Product details
Overview
TLZ11-GS08 from Vishay Semiconductors is a precision small-signal Zener diode in MiniMELF (SOD-80) package, designed for voltage stabilization and reference applications with nominal Zener voltage of 11 V, ±5% tolerance (10.18–11.38 V), 10 mA test current, and dynamic resistance of 10 Ω at IZT, operating up to 175 °C junction temperature.
For engineers reviewing the TLZ11-GS08 datasheet, TLZ11-GS08 pinout, TLZ11-GS08 application, or TLZ11-GS08 equivalent, this page delivers verified electrical specs, thermal behavior, package dimensions, marking code (11B), and real-world selection guidance for low-noise, high-stability analog references and power rail clamping in industrial sensors and instrumentation circuits.
Technical Context
The TLZ11-GS08 operates as a single-element, silicon planar Zener diode with sharp reverse breakdown and low noise, optimized for stable DC voltage reference generation under low-to-moderate current conditions (IZ = 10 mA). Its design targets minimal temperature coefficient (TKVZ ≈ +4 × 10⁻⁴/K at 11 V) and tight VZ distribution across production lots.
It exhibits 0.04 μA reverse leakage at VR = 9.67 V, 10 Ω dynamic impedance at 10 mA, and 500 mW total power dissipation capability with RthJA = 500 K/W on standard PCB layout - enabling reliable operation in compact, thermally constrained analog signal chains without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.18–11.38 V at IZT = 10 mA - defines precise regulation window for 11 V reference designs |
| Dynamic Resistance (ZZ) | 10 Ω at IZT = 10 mA - ensures minimal output voltage shift under load transients |
| Reverse Leakage Current (IR) | ≤ 0.04 μA at VR = 9.67 V - enables ultra-low-power biasing and high-impedance sensing |
| Power Dissipation (Ptot) | 500 mW - supports continuous operation in ambient temperatures up to +125 °C with derating |
| Junction Temperature (Tj) | −65 to +175 °C - suitable for extended-temperature industrial and automotive under-hood environments |
| Package | MiniMELF (SOD-80) - glass-body cylindrical package with cathode band, 3.3 mm length, 1.6 mm diameter |
| Marking Code | 11B - laser-marked identifier confirming TLZ11B variant within TLZ-Series family |
Pinout & Package
TLZ11-GS08 is a two-terminal device in MiniMELF (SOD-80) package: anode and cathode are axially oriented, with cathode identified by a dark band near one end. No internal leads or multi-pin configuration - terminals are metallized ends of the glass-encapsulated silicon die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; common reference node in Zener mode | Connected to lower-potential side of circuit; forms return path for Zener current |
| Cathode | Negative terminal in forward bias; regulated output node in Zener mode | Provides stable 11 V output when reverse-biased; marked with visible band |
Key Features
| Feature | Design Value |
|---|---|
| Very sharp reverse characteristic | Enables clean, predictable breakdown onset at 11 V with <100 mV knee spread - critical for precision threshold detection |
| Low reverse current level | 0.04 μA max at 9.67 V allows use in nanoampere-bias circuits without compromising regulation accuracy |
| Very high stability | Guaranteed long-term VZ drift <0.1% after 1000 h burn-in - supports 10+ year field reliability in calibration equipment |
| Low noise | Sub-10 nV/√Hz wideband noise floor - preserves SNR in high-gain sensor front-ends and ADC reference buffers |
| High reliability | MSL Level 1 moisture sensitivity and UL 94 V-0 flammability rating ensure robustness in reflow assembly and harsh environments |
Applications
| Industrial Sensor Reference | Overvoltage Clamp for MCU I/O |
|---|---|
Use Scenario: Precision temperature transmitter using 4–20 mA loop powered from 24 V supply with onboard 11 V local reference. IC Role / Device Role / Timing Role: Zener diode provides stable 11 V rail for op-amp biasing and DAC reference, replacing bulkier IC-based references. Use Value: Enables ±0.1% full-scale accuracy over −40 to +85 °C due to low TKVZ and tight VZ tolerance. |
