Product details
Overview
CSLZ8V2,L3F from Toshiba Electronic Devices & Storage Corporation is a silicon epitaxial planar Zener diode in a miniature SOD-323 (SC-90) package, rated for 8.2 V nominal zener voltage (7.7–8.7 V), 150 mW power dissipation on small PCBs, and 55 W peak pulse power per IEC61000-4-5. It serves as a transient voltage suppressor in low-voltage signal line protection circuits.
For engineers reviewing the CSLZ8V2,L3F datasheet, CSLZ8V2,L3F pinout, CSLZ8V2,L3F application, or CSLZ8V2,L3F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance (0.62 Ω), clamp voltage (17 V at 2.5 A), junction temperature limit (150°C), and ESD robustness (±30 kV contact per IEC61000-4-2).
Technical Context
This Zener diode operates in reverse breakdown to regulate or clamp voltage during transients. Its planar epitaxial structure ensures stable zener characteristics with low dynamic impedance and tight voltage tolerance aligned to E24 series values.
Designed for surge suppression in low-power analog and digital interfaces, it delivers 17 V clamping at 2.5 A (8/20 μs pulse), supports ≤6.5 μA reverse leakage at 6.5 V, and maintains operation from −55°C to +150°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B8V2,115 (Nexperia) | Same 8.2 V zener, but 200 mW PD, 100 pF Ct, ±30 kV ESD | Higher capacitance limits use to DC/low-frequency rails only | Select when higher steady-state power margin is required and bandwidth is not critical |
| MMBZ5231BS-7-F (Diodes Inc.) | 8.2 V zener, 300 mW PD, 25 pF Ct, ±15 kV ESD | Lower ESD rating; requires external ESD protection for harsh environments | Choose for cost-sensitive consumer applications where full industrial ESD is not mandated |

FAQ
What is the zener voltage tolerance of CSLZ8V2,L3F?
The CSLZ8V2,L3F has a zener voltage range of 7.7 V (minimum) to 8.7 V (maximum) at 5 mA test current, with a typical value of 8.2 V. This ±0.5 V tolerance aligns with E24 standard values and ensures predictable clamping behavior in precision voltage-reference and overvoltage-protection circuits.
Does CSLZ8V2,L3F meet IEC61000-4-5 surge immunity standards?
Yes, CSLZ8V2,L3F is rated for 55 W peak pulse power under IEC61000-4-5 (8/20 μs waveform), corresponding to Level 4 (4 kV line-to-ground) surge immunity. Its 17 V clamp voltage at 2.5 A ensures downstream circuitry remains within safe operating limits during standardized surge events.
What is the thermal resistance and power derating behavior of CSLZ8V2,L3F?
CSLZ8V2,L3F has a 150 mW power rating when mounted on a 20 mm × 20 mm glass-epoxy board with 4 mm × 4 mm copper pads. Derating begins above 25°C ambient, with full derating to zero at 150°C junction temperature. The device's 150°C max Tj enables reliable operation in enclosed industrial enclosures.
Can CSLZ8V2,L3F be used in high-frequency signal paths?
Yes, CSLZ8V2,L3F exhibits only 18 pF typical junction capacitance at 0 V and 1 MHz, making it suitable for protecting USB 2.0, I²C, and other sub-100 MHz signal lines without significant rise-time degradation or signal reflection.
How is polarity marked on the CSLZ8V2,L3F package?
The CSLZ8V2,L3F uses the SOD-323 package with a cathode band (pin 1) clearly marked on the top surface. Pin 1 is the cathode terminal and must be connected toward the voltage rail being protected; pin 2 is the anode and connects to ground or reference potential.
