Product details

Overview

TLZ5V6C-GS08 from Vishay Semiconductors is a MiniMELF (SOD-80) packaged silicon Zener diode optimized for precision voltage regulation at 5.61–5.91 V nominal Zener voltage with 1 μA maximum reverse leakage at 2 V, 13 Ω dynamic resistance at 20 mA test current, and 500 mW total power dissipation - used in low-noise reference circuits and analog sensor biasing.

For engineers reviewing the TLZ5V6C-GS08 datasheet, TLZ5V6C-GS08 pinout, TLZ5V6C-GS08 application, or TLZ5V6C-GS08 equivalent, key selection criteria include Zener voltage tolerance (±2.7% at 20 mA), thermal stability (low temperature coefficient near zero crossing), low noise performance, and MiniMELF package compatibility with high-reliability PCB layouts requiring minimal parasitic capacitance.

Technical Context

The TLZ5V6C-GS08 operates as a two-terminal voltage reference device with sharp reverse breakdown characteristics and low dynamic impedance (13 Ω at I_ZT1 = 20 mA), enabling stable regulation under varying load conditions. Its Zener voltage exhibits near-zero temperature coefficient around 5.6 V, minimizing drift across -65 °C to +175 °C operating range.

Designed for surface-mount use in MiniMELF (SOD-80) package, it delivers high reliability with MSL level 1 moisture sensitivity rating and peak reflow tolerance up to 260 °C. The device supports pulse and DC operation with junction-to-ambient thermal resistance of 500 K/W on standard 50 mm × 50 mm × 1.6 mm PCB.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX55C5V6-TR	DO-35 package; 5.3–5.9 V range; 20 Ω Z_Z; 500 mW rating	Higher thermal resistance (650 K/W); less stable long-term drift	Acceptable for cost-sensitive consumer designs where MiniMELF mechanical robustness is not required

FAQ

What is the exact Zener voltage tolerance of TLZ5V6C-GS08 at 20 mA test current?

The TLZ5V6C-GS08 has a specified Zener voltage range of 5.61 V minimum to 5.91 V maximum at I_ZT = 20 mA, corresponding to ±2.7% tolerance about the nominal 5.76 V center point. This tight tolerance is achieved through laser trimming during final test and is guaranteed across the full -65 °C to +175 °C junction temperature range.

Does TLZ5V6C-GS08 support reflow soldering, and what are its JEDEC-compliant thermal limits?

Yes, TLZ5V6C-GS08 is qualified for lead-free reflow soldering per J-STD-020, with peak temperature tolerance up to 260 °C for ≤30 seconds. Its MiniMELF (SOD-80) package carries MSL level 1 rating - meaning unlimited floor life at ≤30 °C/60% RH - and requires no baking prior to assembly.

How does the temperature coefficient of TLZ5V6C-GS08 compare to other 5.6 V Zener diodes?

TLZ5V6C-GS08 exhibits a near-zero temperature coefficient (~0 × 10⁻⁴/K) at its 5.6 V nominal point, confirmed by Fig. 3 in the datasheet. This is superior to standard 5.1 V Zeners (typically +2.5 × 10⁻⁴/K) and avoids the positive drift seen in higher-voltage devices, making it ideal for temperature-critical references.

Can TLZ5V6C-GS08 be used in series or parallel configurations for higher voltage or current capability?

No - TLZ5V6C-GS08 is not characterized for series or parallel operation. Its Zener voltage matching tolerance and thermal coupling behavior are unspecified for multi-device configurations. For higher voltage needs, select a single higher-V_Z variant (e.g., TLZ6V2C); for higher current, use an external pass transistor driven by TLZ5V6C-GS08 as reference.

What is the maximum allowable reverse voltage before breakdown for TLZ5V6C-GS08?

The TLZ5V6C-GS08 begins controlled Zener breakdown at its specified V_Z range (5.61–5.91 V). Below this, reverse leakage remains ≤1 μA at 2 V. No absolute "maximum non-breakdown voltage" is defined - operation above V_Z is intentional and safe within P_tot = 500 mW limit. Forward voltage is rated ≤1.5 V at 200 mA.
