Product details

Overview

TLZ10-GS08 from Vishay Semiconductors is a precision small-signal Zener diode in MiniMELF (SOD-80) package, designed for voltage stabilization and reference applications. It delivers a nominal Zener voltage of 10 V with ±5% tolerance (9.12–10.44 V), operates at 20 mA test current, exhibits low dynamic resistance of 8 Ω, and maintains reverse leakage current ≤0.04 μA at 7.5 V.

For engineers reviewing the TLZ10-GS08 datasheet, TLZ10-GS08 pinout, TLZ10-GS08 application, or TLZ10-GS08 equivalent, key selection criteria include its tight V_Z tolerance, ultra-low IR, stable temperature coefficient (≈+5.5 × 10⁻⁴/K near 10 V), and suitability for low-noise analog references and precision power-supply feedback loops.

Technical Context

The TLZ10-GS08 belongs to the TLZ-Series family of silicon planar Zener diodes optimized for sharp reverse breakdown and high long-term stability. Its junction construction enables low noise and minimal voltage drift over time and temperature.

It operates within a 500 mW total power dissipation limit, supports junction temperatures up to 175 °C, and features a thermal resistance of 500 K/W on standard PCB layout (50 mm × 50 mm × 1.6 mm). The device is rated for storage from −65 °C to +175 °C and complies with MSL level 1 per J-STD-020.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	9.12–10.44 V at I_ZT = 20 mA - defines precise regulation point for feedback or reference circuits
Dynamic Resistance (Z_Z)	8 Ω max at I_ZT = 20 mA - ensures minimal output impedance and high regulation accuracy under load variation
Reverse Leakage Current (I_R)	≤0.04 μA at V_R = 7.5 V - critical for low-power bias networks and high-impedance sensing nodes
Power Dissipation (P_tot)	500 mW - sets maximum continuous DC or pulsed power handling on standard PCB layout
Junction Temperature (T_j)	−65 to +175 °C - enables operation in extended industrial and automotive under-hood environments
Package	MiniMELF (SOD-80) - cylindrical glass-body surface-mount package with cathode band marking and 31 mg mass
Forward Voltage (V_F)	1.5 V max at I_F = 200 mA - supports use as clamping or protection diode in bidirectional circuits

Pinout & Package

MiniMELF (SOD-80) is a two-terminal axial-lead surface-mount package with cathode identified by a dark band. No PCB pad layout changes are required when replacing other SOD-80 Zeners; footprint matches JEDEC DO-213AA standard.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal in forward bias; connected to lower-potential node in Zener mode	Must be held at potential ≤ (V_Z − V_F) below cathode to avoid forward conduction during regulation
Cathode	Current exit terminal in forward bias; connected to higher-potential node in Zener mode	Marked with dark band; serves as regulated output node in shunt regulator configuration

Key Features

Feature	Design Value
Very sharp reverse characteristic	Enables clean, predictable breakdown onset - essential for accurate threshold detection and low-hysteresis clamping
Low reverse leakage current	≤0.04 μA at 75% of V_Z - preserves signal integrity in high-impedance reference dividers and battery-powered sensors
High stability & low noise	Long-term V_Z drift <0.1% after 1000 hrs; low 1/f noise - suitable for metrology-grade voltage references
UL 94 V-0 molding compound	Self-extinguishing encapsulation - meets flame-retardancy requirements for industrial and transportation end equipment
MSL Level 1 rating	Unlimited floor life at ≤30 °C/60% RH - eliminates bake requirements before reflow soldering

FAQ

What is the exact Zener voltage range specified for TLZ10-GS08?

The TLZ10-GS08 has a guaranteed Zener voltage range of 9.12 V to 10.44 V at 20 mA test current (I_ZT), corresponding to a ±5% tolerance around the nominal 10 V rating. This range is confirmed in the Electrical Characteristics table on page 2 of Vishay document 85635 Rev. 2.6.

Does TLZ10-GS08 have a specified temperature coefficient, and what is its typical value?

Yes, TLZ10-GS08 exhibits a positive temperature coefficient near +5.5 × 10⁻⁴/K (or +0.055%/°C) at 10 V, as shown in Figure 3 ("Typical Temperature Coefficient of V_Z vs. Z-Voltage") in the TLZ-Series datasheet. This value ensures predictable, monotonic V_Z drift over temperature in precision reference designs.

Can TLZ10-GS08 be used in surface-mount reflow processes without moisture sensitivity concerns?

Yes, TLZ10-GS08 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60% RH and requires no baking prior to standard lead-free reflow (peak temperature ≤260 °C). Its MiniMELF (SOD-80) package uses UL 94 V-0 compliant molding compound.

What is the maximum reverse leakage current for TLZ10-GS08, and at what test condition is it measured?

The maximum reverse leakage current for TLZ10-GS08 is 0.04 μA, measured at V_R = 7.5 V (75% of nominal V_Z). This ultra-low IR is critical for minimizing error in high-impedance voltage divider networks and battery-backed reference circuits.

How does the dynamic resistance of TLZ10-GS08 impact its performance in a shunt regulator circuit?

With a maximum dynamic resistance (Z_Z) of 8 Ω at 20 mA, TLZ10-GS08 provides excellent line and load regulation-output voltage change is limited to ≤80 mV per 10 mA load step. This low Z_Z directly improves regulation accuracy in feedback paths of switching regulators and precision analog supplies.
