Product details
Overview
HZK11CTR-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage regulation in stabilized power supplies. It delivers a nominal zener voltage of 10.6 V (midpoint of 10.2–11.1 V range, Grade B), with dynamic resistance of 25 Ω at 5 mA test current, maximum power dissipation of 500 mW, and operates within –55°C to +175°C storage temperature range. It is used in low-power reference circuits for industrial instrumentation and embedded power monitoring.
For engineers reviewing the HZK11CTR-S-E datasheet, HZK11CTR-S-E pinout, HZK11CTR-S-E application, or HZK11CTR-S-E equivalent, key selection criteria include its 10.2–11.1 V zener voltage tolerance (Grade B), 25 Ω dynamic impedance at 5 mA, LLD surface-mount package compatibility, thermal stability up to 175°C junction temperature, and compliance with Renesas' Standard quality grade for industrial equipment.
Technical Context
The HZK11CTR-S-E employs a silicon epitaxial planar structure optimized for low leakage and stable zener breakdown characteristics. Its design targets DC voltage reference applications requiring tight regulation under low-current conditions (IZ = 5 mA) and minimal temperature-induced drift.
It exhibits a zener voltage temperature coefficient of approximately +5.5 mV/°C (typical for ~11 V devices per Fig.2), and maintains ≤1 µA reverse current at VR = 7.5 V - confirming sharp knee behavior and suitability for low-power biasing and sensing circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11 (ON Semiconductor) | Same nominal VZ (11 V), but ±5% tolerance (10.45–11.55 V); 500 mW rating; DO-35 package (larger than LLD) | Requires PCB footprint redesign; higher leakage (≤5 µA at 8.2 V) reduces suitability for ultra-low-power nodes | Select when DO-35 through-hole assembly is preferred or legacy board reuse is required |
| MMSZ5240B (Diodes Inc.) | VZ = 10 V ±5% (9.5–10.5 V); SOD-123 package; 500 mW; rd = 30 Ω max at 20 mA | Narrower voltage range but higher test current; less suitable for low-current (<5 mA) reference use due to higher rd at low IZ | Select for cost-sensitive designs where 10 V nominal suffices and SOD-123 footprint is already standardized |
Compared with BZX55C11 and MMSZ5240B, the HZK11CTR-S-E offers tighter Grade B voltage tolerance (10.2–11.1 V), lower dynamic resistance at its specified 5 mA test current, and a smaller LLD package - making it optimal for space-constrained, low-current industrial reference designs requiring thermal robustness.

FAQ
What is the exact zener voltage range for HZK11CTR-S-E?
The HZK11CTR-S-E has a guaranteed zener voltage range of 10.2 V to 11.1 V at 5 mA test current, corresponding to Grade B specification per the Renesas HZK Series datasheet Rev.3.00. This range reflects manufacturing tolerance and ensures predictable regulation behavior in production circuits using the HZK11CTR-S-E.
Is HZK11CTR-S-E compatible with reflow soldering processes?
Yes, the HZK11CTR-S-E uses the LLD package, which is qualified for standard Pb-free reflow soldering profiles per J-STD-020. Its glass-passivated construction and 175°C maximum junction temperature support compatibility with typical peak reflow temperatures up to 260°C, making the HZK11CTR-S-E suitable for automated SMT assembly lines.
What is the maximum reverse current specification for HZK11CTR-S-E?
The HZK11CTR-S-E specifies a maximum reverse current (IR) of 1 µA when measured at VR = 7.5 V, per the Electrical Characteristics table on page 3 of the Renesas datasheet. This low leakage supports high-impedance reference node stability and is a confirmed parameter for the HZK11CTR-S-E.
Does HZK11CTR-S-E have a defined temperature coefficient?
While the HZK11CTR-S-E datasheet does not list a discrete temperature coefficient value for this specific variant, Figure 2 shows that 11 V-class HZK devices exhibit a typical zener voltage temperature coefficient of approximately +5.5 mV/°C. This behavior is inherent to the silicon epitaxial planar structure and applies directly to the HZK11CTR-S-E.
What quality grade is assigned to HZK11CTR-S-E?
The HZK11CTR-S-E is classified as a "Standard" quality grade device per Renesas Electronics' product grading system, as no alternate grade is specified in its datasheet. This qualifies the HZK11CTR-S-E for use in industrial robots, office equipment, communications gear, and other non-safety-critical applications outlined in the Renesas documentation.
