Product details
Overview
HZK5CLLTR-S-E from Renesas Electronics is a silicon planar Zener diode optimized for hard-knee, low-noise voltage reference applications at 4.9–5.3 V nominal Zener voltage, with 0.5 mA test current, 380 Ω dynamic impedance (ZZT), and 50 nA reverse leakage (IR) at 0.5 V reverse bias. It serves as a precision shunt reference in analog sensor signal conditioning and low-power regulator feedback paths.
For engineers reviewing the HZK5CLLTR-S-E datasheet, HZK5CLLTR-S-E pinout, HZK5CLLTR-S-E application, or HZK5CLLTR-S-E equivalent, key selection criteria include its low-noise hard-knee Zener behavior, LLD surface-mount package compatibility with high-density PCB layouts, and stable 4.9–5.3 V regulation under sub-mA operating currents.
Technical Context
This device belongs to the HZK-LL Series, engineered specifically for low-current, low-noise Zener operation - achieving approximately 1/10 the dynamic impedance of conventional zeners in the 0.001–0.5 mA range. Its hard-knee characteristic minimizes voltage deviation across small current changes near knee region.
The diode uses silicon planar construction with controlled doping profiles to ensure tight Zener voltage tolerance (±0.2 V), low temperature coefficient (γZ ≈ ±2 mV/°C near 5 V), and stable junction temperature up to 175°C. It is not rated for automotive or safety-critical use per Renesas quality grade classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.9–5.3 V at IZ = 0.5 mA - defines stable regulation point for low-current reference designs |
| Dynamic Impedance (ZZT) | 380 Ω typical at IZT = 3.0 mA - enables low output noise and minimal load-induced voltage shift |
| Reverse Leakage (IR) | ≤100 nA at VR = 0.5 V - ensures negligible error current in high-impedance reference nodes |
| Power Dissipation (Pd) | 250 mW max on PCB - supports continuous operation in compact SMT layouts without forced cooling |
| Junction Temperature (Tj) | −55 to +175°C - allows deployment in industrial ambient environments with thermal cycling |
| Temperature Coefficient (γZ) | ≈ ±2 mV/°C near 5 V - provides predictable drift behavior for compensated reference circuits |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | 5.1 V nominal, ±5% tolerance, 600 Ω ZZT at 5 mA, 100 nA IR at 1 V | Higher dynamic impedance and looser voltage tolerance - suitable only for non-critical biasing | Choose BZX84-C5V1 only when cost sensitivity outweighs noise and regulation precision requirements. |
| MMSZ5231B | 5.1 V nominal, ±5% tolerance, 17 Ω ZZT at 20 mA, but 500 nA IR at 1 V and no hard-knee optimization | Optimized for higher-current regulation; exhibits soft knee and higher leakage below 1 mA | Select MMSZ5231B only if operating above 5 mA and noise performance is secondary to regulation stability at load. |
Compared with HZK5CLLTR-S-E, BZX84-C5V1 offers lower cost but sacrifices low-current noise and voltage accuracy, while MMSZ5231B delivers superior dynamic impedance at high current but lacks the hard-knee behavior and sub-100 nA leakage essential for micro-power reference design.

FAQ
What is the Zener voltage tolerance of HZK5CLLTR-S-E?
The HZK5CLLTR-S-E has a specified Zener voltage range of 4.9 V to 5.3 V at 0.5 mA test current, corresponding to a ±0.2 V absolute tolerance. This tight window reflects its hard-knee design and enables accurate calibration without post-production trimming. The HZK5CLLTR-S-E does not specify a percentage tolerance; its datasheet defines min/max bounds directly. Renesas characterizes this variation across production lots under standard test conditions (Ta = 25°C).
Is HZK5CLLTR-S-E suitable for automotive applications?
No, HZK5CLLTR-S-E is classified as a "Standard" quality grade device per Renesas documentation and is intended for computers, office equipment, communications gear, and industrial robots - not transportation or safety-critical systems. It lacks AEC-Q200 qualification, extended temperature validation beyond −55°C to +175°C junction, or automotive-specific reliability testing. For automotive use, Renesas recommends qualified alternatives such as the RZM series.
What is the maximum power dissipation for HZK5CLLTR-S-E on a standard PCB?
HZK5CLLTR-S-E has a maximum power dissipation (Pd) of 250 mW when mounted on a standard glass-epoxy printed circuit board, as defined in the Absolute Maximum Ratings table. This rating assumes natural convection cooling and applies at Ta = 25°C. Derating is required above 25°C ambient - approximately 2.0 mW/°C reduction per degree Celsius above ambient - to maintain safe junction temperature.
Does HZK5CLLTR-S-E have a specified temperature coefficient?
Yes, the HZK5CLLTR-S-E exhibits a Zener voltage temperature coefficient (γZ) of approximately ±2 mV/°C near its 5 V operating point, as shown in Figure 2 of the datasheet. This value is derived from measured data across the 4.9–5.3 V range and reflects typical behavior - not a guaranteed parameter. The HZK5CLLTR-S-E datasheet does not specify a min/max γZ bound, only the characteristic curve shape.
Can HZK5CLLTR-S-E replace a TL431 in feedback circuits?
HZK5CLLTR-S-E can serve as a passive Zener replacement for TL431 in simple shunt reference configurations, but it lacks the TL431's active error amplifier, adjustable threshold, and sink current capability. In feedback divider networks where only a fixed ~5 V reference is needed and load current stays below 0.5 mA, the HZK5CLLTR-S-E provides lower quiescent current and better noise performance. However, it cannot regulate dynamically or drive optocouplers directly like the TL431.
