Product details
Overview
P6SMB36AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 36 V breakdown voltage (VBR = 34.2–37.8 V at 1 mA), 30.8 V stand-off voltage (VWM), and 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current (IPPM). It delivers 600 W peak pulse power with 10/1000 µs waveform and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB36AHE3_A/H datasheet, P6SMB36AHE3_A/H pinout, P6SMB36AHE3_A/H application, or P6SMB36AHE3_A/H equivalent, key selection criteria include clamping performance under 12 A surge, unidirectional polarity with cathode band marking, RoHS-compliant AEC-Q101 qualification, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a unidirectional shunt protector, leveraging an avalanche breakdown mechanism to clamp transient overvoltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and inductive switching events.
The device is thermally rated for TJ = –65 °C to +150 °C, with RθJA = 100 °C/W and RθJL = 20 °C/W, and meets J-STD-020 MSL Level 1 (260 °C peak reflow). It is designed for single-pulse transients per IEC 61000-4-5 (10/1000 µs), not repetitive surge duty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1 mA - defines precise avalanche onset window for reliable clamping threshold |
| VWM | 30.8 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 49.9 V at 12.0 A - peak clamped voltage during 600 W transient, limiting stress on protected circuitry |
| IPPM | 12.0 A - peak surge current capability with 10/1000 µs waveform, derated above 25 °C |
| PPPM | 600 W - transient power handling capacity, validated on 0.2" × 0.2" copper pads |
| TJ max | +150 °C - maximum junction temperature, supporting under-hood automotive environments |
| Qualification | AEC-Q101 qualified - certified for automotive-grade reliability and stress testing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage event |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges without thermal runaway on standard PCB pads |
| Glass passivated junction | Ensures long-term VBR stability and low leakage (<1 μA at VWM) across temperature and lifetime |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure reliability |
| MSL Level 1 rating | Allows direct placement into high-temperature reflow profiles (260 °C peak) without preconditioning |
| Low profile SMB package | Reduces board space vs. SMA/SMB variants while maintaining 600 W capability and automated placement compatibility |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5B | Same VBR range (34.2–37.8 V), but SMA package (DO-214AC); lower PPPM = 400 W; RθJA = 120 °C/W | Less thermal margin in high-density layouts; not AEC-Q101 qualified | Select when cost or legacy footprint drives preference over automotive qualification and 600 W headroom |
| 1.5SMC36A | Same electrical specs, but larger SMC (DO-214AB) package; PPPM = 1500 W; RθJA = 60 °C/W | Higher board area use; better thermal performance but incompatible with SMB land pattern | Choose for industrial designs needing higher surge margin and thermal headroom where space permits |
Compared with SMAJ36A-E3/5B and 1.5SMC36A, P6SMB36AHE3_A/H uniquely balances AEC-Q101 compliance, 600 W capability, and SMB footprint-making it optimal for space-constrained automotive and industrial SMT assemblies requiring validated reliability.

FAQ
What is the breakdown voltage tolerance of P6SMB36AHE3_A/H?
The P6SMB36AHE3_A/H has a breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1 mA test current, representing a ±5% tolerance around the nominal 36 V rating. This tight tolerance ensures predictable clamping behavior in safety-critical automotive and industrial applications where overvoltage margin must be precisely controlled.
Is P6SMB36AHE3_A/H suitable for bidirectional transient protection?
No, P6SMB36AHE3_A/H is a unidirectional TVS diode, identified by its cathode band marking and specified only for reverse-biased operation. For bidirectional protection, Vishay offers the P6SMB36CA variant; using P6SMB36AHE3_A/H in AC or dual-polarity signal paths would result in forward conduction and failure.
What does the "HE3" suffix indicate in P6SMB36AHE3_A/H?
The "HE3" suffix in P6SMB36AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade "E3" parts. The "_A/H" indicates packaging in 7" plastic tape and reel (H) with revision A, meeting automotive traceability and reflow requirements per J-STD-020.
How does P6SMB36AHE3_A/H perform under elevated ambient temperatures?
P6SMB36AHE3_A/H derates linearly above 25 °C ambient: its peak pulse power drops to ~480 W at 85 °C and ~360 W at 125 °C per Figure 2 in the datasheet. Designers must apply this derating when sizing for under-hood or enclosed industrial environments to maintain clamping integrity at full IPPM.
Can P6SMB36AHE3_A/H replace older P6SMB36A parts in existing designs?
Yes, P6SMB36AHE3_A/H is a direct replacement for legacy P6SMB36A parts with identical electrical specs and SMB package dimensions, but adds AEC-Q101 qualification and RoHS compliance. No PCB layout change is needed; however, verify reflow profile compatibility with the MSL Level 1 rating and confirm automotive traceability requirements are met.
