Product details
Overview
HZK6BTR-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage regulation in stabilized power supplies, with a nominal zener voltage of 5.5–6.0 V, maximum power dissipation of 500 mW, dynamic resistance ≤40 Ω at 5 mA, and operating junction temperature up to 175°C - used in office equipment and industrial control power rails.
For engineers reviewing the HZK6BTR-S-E datasheet, HZK6BTR-S-E pinout, HZK6BTR-S-E application, or HZK6BTR-S-E equivalent, this page delivers verified electrical specs, LLD package dimensions, zener voltage tolerance grade B, thermal derating behavior, and direct alternatives for low-power precision clamping and reference designs.
Technical Context
This device operates as a two-terminal voltage reference using controlled reverse-biased avalanche breakdown in a planar epitaxial structure. Its zener voltage is specified at 5 mA test current with ±0.5 V tolerance (grade B), and exhibits low dynamic impedance (≤40 Ω) ensuring stable regulation under varying load currents.
The HZK6BTR-S-E is rated for 500 mW power dissipation on PCB, with thermal derating beginning at 25°C ambient and full derating to zero at 125°C. It features low leakage (<5 µA at VR = 2 V) and a negative temperature coefficient of approximately –2 mV/°C near 6 V, consistent with mid-voltage Zener devices.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V2 (ON Semiconductor) | 6.2 V nominal, ±5% tolerance (grade C), 500 mW, DO-35 package | Larger DO-35 footprint (4.5 mm length) vs. LLD's 1.4 mm circle; higher rd (≤90 Ω) | Preferred where legacy through-hole compatibility or higher surge robustness is required |
| MMSZ5232B (Vishay) | 6.2 V nominal, ±5% tolerance, 500 mW, SOD-123 package | SOD-123 (2.7 × 1.4 mm) vs. LLD (φ1.4 mm); slightly higher leakage (≤10 µA at 2 V) | Selected when standard SMD footprint alignment with existing pick-and-place tooling is prioritized |
Compared with HZK6BTR-S-E, BZX55C6V2 offers wider tolerance but greater mechanical robustness in high-vibration environments, while MMSZ5232B provides industry-standard SOD-123 compatibility at the cost of marginally higher impedance and leakage - both require layout revision due to differing footprints.

FAQ
What is the exact zener voltage range specified for HZK6BTR-S-E?
The HZK6BTR-S-E has a guaranteed zener voltage range of 5.5 V to 6.0 V when tested at IZ = 5 mA and Ta = 25°C. This corresponds to grade B tolerance per the HZK Series datasheet Rev.3.00. The device achieves this specification using silicon epitaxial planar process technology, and the voltage remains stable within this band across its rated operating current range of 1–20 mA.
Does HZK6BTR-S-E have a specified temperature coefficient?
Yes, the HZK6BTR-S-E exhibits a negative zener voltage temperature coefficient of approximately –2 mV/°C near its 6 V operating point, as confirmed by Figure 2 in the HZK Series datasheet. This value is typical for mid-voltage Zener diodes and must be accounted for in precision reference designs operating across –40 to +85°C ambient ranges.
What is the maximum allowable power dissipation for HZK6BTR-S-E at 75°C ambient?
Per Figure 3 in the HZK Series datasheet, the HZK6BTR-S-E's power dissipation derates linearly from 500 mW at 25°C to 0 mW at 125°C. At 75°C ambient, the maximum allowable power dissipation is 375 mW. This assumes mounting on a standard 15 × 20 × 1.6 mm glass epoxy PCB per the test condition.
Is HZK6BTR-S-E compliant with RoHS and lead-free assembly requirements?
Yes, HZK6BTR-S-E meets EU RoHS Directive requirements and is compatible with lead-free reflow soldering processes. Renesas Electronics confirms environmental compliance for the HZK Series in accordance with applicable regulations, including restriction of hazardous substances such as lead, cadmium, and hexavalent chromium.
What does the "TR-S-E" suffix indicate in HZK6BTR-S-E?
The "TR-S-E" suffix denotes tape-and-reel packaging (TR), standard-grade reliability (S), and RoHS-compliant finish (E). This indicates the HZK6BTR-S-E is supplied in EIA-481-compliant embossed carrier tape, intended for automated SMT placement, and conforms to Renesas Electronics' Standard quality grade for office and industrial equipment applications.
