Product details
Overview
CSLZ5V6,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 5.6 V (min 5.3 V, max 6.0 V) at 5 mA test current, with dynamic impedance of 30 Ω, clamp voltage of 9 V at 2.5 A peak pulse current, and total capacitance of 35 pF at 1 MHz - enabling ESD and surge protection in USB, I²C, and sensor interfaces.
For engineers reviewing the CSLZ5V6,L3F datasheet, CSLZ5V6,L3F pinout, CSLZ5V6,L3F application, or CSLZ5V6,L3F equivalent, key selection criteria include its 150 mW steady-state power rating (on 20 mm × 20 mm PCB), ±30 kV contact ESD immunity per IEC61000-4-2, 32 W peak pulse power per IEC61000-4-5, and SL2 surface-mount package with verified anode/cathode terminal mapping.
Technical Context
The CSLZ5V6,L3F operates as a bidirectional voltage clamp in reverse-biased configuration, leveraging silicon epitaxial planar junction technology for stable Zener breakdown and low leakage. Its 5.6 V nominal Zener voltage aligns with E24 series standard values, supporting interoperability with common logic-level interfaces.
It exhibits a typical dynamic resistance of 0.25 Ω and clamp voltage of 9 V under 2.5 A 8/20 μs surge pulses, with thermal resistance optimized for SL2 package mounting on standard FR-4 substrates. Reverse leakage remains ≤1.0 μA at 3.5 V, ensuring minimal standby current draw in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.3–6.0 V min–max at 5 mA; ensures robust regulation across process/temp variation in 5 V rail protection. |
| Dynamic Impedance (ZZ) | 30 Ω max at 5 mA; maintains tight voltage control during fast transients without excessive overshoot. |
| Clamp Voltage (VC) | 9 V typ at 2.5 A peak pulse (8/20 μs); limits surge energy to safe levels for downstream 5 V logic ICs. |
| Total Capacitance (Ct) | 35 pF max at 1 MHz; preserves signal integrity in high-speed data lines like I²C and UART up to ~10 Mbps. |
| ESD Withstand (Contact) | ±30 kV per IEC61000-4-2; eliminates need for additional ESD diodes in consumer-grade USB and audio ports. |
| Peak Pulse Power (PPK) | 32 W per IEC61000-4-5; handles lightning-induced surges in industrial sensor nodes and building automation interfaces. |
| Steady-State Power (PD) | 150 mW on 20 mm × 20 mm PCB; supports continuous operation in ambient temperatures up to +85°C. |
Pinout & Package
The CSLZ5V6,L3F is housed in the SL2 surface-mount package (0.2 mg typical weight), a miniature leadless chip-scale device with two terminals and no internal die attach pad. Dimensions are specified in the official Toshiba land pattern drawing (Rev.3.0.A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked) | Cathode | Connected to regulated output or protected line; polarity must be observed to enable reverse-bias clamping. |
| 2 | Anode | Connected to ground or reference potential; forms low-impedance path for surge current during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| E24-standard Zener voltage | 5.6 V nominal enables direct replacement of legacy 5.1 V/5.6 V/6.2 V Zeners without circuit redesign. |
| Low dynamic resistance | 0.25 Ω typical improves clamping precision and reduces voltage excursion during fast transients. |
| High ESD immunity | ±30 kV contact discharge tolerance eliminates external ESD protection in cost-sensitive consumer electronics. |
| Low capacitance | 35 pF maximum avoids signal degradation in 3.3 V/5 V digital interfaces operating up to 10 Mbps. |
| SL2 package footprint | Enables high-density layout on space-constrained PCBs such as wearables and IoT edge sensors. |
Applications
| USB 2.0 Data Line Protection | I²C Bus Interface Protection |

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 |
|---|---|---|---|
| BZX584-C5V6 | Higher 500 mW PD rating but larger SOD-523 package; 100 pF Ct vs. 35 pF. | Less suitable for >1 Mbps data lines due to higher capacitance; better for power-rail clamping. | Select BZX584-C5V6 only when higher steady-state power dissipation is required and layout space allows larger footprint. |
| MMBZ5221BS | Same SL2 package; 5.1 V nominal VZ, 100 pF Ct, lower 20 kV ESD rating. | Acceptable for basic ESD-only protection but insufficient for combined ESD/surge scenarios per IEC61000-4-5. | Choose MMBZ5221BS only for cost-driven, low-risk consumer applications where 32 W surge handling is not required. |
Compared with BZX584-C5V6 and MMBZ5221BS, the CSLZ5V6,L3F uniquely balances ultra-low capacitance (35 pF), high ESD immunity (±30 kV), and certified 32 W surge capability in the compact SL2 package - making it optimal for high-speed, space-constrained, and standards-compliant interface protection.

FAQ
What is the Zener voltage tolerance of CSLZ5V6,L3F?
The CSLZ5V6,L3F has a Zener voltage range of 5.3 V (minimum) to 6.0 V (maximum) at 5 mA test current, corresponding to ±5% tolerance around the nominal 5.6 V value. This aligns with E24 series standardization and ensures compatibility with 5 V logic systems where ±10% supply margin is typical. The specification is guaranteed per Toshiba's production test conditions at Ta = 25°C.
Does CSLZ5V6,L3F support bidirectional ESD protection?
Yes, the CSLZ5V6,L3F functions as a bidirectional transient voltage suppressor due to its symmetrical Zener breakdown characteristics in reverse bias and low forward voltage drop (~0.9 V at 10 mA). Its ±30 kV contact ESD rating per IEC61000-4-2 applies equally to both polarities, making it suitable for protecting differential data lines like USB D+/D− without polarity-sensitive placement.
What is the thermal resistance of CSLZ5V6,L3F under standard mounting conditions?
The CSLZ5V6,L3F has a junction-to-ambient thermal resistance (Rth(j-a)) of approximately 833°C/W when mounted on a 20 mm × 20 mm glass epoxy PCB with 4 mm × 4 mm copper pads, derived from its 150 mW power rating and 150°C maximum junction temperature. This value assumes natural convection and no forced airflow, and is critical for derating calculations in enclosed or high-temperature environments.
Can CSLZ5V6,L3F replace standard 1N4734A Zener diodes?
No - the CSLZ5V6,L3F is not a drop-in replacement for through-hole 1N4734A due to fundamental differences in package (SL2 surface-mount vs. DO-41), power rating (150 mW vs. 1 W), and application focus (transient clamping vs. DC voltage regulation). While both have ~5.6 V VZ, the CSLZ5V6,L3F's low capacitance and high ESD rating make it unsuitable for high-power linear regulation but ideal for high-speed interface protection.
Is CSLZ5V6,L3F RoHS compliant and halogen-free?
Yes, the CSLZ5V6,L3F complies with EU RoHS Directive 2011/65/EU and is halogen-free per Toshiba's environmental specifications. Lead-free soldering compatibility is confirmed for reflow profiles up to JEDEC J-STD-020D moisture sensitivity level 1, and full compliance documentation is available via Toshiba's official product page and material declarations.
