Product details
Overview
HZ6C1LTD-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 5.8–6.1 V, dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It is widely deployed in regulated power supplies, sensor excitation circuits, and ADC reference buffers where noise-sensitive operation is critical.
For engineers reviewing the HZ6C1LTD-E datasheet, HZ6C1LTD-E pinout, HZ6C1LTD-E application, or HZ6C1LTD-E equivalent, key selection criteria include its low-noise performance (≈1/3–1/10 of standard HZ series), tight zener voltage tolerance, DO-35 package compatibility, and suitability for stable DC biasing in instrumentation-grade designs.
Technical Context
This device operates as a two-terminal, reverse-biased voltage reference with a specified zener breakdown region between 5.8 V and 6.1 V at 0.5 mA test current. Its low dynamic resistance (60 Ω) ensures minimal output impedance under varying load conditions, while its low leakage current (<1 μA at VR = 2.0 V) supports high-impedance node stabilization.
The HZ6C1LTD-E exhibits a zener voltage temperature coefficient of approximately −0.04 %/°C (−2.4 mV/°C) near 6 V, enabling predictable drift compensation in ambient-temperature-varying environments. Its DO-35 glass package provides hermetic sealing and thermal stability suitable for industrial-grade PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.1 V at IZ = 0.5 mA - defines stable reference point for precision biasing and regulation. |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures low output impedance and minimal voltage shift under load transients. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact layouts without forced cooling. |
| Junction Temperature (Tj) | −55 to +175°C - enables use in extended-temperature industrial and automotive under-hood applications. |
| Reverse Leakage (IR) | ≤1 μA at VR = 2.0 V - preserves accuracy in high-impedance reference networks and battery-powered systems. |
| Noise Level | ≈1/3–1/10 of standard HZ series - directly reduces RMS noise in sensitive analog front-ends and sensor signal chains. |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), axial-leaded glass encapsulation with navy-blue cathode band; body color orange; mass ≈0.13 g; dimensions per SC-40 standard (φD = 2.0 mm, L = 26.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-side terminal of reverse-biased junction | Connected to positive rail in shunt regulator configuration; determines polarity and voltage reference direction. |
| 2 (Anode) | Low-side terminal of reverse-biased junction | Typically grounded or tied to lowest system potential; completes current path during zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise performance | Reduces RMS voltage noise by up to 90% vs. legacy HZ series-critical for high-resolution data acquisition. |
| Tight zener voltage tolerance | ±0.15 V window (5.8–6.1 V) enables accurate calibration without post-production trimming. |
| Low dynamic impedance | 60 Ω ensures <1 mV output shift under ±1 mA load variation-ideal for driving op-amp inputs or ADC references. |
| Hermetic DO-35 packaging | Provides long-term parameter stability and moisture resistance in humid or thermally cycling environments. |
| High junction temperature rating | 175°C Tj allows reliable operation in enclosed enclosures or near heat-generating components. |
Applications

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 |
|---|---|---|---|
| ON Semiconductor MMBZ5226BS | Zener voltage 3.3 V, SOD-123 package, 200 mW Pd, rd = 17 Ω - lower voltage, smaller package, lower power. | Best suited for low-voltage logic-level clamping or 3.3 V rail stabilization-not interchangeable for 6 V reference needs. | Select only when target reference voltage and surface-mount footprint align; not a drop-in replacement for HZ6C1LTD-E. |
| Vishay BZX84-C6V2 | Zener voltage 6.2 V, SOT-23 package, 300 mW Pd, rd = 70 Ω - slightly higher VZ, plastic package, higher dynamic impedance. | Acceptable for general-purpose 6.2 V regulation but lacks the ultra-low-noise performance required in metrology-grade designs. | Consider for cost-sensitive, non-critical applications where noise floor and long-term drift are secondary concerns. |
Compared with MMBZ5226BS and BZX84-C6V2, the HZ6C1LTD-E delivers superior noise suppression and higher power handling in a through-hole DO-35 format-making it the preferred choice for industrial and test equipment demanding stable, low-drift 6 V references.

FAQ
What is the zener voltage range of the HZ6C1LTD-E?
The HZ6C1LTD-E has a guaranteed zener voltage range of 5.8 V to 6.1 V when tested at a zener current of 0.5 mA. This tight tolerance supports accurate voltage referencing without external trimming, and the value is validated per Renesas REJ03G0182-0300 Rev.3.00 specification. The HZ6C1LTD-E maintains this performance across its rated operating temperature range.
Does the HZ6C1LTD-E have a specified temperature coefficient?
Yes-the HZ6C1LTD-E exhibits a typical zener voltage temperature coefficient of −0.04 %/°C (approximately −2.4 mV/°C) near its 6 V operating point, as shown in Figure 2 of the official Renesas datasheet. This negative coefficient is consistent with mid-voltage Zener devices and enables predictable drift compensation in thermal-aware designs using the HZ6C1LTD-E.
Is the HZ6C1LTD-E compatible with lead-free reflow soldering processes?
The HZ6C1LTD-E uses a DO-35 glass package with axial leads that comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for through-hole assembly. While not classified as MSL-rated like SMD packages, its glass body and metallization support standard wave and hand-soldering profiles-including lead-free (260°C peak) processes-without degradation, as confirmed in Renesas reliability testing for the HZ-L Series.
How does the noise performance of the HZ6C1LTD-E compare to standard Zener diodes?
The HZ6C1LTD-E achieves approximately 1/3 to 1/10 the noise level of conventional HZ-series Zener diodes, as explicitly stated in the Renesas HZ-L Series datasheet features. This ultra-low-noise characteristic stems from optimized silicon planar construction and process controls-directly improving signal integrity in applications such as precision ADC references and low-level sensor excitation where the HZ6C1LTD-E is deployed.
What is the maximum power dissipation rating for the HZ6C1LTD-E?
The HZ6C1LTD-E is rated for a maximum power dissipation of 400 mW at an ambient temperature of 25°C, as defined in the Absolute Maximum Ratings table of the Renesas REJ03G0182-0300 datasheet. Derating is required above 25°C per the published curve in Figure 3, with zero dissipation reached at ~150°C ambient-ensuring safe operation in thermally constrained industrial environments using the HZ6C1LTD-E.
