Product details
Overview
P6SMB15CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 15 V standoff voltage (VWM), 21.2 V maximum clamping voltage at 28.3 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the P6SMB15CAHE3_B/H datasheet, P6SMB15CAHE3_B/H pinout, P6SMB15CAHE3_B/H application, or P6SMB15CAHE3_B/H equivalent, key selection criteria include bidirectional transient suppression capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.41), RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 12.8 V), while the low incremental surge resistance supports fast energy diversion during ESD or inductive switching events.
The device is rated for 150 °C maximum junction temperature and exhibits a ±0.084 %/°C temperature coefficient of breakdown voltage, ensuring predictable clamping performance across automotive-grade thermal ranges. Its MSL Level 1 rating confirms suitability for standard reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 12.8 V - maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown) | 14.3–15.8 V at 1.0 mA - guaranteed avalanche initiation range; ensures reliable turn-on during overvoltage events |
| VC (Clamping) | 21.2 V at 28.3 A - maximum voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform; defines transient energy absorption capacity |
| TJ max | +150 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with IPC-7351B land patterns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | 400 W PPPM, SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when space-constrained PCBs prioritize size over surge robustness |
| 1.5KE15CA | Through-hole DO-201 package, same 600 W rating but slower response (>1.0 ns) and no AEC-Q101 qualification | Not suitable for automotive or high-reliability SMT production | Choose only for legacy through-hole designs or non-automotive prototyping |
Compared with SMAJ15CA and 1.5KE15CA, P6SMB15CAHE3_B/H delivers superior surge robustness in a qualified SMT package, enabling automotive-grade reliability without layout redesign or thermal derating penalties.

FAQ
What is the clamping voltage of P6SMB15CAHE3_B/H at its rated peak pulse current?
The P6SMB15CAHE3_B/H has a maximum clamping voltage (VC) of 21.2 V at 28.3 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and guarantees that protected circuits will not experience voltages exceeding 21.2 V during specified surge events. The clamping ratio (VC/VWM = 1.41) reflects efficient transient suppression performance for the P6SMB15CAHE3_B/H.
Is P6SMB15CAHE3_B/H suitable for automotive applications?
Yes, P6SMB15CAHE3_B/H is AEC-Q101 qualified and specifically designed for automotive use. Its qualification covers high-temperature operating life, thermal cycling, and humidity testing per automotive reliability standards. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, and the "_B/H" ordering code confirms compliance with automotive-grade packaging and traceability requirements for the P6SMB15CAHE3_B/H.
What does the "CA" suffix indicate in P6SMB15CAHE3_B/H?
The "CA" suffix in P6SMB15CAHE3_B/H designates a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P6SMB15A), the CA version has no cathode marking and functions identically whether voltage is applied anode-to-cathode or cathode-to-anode - essential for protecting AC-coupled or differential signal paths in the P6SMB15CAHE3_B/H.
What is the thermal resistance of P6SMB15CAHE3_B/H from junction to ambient?
The typical thermal resistance from junction to ambient (RθJA) for P6SMB15CAHE3_B/H is 100 °C/W when mounted on the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value assumes still air conditions and directly impacts power derating above 25 °C ambient; for example, at 85 °C ambient, the device's safe continuous power dissipation drops to ~3.0 W. Thermal performance is integral to sustained reliability of the P6SMB15CAHE3_B/H.
How does P6SMB15CAHE3_B/H compare to unidirectional P6SMB15A in terms of circuit implementation?
P6SMB15CAHE3_B/H replaces two unidirectional TVS diodes in back-to-back configuration with a single bidirectional device, simplifying layout and reducing component count. While P6SMB15A requires explicit cathode orientation and protects only one polarity, the P6SMB15CAHE3_B/H eliminates polarity concerns and ensures identical clamping in both directions - critical for differential interfaces like CAN or RS-485 where the P6SMB15CAHE3_B/H provides more robust and compact protection.
