Product details
Overview
TSZU52C3V6 RGG from Taiwan Semiconductor is a surface-mount 3.6 V ±5% Zener diode in 0603 package, rated for 150 mW power dissipation, 5 mA test current, and 95 Ω dynamic impedance at IZT, used for precision voltage reference and low-power regulation in space-constrained consumer and industrial circuits.
For engineers reviewing the TSZU52C3V6 RGG datasheet, TSZU52C3V6 RGG pinout, TSZU52C3V6 RGG application, or TSZU52C3V6 RGG equivalent, key selection criteria include zener voltage tolerance (±5%), low leakage current (15 µA @ 1.0 V), gold-plated solderable terminals, RoHS/halogen-free compliance, and 0603 footprint compatibility with automated assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its cathode–anode terminals under varying load conditions. It exhibits a nominal zener voltage of 3.6 V with ±5% tolerance, specified at 5 mA test current and 25°C ambient temperature.
Its electrical behavior is characterized by 95 Ω dynamic impedance at 5 mA, 15 µA leakage current at 1.0 V reverse bias, and a maximum junction temperature of +125°C. The device uses a single-die configuration in an ultra-thin, leadless 0603 ceramic package with cathode band polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.42 V to 3.78 V - defines stable regulation point under 5 mA test current |
| Power Dissipation (PD) | 150 mW - maximum continuous power handling at 25°C ambient |
| Dynamic Impedance (ZZT) | 95 Ω @ 5 mA - determines output voltage stability under small-signal current variation |
| Leakage Current (IR) | 15 µA @ 1.0 V reverse bias - critical for low-power standby and battery-backed circuits |
| Junction Temperature Range | −55°C to +125°C - supports operation in extended industrial environments |
| Package Size | 0603 (1.6 mm × 0.8 mm) - enables high-density PCB layout and reflow-compatible assembly |
Pinout & Package
TSZU52C3V6 RGG is a two-terminal surface-mount Zener diode in JEDEC-standard 0603 package. Polarity is marked by a cathode band on the component body; terminal 1 (cathode) connects to the regulated output node, terminal 2 (anode) to ground or return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Regulated voltage output node | Connected to load or reference point; maintains ~3.6 V relative to anode when reverse-biased above breakdown |
| Anode | Reference/return path | Typically tied to system ground or common return; completes reverse-bias current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-thin leadless construction | 0603 footprint (1.6 × 0.8 × 0.45 mm) enables placement in tight board spaces and compatibility with standard SMT pick-and-place |
| Gold-plated terminals | Ensures reliable solderability per MIL-STD-750 Method 2026 and long-term intermetallic joint integrity |
| RoHS and halogen-free compliance | Meets IEC 61249-2-21 and global environmental directives without compromising thermal or electrical performance |
| Low-temperature coefficient design | Stable 3.6 V reference over −55°C to +125°C, minimizing drift in thermally variable environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 (Nexperia) | Same 3.6 V nominal, 150 mW rating, but 0402 package (1.0 × 0.5 mm); higher leakage (50 µA @ 1 V) | Higher density placement possible, but reduced thermal margin and less robust surge handling | Select for ultra-compact layouts where 0402 is preferred and leakage sensitivity is low |
| MMBZ5226BS (ON Semiconductor) | 3.6 V nominal, 200 mW rating, SOT-23 package; lower dynamic impedance (70 Ω), higher IFSM (2 A) | Requires through-hole or larger SMT footprint; better for transient-heavy environments | Select when higher surge immunity or lower impedance is required and board area permits SOT-23 |
Compared with BZX584-C3V6 and MMBZ5226BS, TSZU52C3V6 RGG offers optimal balance of 0603 footprint compatibility, 15 µA low-leakage performance, and gold-plated solderability-making it ideal for high-yield, fine-pitch consumer electronics production.

FAQ
What is the exact zener voltage range for TSZU52C3V6 RGG?
The TSZU52C3V6 RGG has a guaranteed zener voltage range of 3.42 V to 3.78 V at 5 mA test current and 25°C ambient temperature, representing ±5% tolerance around the nominal 3.6 V rating. This specification is verified per Taiwan Semiconductor's G2009 datasheet revision and applies strictly to the TSZU52C3V6 RGG variant-not the broader TSZU52C family.
Is TSZU52C3V6 RGG compatible with lead-free reflow soldering processes?
Yes, TSZU52C3V6 RGG features gold-plated terminals qualified per MIL-STD-750 Method 2026 and is fully compatible with standard lead-free reflow profiles (peak temperature up to 260°C). Its 0603 ceramic body and thin-film construction ensure reliable wetting and joint formation without tombstoning or delamination.
What is the maximum allowable reverse leakage current for TSZU52C3V6 RGG?
The maximum reverse leakage current for TSZU52C3V6 RGG is 15 µA when biased at 1.0 V reverse voltage, as specified in the Electrical Specifications table of the official datasheet. This value is measured at 25°C and remains valid across the full operating temperature range (−55°C to +125°C) with typical degradation below 2× at max junction temperature.
Does TSZU52C3V6 RGG have a defined polarity marking, and how is it identified?
Yes, TSZU52C3V6 RGG uses a visible cathode band on the top surface of the 0603 body to indicate polarity. The banded end is the cathode terminal and must be connected toward the higher-potential node (e.g., regulated output or signal line), while the unmarked end is the anode, typically grounded. This marking complies with JEDEC standards for surface-mount diodes.
Can TSZU52C3V6 RGG be used in place of older through-hole Zener diodes like 1N4728A?
No-TSZU52C3V6 RGG is not a direct replacement for 1N4728A due to fundamental differences: it is a 150 mW 0603 SMD device versus the 1W through-hole 1N4728A. While both regulate near 3.6 V, TSZU52C3V6 RGG lacks the power handling and thermal mass for equivalent load conditions. Use only in low-power, space-constrained designs where 150 mW suffices.
