height-critical for ultra-thin portable devices |
| Low leakage current | 0.1 µA at 29 V reduces standby power loss in battery-powered systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C39 | Same 39 V nominal, 150 mW rating, but 0805 package (2.0 × 1.25 mm) | Larger footprint; less suitable for ultra-dense layouts where 0603 is mandated | Select when higher thermal mass or legacy 0805 land patterns are in use |
| MMSZ5240B | 39 V nominal, 500 mW rating, SOD-123 package; 10x higher power handling | Requires different PCB layout and thermal relief; over-specified for low-power regulation | Select only when >150 mW dissipation or higher surge robustness is required |
Compared with BZX584-C39 and MMSZ5240B, the TSZU52C39 uniquely balances 0603 miniaturization, 150 mW capability, and ±7.5% voltage tolerance-making it optimal for compact, cost-sensitive, low-power regulation where board space is constrained.
