Product details
Overview
HZK6BL-JTL from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies. It delivers a nominal zener voltage of 5.5–6.0 V (Grade B), with 40 Ω dynamic resistance at 5 mA, 500 mW power dissipation, and operates within –55°C to +175°C storage temperature range. It is used in voltage reference circuits for sensor signal conditioning and microcontroller reset supervision.
For engineers reviewing the HZK6BL-JTL datasheet, HZK6BL-JTL pinout, HZK6BL-JTL application, or HZK6BL-JTL equivalent, key selection criteria include verified zener voltage tolerance (±0.5 V), low dynamic impedance for stable regulation under load transients, LLD surface-mount package compatibility with high-density PCB layouts, and compliance with Renesas' Standard quality grade for industrial and consumer electronics.
Technical Context
The HZK6BL-JTL employs a silicon epitaxial planar junction structure optimized for low leakage current (<5 µA at VR = 0.5 V) and tight zener voltage control across production lots. Its zener voltage temperature coefficient is +2.0 mV/°C (typical for 5.8 V nominal), enabling predictable drift behavior in ambient-temperature-varying environments.
This device functions exclusively as a two-terminal shunt regulator - no biasing circuitry or external components are required for basic operation. It is not intended for surge suppression, transient clamping, or bidirectional protection; its design purpose is DC voltage stabilization at fixed current levels (5 mA test condition).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.5–6.0 V (Grade B); ensures reliable 5.5 V reference with ±0.5 V tolerance at 5 mA, suitable for 5 V system rail monitoring. |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA; minimizes output voltage variation under load current changes, critical for stable analog references. |
| Power Dissipation (Pd) | 500 mW (on PCB); supports continuous operation up to ~90°C ambient when mounted on standard FR-4 board per JEDEC guidelines. |
| Reverse Leakage (IR) | ≤5 µA at VR = 0.5 V; guarantees negligible quiescent current draw in battery-powered or low-power standby circuits. |
| Junction Temperature (Tj) | 175°C max; enables use in thermally demanding environments such as enclosed industrial controllers or automotive cabin modules. |
| Package | LLD (leadless land pattern); 1.4 mm diameter, 0.35 mm height - compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
The HZK6BL-JTL uses the LLD (Leadless Land Device) package - a cylindrical, glass-passivated silicon chip with metallized end caps for surface mounting. No leads or gull-wing terminations; cathode and anode are accessed via opposite circular faces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (band-marked face) | Reference terminal for zener breakdown | Connected to higher-potential node; reverse-biased operation requires cathode ≥ anode by VZ. |
| Anode (unmarked face) | Current return path | Typically tied to ground or common reference; completes shunt regulation loop with series resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 40 Ω max ensures <10 mV output shift per 0.4 mA load change - essential for precision analog front-ends. |
| Wide zener voltage spectrum | Part of HZK Series spanning 1.9–38 V; HZK6BL-JTL fills the 5.5–6.0 V band for 5 V logic-compatible references. |
| High-temperature operation | Rated to 175°C junction temperature - supports deployment in engine-control proximity or sealed power supply enclosures. |
| LLD surface-mount form factor | 1.4 mm Ø × 0.35 mm height enables >2× density vs. DO-35; eliminates lead coplanarity issues in fine-pitch assembly. |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Reset Supervision |

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 |
|---|---|---|---|
| BZX55C5V6 (ON Semiconductor) | 5.6 V nominal, ±5% tolerance (±0.28 V), 40 Ω rd, DO-35 package (3.5 mm length) | Through-hole mounting required; larger footprint and manual assembly overhead vs. LLD | Choose for legacy through-hole designs or where thermal mass of DO-35 improves power handling at elevated Ta. |
| MMSZ5232B (Diodes Inc.) | 5.6 V nominal, ±5% tolerance, 150 mW Pd, SOD-123 package (2.7 × 1.7 mm) | Lower power rating limits continuous current to ~27 mA vs. HZK6BL-JTL's ~91 mA (500 mW / 5.5 V) | Choose for space-constrained boards where 150 mW suffices and SOD-123 footprint is already standardized. |
Compared with BZX55C5V6 and MMSZ5232B, the HZK6BL-JTL offers tighter voltage tolerance (±0.5 V vs. ±0.28 V or ±0.28 V), higher power capability (500 mW vs. 500 mW only for BZX55, 150 mW for MMSZ), and a compact LLD geometry optimized for automated SMT - making it preferable for new high-density, thermally demanding, or precision-regulation designs.

FAQ
What is the exact zener voltage range specified for HZK6BL-JTL?
The HZK6BL-JTL is a Grade B device in the HZK6 series, with a guaranteed zener voltage range of 5.5 V to 6.0 V at 5 mA test current. This specification is confirmed in the Renesas HZK Series datasheet Rev.3.00 (May 2003), page 2, Electrical Characteristics table. The "L" suffix denotes lead-free plating, and "JTL" indicates tape-and-reel packaging - neither affects the electrical VZ range. HZK6BL-JTL must be operated within this band to meet its rated dynamic resistance and temperature coefficient.
Is HZK6BL-JTL suitable for automotive applications?
HZK6BL-JTL is classified as a Renesas "Standard" quality grade product, intended for computers, office equipment, audio/video gear, and industrial robots - not for automotive or safety-critical systems. It lacks AEC-Q200 qualification, has no specified PPAP documentation, and its temperature coefficient and lifetime reliability data are not validated for under-hood thermal cycling (–40°C to +125°C ambient). For automotive use, Renesas recommends qualified alternatives like the RLZ series or externally certified Zeners.
What is the thermal resistance of HZK6BL-JTL, and how does it affect power derating?
HZK6BL-JTL does not specify junction-to-ambient thermal resistance (RθJA) in its datasheet. Instead, Renesas provides a derating curve in Figure 3 (page 5): power dissipation drops linearly from 500 mW at 25°C ambient to 0 mW at ~125°C ambient when mounted on a standard 15 × 20 × 1.6 mm FR-4 PCB. This implies an effective RθJA ≈ 250°C/W. Designers must apply this curve directly - no calculation using RθJA is supported by Renesas for the LLD package.
Can HZK6BL-JTL replace a 5.1 V Zener diode in an existing circuit?
No - HZK6BL-JTL is not a drop-in replacement for 5.1 V Zeners due to its higher nominal voltage (5.5–6.0 V). Substituting it would raise reference or clamp thresholds by ≥0.4 V, potentially causing undervoltage lockout failure in MCU reset circuits or incorrect sensor scaling. If 5.1 V is required, consider HZK5B (4.6–5.0 V) or HZK5C (4.9–5.3 V) variants from the same series, which share identical LLD packaging and thermal specs.
Does HZK6BL-JTL have a specified zener voltage temperature coefficient?
Yes - the HZK6BL-JTL exhibits a positive temperature coefficient of +2.0 mV/°C (typical) for its nominal 5.8 V zener voltage, as shown in Figure 2 (page 5) of the Renesas datasheet. This value is derived from the HZK6 series trend line and applies specifically to Grade B devices. Designers should account for this drift when operating across –25°C to +85°C ambient ranges, where total VZ shift may reach ±120 mV.