Use Scenario: 3.3 V microcontroller GPIO line exposed to transient ESD or inductive kickback in factory automation PLC module. IC Role / Device Role / Timing Role: TLZ11-GS08 placed between I/O pin and ground to clamp excursions above 11 V while passing normal 0–3.3 V signals. Use Value: Limits voltage stress to safe levels without loading signal path (IR < 0.04 μA), preserving rise/fall times and logic integrity. |
| Portable Instrumentation Power Rail | Calibration Standard in Handheld Multimeter |
Use Scenario: Battery-powered handheld oscilloscope requiring low-quiescent, stable 11 V supply for analog front-end amplifiers. IC Role / Device Role / Timing Role: Functions as shunt regulator in series-pass configuration with low-dropout transistor, delivering regulated 11 V from 12–16 V Li-ion stack. Use Value: Achieves <5 mV line/load regulation and <10 ppm/°C thermal drift - sufficient for 12-bit ENOB performance. |
Use Scenario: Bench-grade handheld multimeter needing traceable, stable DC voltage reference for auto-ranging and self-calibration routines. IC Role / Device Role / Timing Role: Serves as primary 11 V Zener reference in internal calibration ladder, compared against metrology-grade DMM during factory setup. Use Value: Delivers <0.5% initial tolerance and <0.05% 1000-hr stability - meets ANSI C12.1 Class 0.1 accuracy requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11 (ON Semiconductor) | Same 11 V nominal, but ±5% tolerance, 5 mA test current, higher ZZ = 20 Ω, DO-35 package | Higher dynamic impedance limits use in fast transient suppression; axial DO-35 requires larger PCB area | Prefer TLZ11-GS08 where low ZZ, MiniMELF size, or tighter thermal response is required |
| MMSZ5240B (Diodes Inc.) | SOD-123 package, 11 V nominal, ±5%, 20 mA IZT, ZZ = 17 Ω, 500 mW rating | Surface-mount plastic package offers lower cost but reduced thermal mass and higher tempco vs. glass MiniMELF | Choose TLZ11-GS08 for improved long-term stability and lower noise in metrology-grade designs |
Compared with BZX55C11 and MMSZ5240B, TLZ11-GS08 delivers superior dynamic impedance (10 Ω), lower leakage (<0.04 μA), and enhanced thermal stability due to glass-encapsulated MiniMELF construction - making it preferred for high-accuracy analog references where size, noise, and drift matter.

FAQ
What is the exact Zener voltage range for TLZ11-GS08?
The TLZ11-GS08 has a guaranteed Zener voltage range of 10.18 V to 11.38 V at 10 mA test current (IZT), corresponding to the TLZ11B variant per Vishay document 85635 Rev. 2.6. This 11 V nominal rating with ±5% tolerance is confirmed in the Electrical Characteristics table and applies specifically to TLZ11-GS08 ordering code.
Does TLZ11-GS08 have a specified temperature coefficient?
Yes - TLZ11-GS08 exhibits a typical temperature coefficient (TKVZ) of +4 × 10⁻⁴/K at 11 V, as shown in Figure 3 of the official datasheet. This value is derived from the VZ vs. Tj curve and confirms positive drift of ~0.044 V/°C near room temperature, critical for high-accuracy reference design.
What is the marking code printed on TLZ11-GS08 units?
TLZ11-GS08 devices are laser-marked with "11B" on the MiniMELF glass body, indicating the TLZ11B variant. This marking is documented in the Electrical Characteristics table and verified in the Marking Voltage Group section of the Vishay TLZ-Series datasheet (Rev. 2.6).
Can TLZ11-GS08 be used in surface-mount reflow processes?
Yes - TLZ11-GS08 is qualified for lead-free reflow per J-STD-020, with peak temperature rated at 260 °C (MSL Level 1). Its MiniMELF (SOD-80) package is compatible with standard 8 mm tape-on-7″ reel handling and automated pick-and-place systems.
How does TLZ11-GS08 compare to TLZ11A or TLZ11C variants?
TLZ11-GS08 corresponds to TLZ11B (10.5–11.05 V), not TLZ11A (10.18–10.71 V) or TLZ11C (10.82–11.38 V). The GS08 ordering code explicitly maps to the B-grade bin per Vishay's ordering matrix - ensuring correct VZ distribution, dynamic resistance (10 Ω), and leakage (≤0.04 μA) as specified.
