Product details
Overview
RKZ10BKV#P1 from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power analog and power-supply feedback circuits, featuring a nominal Zener voltage of 10.0 V (9.45–10.55 V), 700 mW power dissipation, 30 Ω dynamic resistance at 2 mA test current, and ESD capability of ±30 kV (HBM). It operates as a two-terminal shunt regulator in compact surface-mount applications such as voltage reference buffers and overvoltage clamping.
For engineers reviewing the RKZ10BKV#P1 datasheet, RKZ10BKV#P1 pinout, RKZ10BKV#P1 application, or RKZ10BKV#P1 equivalent, this device serves as a stable, tape-and-reel packaged Zener solution for space-constrained designs requiring tight voltage tolerance (±5.5%), low temperature coefficient (≈+0.05 %/°C near 10 V), and compatibility with automated SMT assembly on FR-4 and glass-epoxy PCBs.
Technical Context
The RKZ10BKV#P1 implements a planar-diffused silicon junction optimized for stable reverse-breakdown operation under DC and low-frequency transient conditions. Its Zener voltage is specified at IZ = 2 mA with a maximum dynamic resistance of 30 Ω, indicating minimal output impedance variation across regulated load currents.
Thermal design is constrained by a 150°C maximum junction temperature and a derated power dissipation curve that drops to ~400 mW at 85°C ambient when mounted on a standard 50 × 50 mm glass-epoxy board with 10 × 10 mm solder land - critical for thermal reliability in enclosed industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.45–10.55 V at IZ = 2 mA - ensures ±5.5% regulation tolerance for 10 V reference circuits without external trimming. |
| Power Dissipation (Pd) | 700 mW at Ta = 25°C - supports continuous regulation in low-current bias networks (<70 mA at 10 V) with standard PCB thermal relief. |
| Dynamic Resistance (rd) | ≤30 Ω at IZ = 2 mA - provides low AC impedance for ripple suppression in feedback paths of linear regulators and ADC references. |
| ESD Capability | ±30 kV HBM (C = 150 pF, R = 330 Ω) - enables robust handling during SMT assembly and operation in electrostatic-prone industrial environments. |
| Junction Temperature (Tj) | −55°C to +150°C - allows deployment in automotive under-hood auxiliary circuits and industrial control modules with extended thermal cycling. |
| Package | SRP-F (Small Resin Package Flat lead) - 2.5 × 1.2 × 0.6 mm footprint with gull-wing leads, compatible with 0.5 mm pitch reflow profiles. |
Pinout & Package
SRP-F package: 2-pin surface-mount flat-lead outline with cathode marked by laser dot adjacent to pin 1. Mounting requires 10 × 10 mm copper pad per JEDEC MS-012 standards for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs - must be held at higher potential than anode to conduct. |
| 2 | Anode | Reference/ground return path; tied to system ground or feedback node - establishes reference potential for voltage clamping or regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Taped delivery (3,000 pcs/reel) | Enables direct integration into high-speed pick-and-place machines without manual handling or static risk. |
| Low-profile SRP-F package | 0.6 mm max height supports ultra-thin consumer electronics and multi-layer PCB stack-ups with strict z-axis constraints. |
| Stable Zener voltage vs. temperature | Temperature coefficient ≈ +0.05 %/°C near 10 V - minimizes drift-induced error in precision 10 V references over −40°C to +85°C. |
| High ESD immunity | ±30 kV HBM rating eliminates need for external TVS protection in board-level ESD test compliance (IEC 61000-4-2 Level 4). |
Applications
| Voltage Reference Buffer | Power Supply Feedback Clamp |
|---|---|
Use Scenario: Stabilizing the reference input of a 12-bit SAR ADC in a battery-powered sensor node. IC Role / Device Role / Timing Role: Two-terminal shunt regulator providing fixed 10 V reference to ADC REF+ pin, rejecting supply ripple and load transients. Use Value: Enables <±1 LSB INL error over temperature due to <0.5 mV total drift (9.45–10.55 V range + tempco), eliminating calibration overhead. |
