Product details
Overview
CSLZ10V,L3F from Toshiba Electronic Devices & Storage Corporation is a silicon epitaxial planar Zener diode designed for voltage regulation and transient overvoltage clamping in low-power signal lines. It delivers a nominal Zener voltage of 10 V (min 9.4 V, typ 10 V, max 10.6 V) at 5 mA test current, with dynamic impedance of 30 Ω max, 0.5 Ω typical dynamic resistance, and 18 V clamp voltage under 2.5 A peak pulse current per IEC61000-4-5.
For engineers reviewing the CSLZ10V,L3F datasheet, CSLZ10V,L3F pinout, CSLZ10V,L3F application, or CSLZ10V,L3F equivalent, key selection criteria include its 150 mW steady-state power dissipation on small PCB pads, ±30 kV ESD robustness per IEC61000-4-2 (contact), 16 pF total capacitance at 1 MHz, and suitability for space-constrained surge protection in USB, I²C, and sensor interface circuits.
Technical Context
The CSLZ10V,L3F operates as a precision shunt regulator with stable Zener breakdown behavior across temperature, leveraging Toshiba's silicon epitaxial planar process for tight voltage tolerance (±6% around 10 V) and low dynamic impedance. Its ESD and surge performance is characterized per IEC61000-4-2 (±30 kV contact) and IEC61000-4-5 (60 W peak pulse power, 2.5 A IPP).
Designed for surface-mount use in ultra-compact layouts, it features a low-profile SOD-323 (SC-90) package with 0.2 mg typical weight and standardized land pattern dimensions. The device maintains junction temperature up to 150°C and supports storage from −55°C to +150°C, enabling deployment in industrial and automotive-adjacent environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4–10.6 V at IZ = 5 mA - ensures reliable clamping within ±6% tolerance for 10 V rail protection |
| Dynamic Impedance (ZZ) | ≤30 Ω at IZ = 5 mA - minimizes voltage deviation during transient current surges |
| Clamp Voltage (VC) | 18 V at IPP = 2.5 A (8/20 μs) - defines maximum voltage seen by protected IC during surge events |
| Total Capacitance (Ct) | 16 pF at VR = 0 V, f = 1 MHz - preserves signal integrity on high-speed data lines like I²C and UART |
| ESD Withstand (Contact) | ±30 kV per IEC61000-4-2 - eliminates need for external ESD diodes in cost-sensitive consumer interfaces |
| Steady-State Power (PD) | 150 mW on 4 mm × 4 mm pad - enables thermal design on standard FR-4 without heatsinking |
| Junction Temperature (Tj) | 150°C max - supports operation in enclosed enclosures or near heat-generating components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation and surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B10,115 (Nexperia) | Same SOD-323 package, 10 V nominal, but 400 mW PD, 22 pF Ct, ±30 kV ESD (air only) | Higher power rating suits higher-energy transients; higher capacitance limits use on >1 Mbps buses | Choose for higher surge energy handling where board space allows minor capacitance trade-off |
| MMBZ5240BLT1G (onsemi) | SOD-123 package, 10 V nominal, 350 mW PD, 30 pF Ct, ±30 kV ESD (contact) | Larger footprint and higher capacitance reduce suitability for dense USB/I²C layouts | Select when existing layout uses SOD-123 footprints or when higher steady-state power margin is prioritized over size |
Compared with BZX384-B10,115 and MMBZ5240BLT1G, the CSLZ10V,L3F offers the lowest capacitance (16 pF) in the SOD-323 form factor and superior contact-mode ESD robustness (±30 kV), making it optimal for miniaturized, high-speed interface protection where signal fidelity and compactness are critical.

FAQ
What is the Zener voltage tolerance of CSLZ10V,L3F?
The CSLZ10V,L3F has a Zener voltage range of 9.4 V (minimum) to 10.6 V (maximum) at 5 mA test current, corresponding to ±6% tolerance around the nominal 10 V rating. This aligns with the E24 resistor series and ensures predictable clamping behavior in production designs without requiring binning or calibration.
Does CSLZ10V,L3F meet IEC61000-4-5 surge immunity requirements?
Yes, the CSLZ10V,L3F is rated for 60 W peak pulse power and 2.5 A peak pulse current under IEC61000-4-5 (8/20 μs waveform), with a measured clamp voltage of 18 V. This enables compliance with Level 3 (1 kV line-to-ground) surge testing when properly laid out with low-inductance grounding paths.
What is the thermal resistance and maximum operating temperature of CSLZ10V,L3F?
The CSLZ10V,L3F has a maximum junction temperature of 150°C and a storage temperature range of −55°C to +150°C. Its thermal resistance depends on PCB layout: 200 K/W on a 4 mm × 4 mm copper pad (for 150 mW rating) and 75 K/W on a larger 645 mm² pad (enabling 400 mW derated operation).
Can CSLZ10V,L3F be used in place of a standard 1N4740A Zener diode?
No-CSLZ10V,L3F is not a drop-in replacement for the through-hole 1N4740A. It uses an SOD-323 surface-mount package, has lower power rating (150 mW vs. 1 W), and is optimized for ESD/surge clamping rather than continuous voltage regulation. Use CSLZ10V,L3F where size, speed, and transient immunity matter-not for high-power DC regulation.
Is CSLZ10V,L3F RoHS compliant and halogen-free?
Yes, CSLZ10V,L3F complies with EU RoHS Directive 2011/65/EU and is halogen-free per Toshiba's environmental specifications. Full compliance documentation-including substance declarations and test reports-is available upon request from Aetrix Electronics for qualifying customers.
