Product details
Overview
BZW06-154BH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode with a 154V working stand-off voltage, 171–189V breakdown range at 1mA, and 246V clamping voltage at 2.4A (10/1000μs). It features AEC-Q101 qualification, low dynamic impedance, and sub-1ps response time for automotive-grade ESD and surge protection in power supply rails and signal lines.
For engineers reviewing the BZW06-154BH datasheet, BZW06-154BH pinout, BZW06-154BH application, or BZW06-154BH equivalent, key selection criteria include its DO-204AC (DO-15) package, 175°C max junction temperature, 1.7W steady-state power dissipation, and compliance with IEC 61249-2-21 halogen-free requirements.
Technical Context
The BZW06-154BH operates as a unidirectional avalanche diode, clamping transients above its VWM (154V) by entering breakdown at VBR (min 171V, typ 180V, max 189V) and limiting peak voltage to 246V under 2.4A 10/1000μs surge. Its thermal design relies on RθJL = 60°C/W and RθJA = 100°C/W for lead-attached and ambient cooling paths.
It delivers 600W non-repetitive peak pulse power per JEDEC-standard 10/1000μs waveform, supports 100A IFSM forward surge current, and maintains <1μA reverse leakage above 10V. Polarity is marked via cathode band; terminals are pure tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Same DO-214AA package; lower PPK (600W same), but VBR min 167V, VCL 243V @ 2.4A; no AEC-Q101 option | Not qualified for automotive under-hood use; suitable for industrial/commercial only | Select when AEC-Q101 is not required and SMB footprint is preferred over DO-15 |
| P6KE150A | DO-204AC package like BZW06-154BH; PPK 600W, VBR 167–179V, VCL 243V @ 2.4A; no AEC-Q101, higher IR (~5μA) | Lacks automotive qualification and halogen-free compliance; older platform with wider VBR tolerance | Choose for cost-sensitive legacy designs where AEC-Q101 and RoHS/halogen-free are not mandated |
Compared with SMBJ150A and P6KE150A, the BZW06-154BH provides verified AEC-Q101 qualification, tighter VBR tolerance (171–189V vs. 167–179V), lower leakage (<1μA), and halogen-free construction-making it the preferred choice for new automotive and high-reliability industrial designs requiring full compliance traceability.

FAQ
What is the polarity configuration of the BZW06-154BH?
The BZW06-154BH is a unidirectional TVS diode with cathode band marking. It conducts only when the cathode is at a higher potential than the anode, making it suitable for DC rail-to-ground clamping. This polarity prevents unwanted conduction during normal operation while enabling rapid avalanche breakdown during positive transients on the protected line.
Does the BZW06-154BH meet AEC-Q101 requirements?
Yes, the BZW06-154BH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. It has undergone stress testing including high-temperature operating life, temperature cycling, and ESD per AEC-Q101 Rev D, confirming suitability for automotive under-hood and chassis applications.
What is the maximum clamping voltage of the BZW06-154BH under standard surge conditions?
The BZW06-154BH has a maximum clamping voltage (VCL) of 246 V at 2.4 A under the 10/1000 μs double-exponential surge waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on the protected circuit during a 600W transient event.
Can the BZW06-154BH be used in bidirectional configurations?
No, the BZW06-154BH is unidirectional only. For bidirectional protection, the BZW06-154B variant must be selected. The "BH" suffix denotes AEC-Q101 qualification and unidirectional functionality; using BZW06-154BH in AC or symmetrical transient scenarios will result in improper clamping or device failure.
What is the thermal resistance specification for the BZW06-154BH?
The BZW06-154BH has a junction-to-lead thermal resistance (RθJL) of 60°C/W and a junction-to-ambient thermal resistance (RθJA) of 100°C/W with 10 mm lead length. These values guide PCB layout decisions-such as copper pour area and lead length-to ensure safe operation at 175°C maximum junction temperature under sustained surge duty cycles.
