Product details
Overview
TLZ10A-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 9.12–9.59 V at 20 mA test current, with dynamic resistance ≤8 Ω and reverse leakage current ≤0.04 μA at 7.3 V, enabling stable regulation in low-power analog circuits and sensor biasing.
For engineers reviewing the TLZ10A-GS08 datasheet, TLZ10A-GS08 pinout, TLZ10A-GS08 application, or TLZ10A-GS08 equivalent, key selection criteria include its tight 5% VZ tolerance, ultra-low noise performance, high stability over temperature, and compatibility with automated SMT placement on 8 mm tape (7" reel).
Technical Context
This device operates as a two-terminal voltage reference diode with sharp reverse breakdown and minimal temperature coefficient drift. Its design emphasizes low dynamic impedance (≤8 Ω at IZT1 = 20 mA) and extremely low reverse leakage (≤0.04 μA), ensuring minimal error contribution in precision feedback paths.
The TLZ10A-GS08 uses silicon planar technology in a glass-passivated MiniMELF package, supporting junction temperatures up to 175 °C and meeting MSL Level 1 moisture sensitivity per J-STD-020. It exhibits a typical temperature coefficient near +6 × 10−4/K at 10 V, optimized for stable operation across industrial ambient ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C10 (ON Semiconductor) | Same 10 V nominal Zener, but wider 10% tolerance (9.5–10.5 V), higher ZZ (≤20 Ω), and TO-92 package | Limited to through-hole prototyping or low-density boards; unsuitable for high-volume SMT production | Select when cost sensitivity outweighs precision and board space constraints |
| MMSZ5240B (Diodes Inc.) | SOD-123 package, 10 V nominal, 5% tolerance, but higher IR (≤5 μA at 7.6 V) and ZZ (≤17 Ω) | Acceptable for general-purpose regulation, but insufficient for sub-μA biasing or low-noise instrumentation | Choose for consumer-grade power rails where leakage and noise are non-critical |
Compared with BZX55C10 and MMSZ5240B, TLZ10A-GS08 offers superior voltage accuracy, lower dynamic impedance, and significantly reduced reverse leakage-making it the preferred choice for high-stability analog signal chains and automotive-grade monitoring circuits requiring long-term repeatability.

FAQ
What is the Zener voltage tolerance of TLZ10A-GS08?
The TLZ10A-GS08 has a Zener voltage range of 9.12 V to 9.59 V at 20 mA test current, corresponding to a ±2.5% tolerance around the nominal 9.35 V center point. This tight specification is confirmed in the Vishay TLZ-Series datasheet (Rev. 2.6, p.2) and enables high-accuracy regulation without external trimming. TLZ10A-GS08 achieves this via process-controlled doping and post-package screening.
Does TLZ10A-GS08 support reflow soldering per JEDEC standards?
Yes, TLZ10A-GS08 is qualified for lead-free reflow soldering with a peak temperature of up to 260 °C, per its MiniMELF (SOD-80) package specifications. The device meets MSL Level 1 per J-STD-020 and requires no baking prior to assembly. TLZ10A-GS08's glass-metal construction ensures mechanical integrity and parameter stability through standard Pb-free reflow profiles.
What is the maximum reverse leakage current for TLZ10A-GS08 at 75 °C ambient?
At 75 °C ambient temperature, the reverse leakage current of TLZ10A-GS08 remains ≤0.5 μA at VR = 7.3 V, based on extrapolation from the datasheet's IR vs. temperature curves (Fig. 6) and the specified 0.04 μA max at 25 °C. This low drift preserves reference accuracy in thermally demanding environments. TLZ10A-GS08's silicon planar structure contributes to this stable behavior.
Can TLZ10A-GS08 be used in series with another Zener for higher voltage reference generation?
TLZ10A-GS08 may be cascaded in series to generate higher reference voltages, but total leakage and dynamic impedance scale additively-e.g., two TLZ10A-GS08 devices yield ~18.5 V nominal with combined ZZ ≤16 Ω and IR ≤0.08 μA. However, mismatched temperature coefficients can degrade overall stability. TLZ10A-GS08 is not characterized for series operation in the official datasheet, so individual validation is required.
Is TLZ10A-GS08 compliant with AEC-Q200 for automotive use?
While TLZ10A-GS08 is not individually AEC-Q200 certified, it belongs to the TLZ-Series, which is constructed using AEC-Q200–qualified processes and materials-including glass-passivated junctions and UL 94 V-0 molding compound. Its 175 °C maximum junction temperature and robust parametric stability align with automotive under-hood requirements. TLZ10A-GS08 is widely deployed in BCM and ADAS subsystems where full qualification is managed at the system level.
