Product details
Overview
HZK9CLTR-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage regulation and stabilization in low-power supply circuits, with a nominal zener voltage of 8.9–9.7 V (Grade C), 400 mW power dissipation, 60 Ω dynamic resistance at 0.5 mA test current, and LLD surface-mount package. It serves in precision reference and overvoltage protection roles within industrial power management modules.
For engineers reviewing the HZK9CLTR-S-E datasheet, HZK9CLTR-S-E pinout, HZK9CLTR-S-E application, or HZK9CLTR-S-E equivalent, key selection criteria include zener voltage tolerance (±0.4 V), temperature coefficient (−2.5 mV/°C), low leakage (<1 µA at 2 V), junction temperature rating (175°C), and compatibility with high-density PCB assembly using the LLD footprint.
Technical Context
The HZK9CLTR-S-E operates as a two-terminal voltage reference device relying on controlled reverse-breakdown behavior in a silicon p-n junction. Its zener voltage is specified at 0.5 mA test current with tight Grade C tolerance (8.9–9.7 V) and exhibits a negative temperature coefficient of −2.5 mV/°C, indicating decreasing VZ with rising temperature.
It is rated for 400 mW DC power dissipation on a standard PCB, with absolute maximum junction temperature of 175°C and storage range from −55°C to +175°C. The LLD package supports automated SMT placement and provides thermal performance suitable for ambient temperatures up to 75°C at full rated power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.9–9.7 V at IZ = 0.5 mA - defines stable regulation point for low-current bias/reference circuits |
| Dynamic Resistance (rd) | 60 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 400 mW - sets maximum continuous DC power handling on standard PCB layout |
| Reverse Leakage (IR) | ≤1 µA at VR = 2.0 V - ensures minimal quiescent current in standby or sensing paths |
| Temperature Coefficient (γZ) | −2.5 mV/°C - quantifies VZ drift over temperature; enables compensation design |
| Junction Temperature (Tj) | 175°C max - defines upper thermal limit for reliable long-term operation |
| Package | LLD - 2-pin surface-mount package with 1.4 mm diameter cathode band marking |
Pinout & Package
The HZK9CLTR-S-E uses the LLD package: a miniature cylindrical surface-mount diode with axial polarity marking. Cathode is identified by a colored band (Orange/Purple/Light Blue per HZK9CL marking code); anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated output or higher-potential node; reverse-biased during regulation |
| 2 (Unmarked End) | Anode | Connected to ground or lower-potential reference; completes bias path for zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 60 Ω max ensures stable regulation under small-signal load variations |
| Grade C voltage tolerance | ±0.4 V window (8.9–9.7 V) enables tighter reference accuracy than Grade A/B variants |
| High-temperature operation | Rated to 175°C junction temperature supports use in thermally constrained industrial enclosures |
| LLD surface-mount form | 0.027 g mass and compact size allow high-density PCB layouts and reflow-compatible assembly |
| Low leakage current | <1 µA at 2 V reverse bias minimizes error in high-impedance reference divider networks |

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 |
|---|---|---|---|
| BZX84-C9V1 | Same nominal VZ (9.1 V), but SOT-23 package (larger footprint), 500 mW Pd, 60 Ω rd, ±5% tolerance (vs. Grade C ±0.4 V) | Higher power margin but looser voltage spec; less suitable for precision references requiring <±0.5 V tolerance | Select BZX84-C9V1 only if board space allows SOT-23 and ±5% VZ meets system accuracy requirements |
| MMSZ5239B | VZ = 9.1 V, SOD-123 package, 500 mW Pd, 10 µA IR at 7.2 V (vs. ≤1 µA at 2 V for HZK9CLTR-S-E) | Higher leakage limits use in high-impedance monitoring; same thermal rating but different land pattern | Prefer MMSZ5239B only when existing SOD-123 layout prohibits LLD adoption and leakage budget permits ≥10× higher IR |
Compared with BZX84-C9V1 and MMSZ5239B, the HZK9CLTR-S-E offers superior voltage tolerance (±0.4 V vs. ±5%), lower leakage (≤1 µA vs. ≥10 µA), and optimized LLD footprint for high-density industrial PCBs-making it preferred for precision, low-power, space-constrained regulation tasks.

FAQ
What is the exact zener voltage range specified for HZK9CLTR-S-E?
The HZK9CLTR-S-E has a guaranteed zener voltage range of 8.9 V to 9.7 V at a test current of 0.5 mA, corresponding to Grade C tolerance per the Renesas HZK-L Series datasheet Rev.3.00. This 0.8 V window reflects tighter specification than Grade A (±0.5 V) or Grade B (±0.4 V) variants in the same series, making HZK9CLTR-S-E suitable for applications demanding higher reference accuracy without trimming.
Does HZK9CLTR-S-E support reflow soldering, and what is its maximum peak temperature rating?
Yes, the HZK9CLTR-S-E in LLD package is qualified for standard lead-free reflow soldering processes. While the datasheet does not specify JEDEC J-STD-20 profiles, its glass-epoxy PCB mounting data and 175°C maximum junction temperature confirm compatibility with peak reflow temperatures up to 260°C for ≤10 seconds, consistent with IPC-7095 guidelines for small-signal diodes.
What is the reverse leakage current specification for HZK9CLTR-S-E, and at what voltage is it measured?
The HZK9CLTR-S-E has a maximum reverse leakage current (IR) of 1 µA, measured at a reverse voltage (VR) of 2.0 V and ambient temperature of 25°C. This low leakage value is critical for maintaining accuracy in high-impedance reference dividers and battery-monitoring circuits where even nanoamp-level currents affect measurement fidelity.
Is HZK9CLTR-S-E suitable for automotive applications, and what quality grade does it carry?
The HZK9CLTR-S-E is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial, office, and consumer equipment-not automotive or safety-critical systems. Its datasheet explicitly excludes use in transportation equipment without prior written consent, and no AEC-Q200 qualification is indicated. For automotive designs, engineers must select Renesas' "High Quality" graded alternatives or consult official certification status before deployment.
How does the temperature coefficient of HZK9CLTR-S-E impact its performance across operating temperature ranges?
The HZK9CLTR-S-E has a zener voltage temperature coefficient (γZ) of −2.5 mV/°C, meaning its VZ decreases linearly by 2.5 mV per degree Celsius rise in junction temperature. Over a −40°C to +125°C range, this results in approximately ±0.41 V total drift from nominal 9.3 V center, which must be accounted for in precision reference designs-either through compensation circuitry or system-level calibration routines involving HZK9CLTR-S-E.
