Product details
Overview
HZK6CLTR-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 5.8–6.4 V at 0.5 mA test current, with dynamic resistance ≤60 Ω, 400 mW power dissipation, and operates across –55°C to +175°C storage temperature range. It is used in precision reference circuits for industrial sensor signal conditioning.
For engineers reviewing the HZK6CLTR-S-E datasheet, HZK6CLTR-S-E pinout, HZK6CLTR-S-E application, or HZK6CLTR-S-E equivalent, key selection criteria include zener voltage tolerance (Grade C), low dynamic impedance, thermal stability, surface-mount LLD package compatibility, and compliance with Renesas Standard-grade quality classification for industrial equipment.
Technical Context
The HZK6CLTR-S-E functions as a two-terminal voltage reference device relying on controlled reverse-biased avalanche breakdown in a silicon PN junction. Its zener voltage exhibits a positive temperature coefficient of +2.0 mV/°C (typical) within its operating range, enabling predictable drift compensation in stable bias networks.
It is rated for DC operation only, with maximum reverse current limited to 1 µA at VR = 2.0 V and specified dynamic resistance measured at IZ = 0.5 mA. The device is not intended for surge suppression or transient clamping - its design targets steady-state regulation in low-current analog references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.4 V at IZ = 0.5 mA - defines tight regulation window for 6 V reference designs |
| Dynamic Resistance (rd) | ≤60 Ω at IZ = 0.5 mA - ensures minimal output voltage variation under load changes |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact PCB layouts with adequate copper area |
| Reverse Current (IR) | ≤1 µA at VR = 2.0 V - guarantees low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 175°C maximum - enables reliable operation in thermally constrained industrial enclosures |
| Temperature Coefficient (γZ) | +2.0 mV/°C - allows predictable voltage drift modeling for calibration compensation |
Pinout & Package
The HZK6CLTR-S-E is housed in an LLD (Leadless Low-profile Diode) surface-mount package - a 2-pin, cathode-band-marked, epoxy-molded case measuring 1.4 mm diameter × 3.5 mm length, mass ≈ 0.027 g. It is JEDEC- and JEITA-unregistered but standardized per Renesas HZK-L Series mechanical drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode band side) | Cathode | Connected to regulated output node; reverse-biased terminal where zener breakdown occurs |
| 2 (Opposite end) | Anode | Connected to ground or lower-potential rail; completes bias path for reference current |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 60 Ω max ensures <10 mV output shift per 0.6 mA load change - critical for ADC reference stability |
| Grade C zener voltage tolerance | ±0.3 V total spread (5.8–6.4 V) enables binning-aware circuit margining without trimming |
| LLD surface-mount package | 1.4 mm Ø × 3.5 mm L footprint supports high-density layout and reflow-compatible assembly |
| Wide temperature operation | –55°C to +175°C storage range allows use in automotive engine-control modules and industrial motor drives |
Applications
| Industrial Sensor Signal Conditioning | Programmable Logic Controller (PLC) Analog Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | Zener voltage 3.3 V (fixed), 200 mW Pd, SOT-23 package, ±5% tolerance | Lower voltage grade; unsuitable for 6 V reference needs; better for 3.3 V logic monitoring | Select only if system requires 3.3 V regulation and SOT-23 footprint compatibility |
| BZX84-C6V2 | Zener voltage 6.2 V (nominal), 350 mW Pd, SOT-23, ±5% tolerance (≈ ±0.31 V) | Similar VZ center but wider tolerance band; higher rd (≤90 Ω); lacks Grade C binning | Acceptable for non-critical 6.2 V references where ±0.3 V margin suffices and LLD footprint is not required |
Compared with MMBZ5226BS-7-F and BZX84-C6V2, the HZK6CLTR-S-E provides tighter Grade C voltage binning (5.8–6.4 V), lower dynamic resistance (≤60 Ω), and higher power rating (400 mW), making it preferable for precision industrial analog references where stability and thermal headroom are prioritized over package miniaturization.

FAQ
What is the zener voltage range of the HZK6CLTR-S-E?
The HZK6CLTR-S-E has a guaranteed zener voltage range of 5.8 V to 6.4 V when tested at IZ = 0.5 mA, corresponding to Grade C binning per the Renesas HZK-L Series datasheet Rev.3.00. This range reflects factory-sorted units meeting tighter tolerance than standard ±5% Zeners, supporting precision reference designs without external trimming.
Is the HZK6CLTR-S-E RoHS compliant?
Yes, the HZK6CLTR-S-E complies with the EU RoHS Directive as confirmed by Renesas Electronics' environmental documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and is rated for Standard-grade applications including industrial equipment and office electronics.
What is the package type and dimensions of the HZK6CLTR-S-E?
The HZK6CLTR-S-E uses the LLD (Leadless Low-profile Diode) package: cylindrical, 1.4 mm ±0.1 mm diameter, 3.5 mm length, with cathode identified by a colored band. Its mass is approximately 0.027 g, and it is designed for reflow soldering on standard FR-4 PCBs with recommended 15 × 20 × 1.6 mm glass-epoxy mounting area.
Can the HZK6CLTR-S-E be used in automotive applications?
No - the HZK6CLTR-S-E is classified as a Renesas Standard-grade product, qualified for industrial, office, and consumer equipment per Quality Grade definitions. It is not approved for automotive use (which requires High Quality grade), nor for safety-critical or life-support systems (Specific grade). Automotive deployment requires formal qualification and written consent from Renesas Electronics.
What is the maximum reverse current specification for the HZK6CLTR-S-E?
The HZK6CLTR-S-E specifies a maximum reverse current (IR) of 1 µA at VR = 2.0 V, measured at Ta = 25°C. This low leakage supports high-impedance bias networks in precision analog circuits, such as those feeding op-amp inputs or ADC reference dividers where current draw must remain below 100 nA to avoid error accumulation.
