Product details
Overview
BZD27B200P-HE3_A08 from Vishay Semiconductors is a 200 V ±2 % tolerance AEC-Q101 qualified Zener diode in DO-219AB (SMF) package, rated for 150 W non-repetitive peak surge power and 2300 mW total power dissipation at TL = 105 °C, used for overvoltage protection in automotive power rails and industrial DC bus monitoring.
For engineers reviewing the BZD27B200P-HE3_A08 datasheet, BZD27B200P-HE3_A08 pinout, BZD27B200P-HE3_A08 application, or BZD27B200P-HE3_A08 equivalent, this page delivers verified Zener voltage range (196–204 V), dynamic resistance (200 Ω max), temperature coefficient (0.09–0.13 %/°C), clamping voltage (268 V at 5 A), and AEC-Q101 qualification status.
Technical Context
This unidirectional silicon planar Zener diode operates as a precision voltage reference and transient voltage suppressor. Its 200 V nominal breakdown voltage is specified at 5 mA test current with ±2 % tolerance, and it exhibits low leakage current (≤5 μA at VR = 160 V) and stable temperature coefficient (0.09–0.13 %/°C).
The device supports wave and reflow soldering per J-STD-020 MSL level 1 (peak 260 °C), meets JESD 201 class 2 whisker test, and delivers 150 W peak surge power under 10/1000 μs waveform - enabling robust protection in high-energy transients without derating at ambient temperatures up to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 196–204 V at IZT = 5 mA; enables precise 200 V rail clamping with ±2 % tolerance for automotive ECU power monitoring |
| Clamping Voltage (VC) | 268 V at IRSM = 5 A (10/1000 μs); defines maximum voltage seen by protected circuit during surge events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-E3/52 | TVS diode (not Zener); 200 V standoff, 222 V clamping, 600 W peak power; bidirectional | Designed for fast transient suppression only; lacks precision Zener regulation for reference use | Select when primary need is high-energy surge handling rather than voltage reference stability |
| BZX84-C200-HE3-08 | SOT-23 package; 200 V ±5 % tolerance; 350 mW power rating; no AEC-Q101 qualification | Lower surge capability (100 W), smaller footprint, not automotive-qualified | Choose for cost-sensitive consumer electronics where AEC-Q101 and 150 W surge are unnecessary |
Compared with BZD27B200P-HE3_A08, SMBJ200A-E3/52 offers higher surge power but no voltage regulation function, while BZX84-C200-HE3-08 provides identical nominal voltage but sacrifices automotive qualification, thermal performance, and surge robustness - making BZD27B200P-HE3_A08 the only option meeting all three criteria simultaneously.

The BZD27B200P-HE3_A08 achieves this specification under standard test conditions defined in the Vishay datasheet Rev. 2.1.
Is BZD27B200P-HE3_A08 qualified for automotive applications?
Yes, BZD27B200P-HE3_A08 is AEC-Q101 qualified, specifically certified for automotive-grade reliability under Rev D requirements. It passes stress tests including temperature cycling, high-temperature operating life, and mechanical shock - confirming suitability for under-hood applications like engine control units, battery management systems, and ADAS modules. The "HE3" suffix explicitly denotes AEC-Q101 qualification, distinguishing it from commercial-grade "E3" variants. BZD27B200P-HE3_A08 maintains full compliance across its -65 °C to +175 °C operating range.
What is the maximum clamping voltage of BZD27B200P-HE3_A08 during a surge event?
The maximum clamping voltage of BZD27B200P-HE3_A08 is 268 V at a peak surge current of 5 A under the 10/1000 μs waveform condition. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during standardized transient events. The BZD27B200P-HE3_A08 achieves this clamping performance while sustaining 150 W peak surge power, making it suitable for protecting sensitive components in 24 V and 48 V automotive and industrial systems. Clamping voltage is guaranteed across the full operating temperature range.
Which package does BZD27B200P-HE3_A08 use, and what are its key dimensions?
BZD27B200P-HE3_A08 uses the DO-219AB (SMF) package, a low-profile surface-mount case with dimensions of 2.7–2.9 mm length, 1.7–1.9 mm width, and 0.8–0.88 mm height. It features a cathode band marking and is compatible with standard reflow profiles up to 260 °C peak temperature (MSL level 1). The BZD27B200P-HE3_A08 footprint requires 1.3 mm × 1.3 mm copper pads with 1.4 mm center-to-center spacing, enabling compact layout in space-constrained modules such as motor controllers and telecom power supplies.
How does the thermal performance of BZD27B200P-HE3_A08 compare to standard SOD-123 devices?
BZD27B200P-HE3_A08 offers superior thermal performance versus standard SOD-123 devices, with a junction-to-lead thermal resistance (RthJL) of 30 K/W and total power dissipation of 2300 mW at TL = 105 °C - more than double typical SOD-123 ratings. This is enabled by the DO-219AB package's enhanced thermal path and larger copper pad interface. The BZD27B200P-HE3_A08 also achieves 180 K/W junction-to-ambient resistance on 3 mm × 3 mm Cu pads, supporting reliable operation in high-power-density automotive and industrial environments where thermal management is critical.
