Product details
Overview
HZK11CLTR-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage regulation and stabilization in low-power supply circuits. It delivers a nominal zener voltage of 10.9–11.9 V at 0.5 mA test current, with dynamic resistance ≤80 Ω, maximum power dissipation of 400 mW, and operates within –55°C to +175°C storage temperature range. It is used in precision reference circuits for industrial sensors and analog front-ends.
For engineers reviewing the HZK11CLTR-S-E datasheet, HZK11CLTR-S-E pinout, HZK11CLTR-S-E application, or HZK11CLTR-S-E equivalent, key selection criteria include zener voltage tolerance (±5% Grade C), low leakage (<1 µA at VR = 2.0 V), thermal stability (temperature coefficient ~+8.0 mV/°C), and LLD surface-mount package compatibility with high-density PCB layouts.
Technical Context
The HZK11CLTR-S-E belongs to the HZK-L Series, engineered as a discrete silicon Zener diode using epitaxial planar construction for stable reverse-breakdown behavior. Its junction temperature rating of 175°C supports operation in thermally demanding environments, and its DC-tested electrical characteristics ensure predictable regulation under steady-state bias.
This device functions exclusively in reverse-bias mode, with zener voltage specified at IZ = 0.5 mA and dynamic resistance measured at the same current. The LLD package enables automated placement and reflow soldering, and its two-terminal configuration eliminates control logic or external bias requirements.
Key Specifications

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 |
|---|---|---|---|
| BZX84-C11LT1G | Same nominal VZ (10.4–11.6 V), SOT-23 package, Pd = 300 mW, rd ≤ 100 Ω | Lower power rating limits use in >10 mA clamp applications; smaller footprint reduces thermal mass | Select when board space is constrained and peak dissipation remains <300 mW |
| MMSZ5240BT1G | VZ = 10 V (9.5–10.5 V), SOD-123 package, Pd = 500 mW, rd ≤ 17 Ω | Narrower voltage tolerance but lower impedance; higher power enables robust transient clamping | Choose for tighter regulation at higher currents where 10 V setpoint is acceptable |
Compared with BZX84-C11LT1G and MMSZ5240BT1G, the HZK11CLTR-S-E offers superior thermal endurance (175°C Tj) and tighter Grade C voltage spread (10.9–11.9 V), making it preferred for industrial environments requiring long-term stability under thermal cycling.

FAQ
What is the exact zener voltage range for HZK11CLTR-S-E?
The HZK11CLTR-S-E has a guaranteed zener voltage range of 10.9 V to 11.9 V when tested at IZ = 0.5 mA, corresponding to Grade C specification per the Renesas HZK-L Series datasheet Rev.3.00. This tolerance band reflects ±5% deviation around the nominal 11.4 V center point and is validated under DC test conditions.
Is HZK11CLTR-S-E RoHS compliant?
Yes, HZK11CLTR-S-E complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, and is suitable for lead-free reflow soldering processes.
What is the maximum reverse leakage current for HZK11CLTR-S-E?
The maximum reverse leakage current for HZK11CLTR-S-E is 1 µA when measured at VR = 2.0 V, per the Electrical Characteristics table in the official Renesas datasheet. This low leakage supports energy-efficient operation in battery-powered monitoring circuits where standby current must remain sub-microampere.
Can HZK11CLTR-S-E be used in place of HZK11BL or HZK11AL?
No - HZK11CLTR-S-E is not a direct replacement for HZK11BL or HZK11AL due to differing voltage tolerances: Grade C (10.9–11.9 V) vs. Grade B (10.2–11.1 V) vs. Grade A (9.5–10.3 V). Substituting across grades alters regulation accuracy and may violate system-level voltage margin requirements without circuit revalidation.
What does the "TR-S-E" suffix indicate in HZK11CLTR-S-E?
The "TR-S-E" suffix in HZK11CLTR-S-E denotes tape-and-reel packaging (TR), standard reliability grade (S), and environmental compliance (E) per Renesas' ordering nomenclature. It confirms the device ships in EIA-481-compliant 7-inch reels with 3,000 units per reel and meets RoHS and halogen-free requirements.
