Product details
Overview
TSZU52C30 from Taiwan Semiconductor is a surface-mount 30 V, 150 mW Zener diode in 0603 package, with zener voltage tolerance ±5% (28.5–31.5 V), dynamic impedance 80 Ω at 5 mA test current, and maximum leakage current 0.1 µA at 23 V reverse bias-used for precision voltage regulation in compact power management circuits.
For engineers reviewing the TSZU52C30 datasheet, TSZU52C30 pinout, TSZU52C30 application, or TSZU52C30 equivalent, key selection criteria include its 0603 footprint compatibility, low-leakage performance at 23 V VR, 80 Ω zener impedance at IZT = 5 mA, and operation within -55°C to +125°C junction temperature range.
Technical Context
This device operates as a single-die, cathode-banded Zener diode optimized for stable voltage reference and overvoltage clamping in space-constrained PCB layouts. Its gold-plated terminals comply with MIL-STD-750 Method 2026 and support reflow soldering.
The TSZU52C30 exhibits a temperature coefficient near zero at ~30 V (per Fig.1), maintains ≤80 Ω dynamic impedance up to 5 mA test current, and delivers <0.1 µA leakage at VR = 23 V-enabling reliable regulation in battery-powered and low-power sensor nodes.
Key Specifications

| Zener Impedance (ZZT) | 80 Ω max at IZT = 5 mA - determines regulation stiffness against load transients |
| Leakage Current (IR) | 0.1 µA max at VR = 23 V - ensures minimal standby power loss in high-impedance bias networks |
| Junction Temp Range | -55°C to +125°C - supports operation in automotive under-hood and industrial control environments |
| Package | 0603 (1.6 × 0.8 mm) - enables high-density routing and automated placement on miniaturized PCBs |

Key Features
| Feature | Design Value |
|---|---|
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS Directive - required for consumer and industrial CE-marked products |
| Extremely thin, leadless construction | 0603 footprint with <3 mg mass - reduces board stress and enables ultra-thin end-equipment designs |
| Stable zener voltage tolerance | ±5% over full operating temperature range - eliminates need for post-production trimming in cost-sensitive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C30 (Nexperia) | Same 30 V nominal, 150 mW PD, but 0805 package (2.0 × 1.25 mm); 100 Ω ZZT max | Requires PCB pad revision; slightly higher impedance reduces regulation precision under dynamic load | Select if existing 0805 land pattern is fixed and 100 Ω impedance is acceptable |
| MMSZ5248B (ON Semiconductor) | 30 V nominal, 500 mW PD, SOD-123 package; 30 Ω ZZT max; 0.1 µA IR @ 23 V | Larger footprint and higher power rating suit higher-energy clamping; not drop-in for 0603 space constraints | Prefer when surge energy absorption >150 mW is required and board area allows SOD-123 |
Compared with BZX584-C30 and MMSZ5248B, the TSZU52C30 uniquely balances 0603 miniaturization, 80 Ω regulation stiffness, and sub-µA leakage-making it optimal for space- and power-critical shunt references where 150 mW dissipation suffices.

FAQ
What is the zener voltage tolerance of TSZU52C30 at 25°C?
The TSZU52C30 has a zener voltage range of 28.5 V to 31.5 V at IZ = 5 mA and TA = 25°C, corresponding to ±5% tolerance. This specification is guaranteed per the Electrical Specifications table in the G2009 datasheet and remains valid across the full operating temperature range of -55°C to +125°C.
Does TSZU52C30 support reflow soldering, and what terminal plating does it use?
Yes, TSZU52C30 supports standard Pb-free reflow soldering profiles. Its terminals are gold-plated and qualified per MIL-STD-750, Method 2026, ensuring reliable wetting and intermetallic formation during assembly. The 0603 package is compatible with IPC-7351B land patterns for Type II solder paste deposition.
What is the maximum leakage current for TSZU52C30, and at what reverse voltage is it specified?
The maximum leakage current for TSZU52C30 is 0.1 µA, measured at VR = 23 V and TA = 25°C. This value is confirmed in the Electrical Specifications table and reflects worst-case reverse-bias behavior before breakdown onset-critical for low-power standby circuit design.
Can TSZU52C30 be used in automotive under-hood applications?
Yes, TSZU52C30 is rated for junction temperatures from -55°C to +125°C and is RoHS/halogen-free compliant. While not AEC-Q200 qualified, its thermal and electrical specs meet requirements for non-safety-critical cabin and body-control modules operating within this temperature envelope.
What packaging option is available for TSZU52C30, and how many units per reel?
TSZU52C30 is supplied in 0603 tape-and-reel packaging, with 4,000 units per 7-inch reel (ordering code: TSZU52C30RGG). The reel meets EIA-481-D standards and is compatible with Fuji CP-7 and Yamaha YSM20 pick-and-place equipment.
