For engineers reviewing the BZD27B200P-HE3_A18 datasheet, BZD27B200P-HE3_A18 pinout, BZD27B200P-HE3_A18 application, or BZD27B200P-HE3_A18 equivalent, this page delivers verified Zener voltage range (196–204 V), dynamic resistance (200 Ω max), clamping voltage (268 V at 5 A), temperature coefficient (0.09–0.13 %/°C), and MSL level 1 reflow compatibility.
Technical Context
This unidirectional silicon planar Zener diode operates as a precision voltage reference and transient voltage suppressor. Its 200 V nominal Zener voltage is specified at 5 mA test current with ±2 % tolerance, and it delivers 268 V clamping voltage at 5 A peak reverse current under 10/1000 μs waveform per IEC 60-1.
The device features low leakage current (≤5 μA at VR = 160 V), excellent long-term stability, and AEC-Q101 qualification for automotive use. Thermal performance is defined by RthJL = 30 K/W and RthJA = 180 K/W on 3 mm × 3 mm Cu pads, supporting operation from –65 °C to +175 °C junction temperature.
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 |
|---|---|---|---|
| SMBJ200A-E3/52 | TVS diode (not Zener); 200 V standoff, 328 V clamping at 10/1000 μs, 600 W peak power | Higher clamping voltage and faster response; suited for high-energy surges but lacks precision regulation | Select when surge energy exceeds 150 W or when tighter clamping voltage is not required |
| BZX84-C200-HE3-08 | SOT-23 Zener; 200 V ±5 %, 350 mW Ptot, 500 Ω ZZ; no AEC-Q101 or surge rating | Lower power capability and wider tolerance; suitable only for low-current reference, not protection | Select only for non-automotive, low-power biasing where cost and size outweigh surge immunity needs |
Compared with SMBJ200A-E3/52 and BZX84-C200-HE3-08, the BZD27B200P-HE3_A18 uniquely combines AEC-Q101 qualification, ±2 % Zener tolerance, 150 W surge rating, and DO-219AB thermal performance-making it the sole choice for automotive-grade 200 V clamping where both precision and ruggedness are mandatory.
