Product details
Overview
HZK11BTR-S-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage regulation and stabilization in low-power supply circuits. It delivers a nominal zener voltage of 10.2–11.1 V at 5 mA, with dynamic resistance ≤25 Ω, maximum power dissipation of 500 mW, and operates within –55°C to +175°C storage temperature range. It is used in precision reference circuits for industrial sensors and analog front-ends.
For engineers reviewing the HZK11BTR-S-E datasheet, HZK11BTR-S-E pinout, HZK11BTR-S-E application, or HZK11BTR-S-E equivalent, key selection criteria include zener voltage tolerance (±5% at grade B), low leakage current (≤1 µA at VR = 7.5 V), thermal coefficient (≈+4.5 mV/°C), and LLD surface-mount package compatibility with high-density PCB layouts.
Technical Context
The HZK11BTR-S-E employs a planar epitaxial junction structure optimized for stable reverse breakdown behavior under DC bias. Its zener voltage is specified at IZ = 5 mA with test condition VR = 7.5 V, and it exhibits a positive temperature coefficient of approximately +4.5 mV/°C across its operating range.
This device operates strictly in reverse-bias mode for voltage reference applications, with guaranteed parameters including reverse current ≤1 µA at VR = 7.5 V, dynamic impedance ≤25 Ω at IZ = 5 mA, and junction temperature limit of 175°C - all validated per Renesas Rev.3.00 (May 2003) specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.2–11.1 V at IZ = 5 mA - defines stable regulation point for low-noise reference design |
| Dynamic Resistance (rd) | ≤25 Ω at IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Reverse Current (IR) | ≤1 µA at VR = 7.5 V - guarantees low standby power loss in battery-backed circuits |
| Power Dissipation (Pd) | 500 mW - supports continuous operation in compact SMT layouts without forced cooling |
| Junction Temperature (Tj) | 175°C max - enables use in thermally demanding industrial environments |
| Package | LLD - ultra-compact leadless surface-mount package (1.4 mm Ø, 0.027 g mass) |
Pinout & Package
The HZK11BTR-S-E uses the LLD (Leadless Low-profile Diode) package: cylindrical, glass-passivated, 1.4 ± 0.1 mm diameter, 0.35 mm typical height, cathode band marked on top surface. No leads - terminals are metallized end caps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Cathode Band Side) | Cathode | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes VZ |
| Terminal 2 (Opposite End) | Anode | Connected to ground or lower-potential rail; completes bias path for zener conduction |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| BZX55C10 (ON Semiconductor) | 10 V nominal, ±5% tolerance, 500 mW, DO-35 package - larger footprint, higher rd (≤30 Ω) | Through-hole assembly only; unsuitable for high-density SMT designs | Select when legacy through-hole manufacturing or higher surge robustness (1.5 kW peak) is required |
| MMSZ4689 (Vishay) | 10 V nominal, ±5%, 500 mW, SOD-123 - same LLD-equivalent size but higher leakage (≤5 µA at 7.5 V) | Lower production cost but reduced low-power performance in battery systems | Select for cost-sensitive consumer applications where sub-µA leakage is noncritical |
Compared with BZX55C10 and MMSZ4689, the HZK11BTR-S-E offers superior low-leakage performance (≤1 µA) and tighter thermal coefficient control in an ultra-compact LLD package - making it optimal for space-constrained, low-quiescent-current industrial and medical reference designs.

FAQ
What is the exact zener voltage range for HZK11BTR-S-E?
The HZK11BTR-S-E has a guaranteed zener voltage range of 10.2 V to 11.1 V when tested at IZ = 5 mA, corresponding to Grade B tolerance per Renesas Rev.3.00 specification. This range reflects the device's calibrated performance for precision voltage reference use - not a statistical distribution - and is verified during final test screening.
Does HZK11BTR-S-E support automotive-grade temperature operation?
The HZK11BTR-S-E is rated for storage from –55°C to +175°C and junction temperature up to 175°C, but Renesas classifies it as "Standard" quality grade - intended for industrial, office, and communications equipment, not automotive or safety-critical systems. It lacks AEC-Q200 qualification and is not approved for under-hood vehicle applications.
What does the "TR-S-E" suffix in HZK11BTR-S-E indicate?
The "TR-S-E" suffix denotes tape-and-reel packaging (TR), standard reliability grade (S), and RoHS-compliant finish (E). This confirms the HZK11BTR-S-E is supplied in EIA-481-compliant 8 mm carrier tape, with Pb-free matte tin termination and compliance with EU RoHS Directive 2011/65/EU - verified per Renesas environmental documentation.
Can HZK11BTR-S-E be used as a replacement for HZK11C?
No - HZK11C specifies a wider zener voltage range (10.9–11.9 V) and different color coding (Light Blue/Light Blue/Light Blue). The HZK11BTR-S-E matches only HZK11B (10.2–11.1 V, Light Blue/Verdure marking). Substituting HZK11C would shift regulation voltage outside design margins and invalidate calibration.
Is thermal derating required for HZK11BTR-S-E at elevated ambient temperatures?
Yes - per Figure 3 in the Renesas datasheet, power dissipation must be linearly derated above 25°C ambient: Pd = 500 mW × (1 − (Ta − 25)/150). At 75°C ambient, maximum allowable dissipation drops to 333 mW. Layout must ensure adequate copper area and airflow to maintain Tj ≤ 175°C.
