Product details
Overview
P6SMB30AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 30 V standoff voltage (VWM), 31.5 V maximum breakdown voltage (VBR), and 41.4 V clamping voltage (VC) at 14.5 A peak pulse current (IPPM), designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive and industrial power electronics.
For engineers reviewing the P6SMB30AHE3_A/I datasheet, P6SMB30AHE3_A/I pinout, P6SMB30AHE3_A/I application, or P6SMB30AHE3_A/I equivalent, this AEC-Q101 qualified TVS offers verified 600 W peak pulse power (10/1000 μs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial motor drives requiring robust overvoltage immunity without layout redesign.
Technical Context
This unidirectional TVS operates with a cathode-band polarity marking and exhibits fast response time (<1 ns), enabling effective suppression of sub-microsecond transients induced by relay coil de-energization or MOSFET switching. Its glass-passivated junction ensures stable leakage performance and long-term reliability under thermal cycling.
The device delivers 41.4 V clamping at 14.5 A IPPM under standardized 10/1000 μs waveform conditions, with a temperature coefficient of VBR at +0.097 %/°C and maximum reverse leakage ID of 1.0 μA at 25.6 V VWM - confirming tight voltage tolerance and low standby power impact in always-on sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 25.6 V - Maximum continuous reverse operating voltage before clamping begins; sets safe margin below system rail in 24 V automotive applications. |
| VBR (Breakdown Voltage) | 28.5–31.5 V at 1 mA IT - Confirmed avalanche onset range ensuring predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 41.4 V at 14.5 A IPPM - Peak voltage seen by protected circuit during 600 W transient; enables safe operation of 36 V-rated downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges common in load-dump or inductive kick scenarios without degradation. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current draw, preserving battery life in always-on automotive modules. |
| TJ max | 150 °C - Supports operation in under-hood environments and industrial enclosures with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; cathode identified by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; completes clamping loop during transient conduction. |
| Cathode | High-side connection point | Connected to protected line (e.g., 24 V supply or sensor output); conducts avalanche current when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-E3/5B | Same VWM (25.6 V), VC = 48.4 V at 12.4 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a compliance without derating. | Select only for space-constrained consumer boards where 400 W surge margin suffices and AEC-Q101 is not required. |
| 1.5SMC33A | Higher VWM (28.2 V), VC = 53.3 V at 11.3 A; same 600 W rating; larger SMC (DO-214AB) package. | Requires PCB area increase (~30% larger pad layout); higher thermal mass slows response slightly but improves sustained surge handling. | Prefer when board layout allows larger footprint and system requires margin above 30 V nominal rails, e.g., 36 V industrial systems. |
Compared with SMAJ30A-E3/5B and 1.5SMC33A, P6SMB30AHE3_A/I uniquely balances AEC-Q101 qualification, SMB footprint compatibility, and precise 30 V clamping performance - making it the optimal choice for automotive and high-volume industrial designs demanding certified reliability without layout change.

FAQ
What is the clamping voltage of the P6SMB30AHE3_A/I at its rated peak pulse current?
The P6SMB30AHE3_A/I has a maximum clamping voltage (VC) of 41.4 V at 14.5 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain within safe voltage limits during surge events. The P6SMB30AHE3_A/I achieves this with low incremental surge resistance, minimizing voltage overshoot beyond VC.
Is the P6SMB30AHE3_A/I suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6SMB30AHE3_A/I is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix and confirmed in Vishay's ordering information and mechanical data tables. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD, making it approved for use in engine control modules, body electronics, and ADAS subsystems where automotive-grade reliability is mandatory. The P6SMB30AHE3_A/I meets all requirements for under-hood deployment up to 150 °C junction temperature.
How does the P6SMB30AHE3_A/I differ from bidirectional variants like P6SMB30CA?
The P6SMB30AHE3_A/I is unidirectional, featuring a cathode band marking and conducting only in reverse breakdown - ideal for DC rail protection where polarity is fixed. In contrast, P6SMB30CA is bidirectional, symmetric in both directions, and lacks polarity marking; it suits AC-coupled or floating signal lines. The P6SMB30AHE3_A/I offers tighter leakage (1.0 μA vs. 10 μA for some bidirectional versions at VWM) and is optimized for 24 V DC systems, whereas P6SMB30CA supports dual-polarity transients in telecom or audio interfaces.
What is the thermal resistance and power dissipation capability of the P6SMB30AHE3_A/I?
The P6SMB30AHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a steady-state power dissipation (PD) of 5.0 W at TA = 50 °C on infinite heatsink conditions. Its junction-to-lead resistance (RθJL) is 20 °C/W, supporting localized heat transfer to PCB copper pads. These values assume the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per terminal - essential for maintaining reliability during repetitive surge events. The P6SMB30AHE3_A/I must be mounted accordingly to avoid thermal runaway.
Can the P6SMB30AHE3_A/I be used in place of older P6SMB30A variants without design changes?
Yes, the P6SMB30AHE3_A/I is a direct replacement for legacy P6SMB30A parts in terms of electrical specifications, SMB (DO-214AA) package dimensions, pinout, and soldering profile. The "HE3" suffix denotes RoHS-compliant, AEC-Q101 qualified construction with matte tin plating and J-STD-020 MSL Level 1 rating - all backward-compatible with existing footprints and reflow profiles. No PCB or schematic modifications are needed when upgrading to P6SMB30AHE3_A/I from non-qualified P6SMB30A variants.
