Product details
Overview
HZ6C3L-JTA-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 6.1–6.4 V, dynamic resistance of 60 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating of 175 °C. It serves as a stable reference in low-drift power supply feedback paths and sensor biasing networks.
For engineers reviewing the HZ6C3L-JTA-E datasheet, HZ6C3L-JTA-E pinout, HZ6C3L-JTA-E application, or HZ6C3L-JTA-E equivalent, key selection criteria include its low-noise performance (1/3–1/10 lower than standard HZ series), tight zener voltage tolerance, DO-35 package compatibility, and suitability for low-current (<1 mA) stabilized references where thermal drift and impedance stability are critical.
Technical Context
The HZ6C3L-JTA-E employs a silicon planar junction structure to minimize flicker noise and achieve consistent zener breakdown characteristics across production lots. Its low dynamic resistance (60 Ω) and low leakage current support high-precision regulation under light-load conditions typical in instrumentation front-ends and ADC reference buffers.
This device operates within a narrow zener voltage band (6.1–6.4 V) at 0.5 mA test current, with a temperature coefficient of approximately −0.04 %/°C (−2.4 mV/°C) near 6.2 V - enabling predictable drift compensation in temperature-sensitive analog stages without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.1–6.4 V at IZ = 0.5 mA - defines stable regulation point for low-power reference design |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under small load shifts |
| Power Dissipation (Pd) | 400 mW max at Ta = 25 °C - supports operation in compact PCB layouts with limited heatsinking |
| Junction Temperature (Tj) | −55 to +175 °C - enables use in industrial environments with wide ambient swings |
| Reverse Leakage (IR) | 1 μA max at VR = 2.0 V - minimizes error current in high-impedance reference nodes |
| Noise Level | ≈1/3–1/10 of standard HZ series - reduces broadband noise contribution in audio and sensor signal chains |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), glass axial leaded package with orange body and navy blue cathode band. Dimensions: φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm; mass ≈ 0.13 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated output node; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference ground return | Provides low-impedance path to circuit common; reverse-biased operation requires anode at lower potential than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener structure | Reduces RMS noise by factor of 3–10 vs. legacy HZ series - critical for sub-mV signal integrity |
| Tight VZ tolerance | ±0.15 V window at 6.25 V nominal - eliminates need for post-assembly calibration in mid-precision references |
| Low dynamic impedance | 60 Ω enables <1 mV output shift per 10 μA load change - suitable for driving op-amp inputs directly |
| High-temperature operation | Rated to 175 °C junction - supports placement near heat-generating components without derating |
| DO-35 mechanical standardization | Compatible with legacy through-hole assembly tooling and IPC-7351 footprint templates |
Applications
| Instrumentation Reference | ADC Voltage Reference |
|---|---|
Use Scenario: Precision analog front-end in portable multimeters and data loggers requiring stable 6.2 V reference under battery-powered, low-power conditions. IC Role / Device Role / Timing Role: Zener diode provides primary voltage reference for internal DAC and comparator thresholds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | Zener voltage 6.2 V ±5 %, rd = 7 Ω, Pd = 1 W, DO-41 package | Higher power handling but wider VZ tolerance and higher noise - suited for general-purpose regulation, not low-noise analog | Select only if board layout accommodates larger DO-41 footprint and system noise floor permits >3× higher diode noise |
| BZX55C6V2 | Zener voltage 6.2 V ±5 %, rd = 10 Ω, Pd = 500 mW, DO-35 package, no low-noise specification | Same package but uncharacterized noise performance and looser tempco (±0.07 %/°C) - lacks documented low-noise validation | Acceptable for cost-sensitive designs where noise is not specified, but not recommended for metrology-grade signal chains |
Compared with HZ6C3L-JTA-E, the 1N4735A offers higher power and lower impedance but sacrifices noise performance and package compatibility; the BZX55C6V2 matches the DO-35 form factor but lacks verified low-noise behavior and tighter temperature coefficient - making HZ6C3L-JTA-E the sole choice when sub-μV noise and <±0.05 %/°C drift are mandatory.

FAQ
What is the zener voltage tolerance of HZ6C3L-JTA-E?
The HZ6C3L-JTA-E has a zener voltage range of 6.1 V to 6.4 V at 0.5 mA test current, corresponding to a ±0.15 V absolute tolerance centered on 6.25 V. This tight window eliminates the need for binning or post-assembly trimming in mid-precision reference designs and is confirmed in the REJ03G0182-0300 datasheet, page 2.
Does HZ6C3L-JTA-E meet low-noise requirements for audio applications?
Yes - the HZ6C3L-JTA-E delivers approximately 1/3 to 1/10 the noise level of standard HZ-series Zeners, as stated in the "Features" section of the official Renesas datasheet. This makes it suitable for low-level audio preamplifier biasing and microphone reference circuits where diode-generated noise would otherwise degrade SNR.
What is the maximum reverse leakage current for HZ6C3L-JTA-E?
The maximum reverse leakage current (IR) for HZ6C3L-JTA-E is 1 μA at VR = 2.0 V, per the Electrical Characteristics table on page 2 of the REJ03G0182-0300 datasheet. This low leakage preserves accuracy in high-impedance reference nodes and minimizes error current in precision current sources.
Is HZ6C3L-JTA-E compatible with automated through-hole assembly?
Yes - the HZ6C3L-JTA-E uses the industry-standard DO-35 package (JEITA code GRZZ0002ZB-A) with 2.0 mm diameter and 26 mm length, fully compatible with standard axial-leaded component feeders and wave soldering profiles. The orange body color and navy blue cathode band also support optical orientation verification during placement.
What is the temperature coefficient of HZ6C3L-JTA-E?
The HZ6C3L-JTA-E exhibits a zener voltage temperature coefficient (γZ) of approximately −0.04 %/°C (or −2.4 mV/°C) near its 6.25 V nominal point, as shown in Figure 2 of the REJ03G0182-0300 datasheet. This negative, low-magnitude coefficient enables predictable drift compensation in temperature-varying analog circuits.
