Product details
Overview
HZK11BLTL-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage regulation and stabilization in low-power supply rails. It delivers a nominal zener voltage of 10.2–11.1 V at 5 mA, with dynamic resistance ≤25 Ω, maximum power dissipation of 500 mW, and operates within a junction temperature range of –55°C to +175°C. It is used in precision reference circuits and feedback loops of DC-DC converters.
For engineers reviewing the HZK11BLTL-S-E datasheet, HZK11BLTL-S-E pinout, HZK11BLTL-S-E application, or HZK11BLTL-S-E equivalent, key selection criteria include its ±5% zener voltage tolerance (Grade B), low leakage current (≤1 µA at VR = 7.5 V), surface-mount LLD package compatibility, and thermal stability across industrial ambient temperatures.
Technical Context
The HZK11BLTL-S-E employs a planar epitaxial structure to achieve stable breakdown characteristics and low zener impedance. Its graded doping profile ensures predictable reverse conduction onset and minimal voltage drift under varying current loads.
It is optimized for DC-stabilized operation with specified test conditions at IZ = 5 mA and VR = 7.5 V. The device exhibits a zener voltage temperature coefficient of approximately +5.5 mV/°C (typical for ~11 V devices), confirmed by Figure 2 in the official datasheet.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 10.2–11.1 V at IZ = 5 mA - defines regulated output voltage range in shunt regulator topologies. |
| Dynamic Resistance (rd) | ≤25 Ω at IZ = 5 mA - determines load regulation sensitivity and ripple rejection capability. |
| Maximum Power Dissipation | 500 mW - sets upper thermal limit for continuous DC operation on standard PCBs. |
| Reverse Leakage Current | ≤1 µA at VR = 7.5 V - ensures minimal quiescent current in standby or high-impedance bias networks. |
| Junction Temperature Range | –55°C to +175°C - supports deployment in extended-temperature industrial environments without derating. |
| Package Type | LLD - ultra-compact surface-mount package (1.4 mm Ø) enabling high-density PCB layouts. |

Use Value: Enables ±0.5 LSB accuracy retention across –40°C to +85°C ambient due to characterized γZ and low hysteresis. |
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 |
|---|---|---|---|
| 1N4740A | 10 V nominal, ±5%, 1 W power rating, DO-41 through-hole package | Higher power handling but larger footprint; less suitable for space-constrained SMT designs | Select when board layout permits through-hole mounting and >500 mW dissipation margin is required. |
| BZX55C10 | 10 V nominal, ±5%, 500 mW, DO-35 glass package with axial leads | Same power rating but non-SMT; lacks LLD's automated assembly compatibility and thermal mass advantage | Choose only if legacy DO-35 footprint must be retained and reflow process is not available. |
Compared with 1N4740A and BZX55C10, the HZK11BLTL-S-E offers identical voltage-grade performance in a smaller, lighter, and fully SMT-compatible LLD package-critical for modern miniaturized power management modules where board area and assembly efficiency are constrained.

FAQ
What is the exact zener voltage range for HZK11BLTL-S-E?
The HZK11BLTL-S-E has a guaranteed zener voltage range of 10.2 V to 11.1 V when tested at IZ = 5 mA and Ta = 25°C. This Grade B specification reflects ±4.5% tolerance around the nominal 10.65 V midpoint, as defined in the Renesas HZK Series datasheet Rev.3.00.
Does HZK11BLTL-S-E support reflow soldering?
Yes, the HZK11BLTL-S-E uses the LLD package-a glass-body surface-mount device qualified for standard lead-free reflow profiles per J-STD-020. Its 175°C maximum junction temperature and 0.027 g mass ensure reliable thermal cycling performance without cracking or delamination during PCB assembly.
What is the maximum reverse leakage current for HZK11BLTL-S-E?
The maximum reverse leakage current for HZK11BLTL-S-E is 1 µA at VR = 7.5 V and Ta = 25°C. This low leakage supports high-impedance bias networks and minimizes standby power loss in battery-operated systems using the HZK11BLTL-S-E as a reference element.
Is HZK11BLTL-S-E RoHS compliant?
Yes, HZK11BLTL-S-E complies with the EU RoHS Directive (2011/65/EU) and contains no restricted substances above allowable thresholds. Renesas confirms compliance in product change notifications and material declarations applicable to the HZK Series as of manufacturing date codes post-2006.
Can HZK11BLTL-S-E replace HZK11A or HZK11C in existing designs?
No-HZK11BLTL-S-E corresponds specifically to Grade B (10.2–11.1 V), whereas HZK11A (9.5–10.3 V) and HZK11C (10.9–11.9 V) have non-overlapping voltage ranges. Substituting across grades risks regulation error or insufficient headroom; the HZK11BLTL-S-E must be used only where Grade B specifications are validated in the target circuit.