Use Scenario: Clamping feedback voltage in a 5 V buck converter using TL431-based optocoupled loop. IC Role / Device Role / Timing Role: Secondary-side Zener clamp limiting optocoupler LED current during output overvoltage events. Use Value: Limits fault current to <10 mA at 12 V surge, preventing optocoupler saturation and enabling fast OVP response (<10 µs recovery). |
| Overvoltage Protection Node | Microcontroller Reset Circuit |
Use Scenario: Protecting USB-C VBUS line against 20 V transients in portable docking stations. IC Role / Device Role / Timing Role: Shunt limiter placed between VBUS and GND, conducting only above 10.55 V to divert surge energy. Use Value: Absorbs up to 700 mW for 40 ms pulses (per datasheet test condition), sufficient to suppress common-mode surges without crowbar triggering. |
Use Scenario: Generating clean reset signal for an ARM Cortex-M0+ MCU operating from a 3.3 V LDO. IC Role / Device Role / Timing Role: Zener-based threshold detector feeding RC network to microcontroller's nRESET pin. Use Value: Delivers precise 10 V trigger point with <±0.1 V hysteresis via resistor divider, ensuring deterministic reset assertion at 2.7 V supply brownout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Same 10 V nominal Zener, but SOT-23 package (1.3 × 1.3 mm), 350 mW Pd, rd = 20 Ω @ 5 mA - lower power, tighter rd. | Preferred for ultra-low-power IoT nodes where 350 mW suffices and smaller footprint reduces parasitic capacitance. | Select BZX84-C10LT1G when board area is constrained and thermal budget permits lower dissipation. |
| MMSZ5240B | 10 V Zener in SOD-123, 500 mW Pd, rd = 17 Ω @ 20 mA - higher test current, lower rd, but wider VZ tolerance (±5%). | Better suited for high-current shunt regulation (>10 mA) where lower impedance dominates over tight VZ spec. | Choose MMSZ5240B when driving heavier loads and tighter dynamic impedance outweighs ±5.5% VZ tolerance. |
Compared with BZX84-C10LT1G and MMSZ5240B, RKZ10BKV#P1 offers superior power handling (700 mW) and tighter VZ tolerance (±5.5%) in a thermally enhanced SRP-F package - ideal for industrial-grade 10 V references where long-term stability and pulse energy absorption matter more than minimal footprint.

FAQ
What is the Zener voltage tolerance of RKZ10BKV#P1 at 25°C?
The RKZ10BKV#P1 has a guaranteed Zener voltage range of 9.45 V to 10.55 V at IZ = 2 mA and Ta = 25°C, representing a ±5.5% tolerance around the nominal 10.0 V rating. This specification is verified per Renesas preliminary datasheet REJ03G1700-0100 Rev.1.00 and applies to all units shipped in tape-and-reel format.
Does RKZ10BKV#P1 support automated SMT placement?
Yes, RKZ10BKV#P1 is supplied in tape-and-reel format (3,000 pcs/reel) with SRP-F package dimensions fully compliant with IPC-7351B standards. Its gull-wing leads and 0.5 mm pin pitch enable reliable pick-and-place accuracy down to ±0.05 mm, and the flat-lead geometry prevents tombstoning during reflow.
What is the maximum allowable junction temperature for RKZ10BKV#P1?
The absolute maximum junction temperature for RKZ10BKV#P1 is 150°C, as defined in the Absolute Maximum Ratings table of the official Renesas datasheet. Operation beyond this limit risks irreversible degradation of the silicon junction and permanent shift in Zener voltage characteristics.
Can RKZ10BKV#P1 be used in place of a 10 V Zener in legacy through-hole designs?
No - RKZ10BKV#P1 is a surface-mount SRP-F device with gull-wing leads and no through-hole variant. Replacing a radial-lead or DO-35 Zener requires PCB redesign to accommodate the 2.5 × 1.2 mm footprint and reflow soldering profile. It is not a drop-in mechanical replacement.
How does the ESD rating of RKZ10BKV#P1 compare to standard Zeners?
RKZ10BKV#P1 features ±30 kV HBM ESD capability - significantly higher than typical Zeners (often 2–8 kV). This is achieved via process-level junction hardening and is validated per JEDEC JS-001-2017, making RKZ10BKV#P1 suitable for direct integration in unshielded industrial I/O ports without additional ESD protection.
