Product details
Overview
P6SMB100AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM = 85.5 V), 137 V clamping voltage at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB100AHE3/52 datasheet, P6SMB100AHE3/52 pinout, P6SMB100AHE3/52 application, or P6SMB100AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode operates as a clamping device that remains high-impedance below its reverse standoff voltage (VWM = 85.5 V) and rapidly transitions to low-impedance conduction above its breakdown voltage (VBR min = 95.0 V, max = 105 V at 1 mA). Its glass-passivated junction ensures stable avalanche characteristics and fast response time (< 1 ns).
Designed for automated SMT placement, it features MSL Level 1 moisture sensitivity, UL 94 V-0 molding compound, and thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. The cathode band denotes polarity, and it supports repetitive surge duty cycle up to 0.01 %.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown) | 95.0–105 V at 1 mA - Confirmed avalanche initiation range under standardized test current |
| VC (Clamping) | 137 V at IPPM = 4.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient |
| PPPM | 600 W - Surge energy handling capacity with industry-standard 10/1000 μs waveform |
| ID (Leakage) | 1.0 μA max at VWM - Minimal reverse leakage preserves signal integrity in standby |
| TJ max | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 5.59 mm body length and 2.20 mm width |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 5.59 mm × 2.20 mm × 1.75 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to system ground in typical unidirectional TVS layout | Low forward voltage drop (VF = 3.5 V at 50 A) enables robust surge shunting to ground |
| Cathode | Protected line connection; marked with band; reverse-biased during normal operation | Defines clamping polarity-conducts only when line voltage exceeds VBR relative to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Glass passivated junction | Ensures consistent avalanche performance and long-term stability under repeated surge stress |
| MSL Level 1 | Zero floor life limitation-no baking required prior to reflow soldering |
| UL 94 V-0 molding | Self-extinguishing encapsulant meets flame-retardancy requirements for safety-critical PCBs |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulses) |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
|
Use Scenario: Protection of 12 V/24 V power rails feeding ECUs, lighting modules, and body control units against load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between supply rail and chassis ground to clamp transients exceeding 85.5 V.

IC Role / Device Role / Timing Role: Mounted adjacent to half-bridge driver outputs to clamp shoot-through-induced voltage spikes on high-side and low-side legs. Use Value: SMB footprint enables compact placement near power stages; AEC-Q101 qualification validates robustness across extended temperature and vibration profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/52 | Same VWM (85.5 V), VC (137 V), and PPPM (600 W), but in smaller SMA (DO-214AC) package with higher RθJA (140 °C/W) | Limited to lower average power dissipation due to reduced thermal mass; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is not required |
| 1.5SMC100A | Same electrical specs but in larger SMC (DO-214AB) package with lower RθJA (60 °C/W); RoHS-compliant but not AEC-Q101 qualified | Better thermal performance for high-duty-cycle surges; incompatible footprint requires PCB redesign | Choose for industrial power supplies needing enhanced thermal margin without automotive certification |
Compared with SMAJ100A-E3/52 and 1.5SMC100A, P6SMB100AHE3/52 uniquely combines AEC-Q101 qualification, SMB footprint compatibility, and validated 150 °C operation-making it the preferred choice for automotive and high-reliability industrial designs where qualification and thermal-limited layouts coexist.

FAQ
What is the maximum clamping voltage of P6SMB100AHE3/52 under standard surge conditions?
The P6SMB100AHE3/52 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 4.4 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the worst-case voltage imposed on the protected circuit during transient events, ensuring downstream components remain within safe operating limits.
Is P6SMB100AHE3/52 qualified for automotive use?
Yes, P6SMB100AHE3/52 is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD robustness-making P6SMB100AHE3/52 suitable for under-hood and chassis-mounted automotive electronics.
What does the "HE3" suffix indicate in P6SMB100AHE3/52?
The "HE3" suffix in P6SMB100AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads compliant with J-STD-002. It distinguishes this variant from commercial-grade "E3" parts and confirms compliance with automotive reliability and solderability requirements.
Can P6SMB100AHE3/52 be used in bidirectional configurations?
No, P6SMB100AHE3/52 is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and presence of a cathode band. For bidirectional operation, Vishay specifies part numbers ending in "CA", such as P6SMB100CA, which provide symmetrical clamping in both polarities.
What is the thermal resistance of P6SMB100AHE3/52 in standard mounting conditions?
P6SMB100AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB layout and natural convection cooling-critical for estimating junction temperature rise under sustained power dissipation.
